UPS batteries

What is tower UPS?

The Uninterruptible power supply system in tower design that features a quick-access front panel that makes replacing batteries easy is known as Tower UPS. It should be the most well-understood type of server structure, because its shape and structure are similar to those of vertical PCs. Of course, due to the server's motherboard scalability and the number of slots. Therefore, the size of the mainframe is larger than that of the ordinary motherboard. Therefore, the mainframe chassis of the tower UPS is larger than the standard ATX chassis. Generally, sufficient internal space is reserved for future redundancy expansion of the hard disk and the power supply.

What is the difference between a rack UPS and a tower UPS?

In fact, there is no difference in performance between rack UPS and tower UPS. The biggest difference is the installation method.

The rack UPS is installed on a standard rack and is structured like a server. The tower UPS is placed separately, installed on the floor and has space requirements. Whether you choose rack or tower depends on the environment and space of your UPS. The rack UPS can be fixed in a standard network cabinet through rails. The tower UPS is generally placed on the ground and cannot be placed on the rack.

How to choose tower UPS and rack UPS?

The UPS placement environment is the key to distinguish between tower UPS and rack UPS. If a neat machine room or a high-environment working group is required, the rack UPS power supply is required. Meanwhile tower UPS can be placed in a harsh climate or environment. Rack UPS can be installed vertically or horizontally as per requirement elsewhere Tower can be installed only vertically. Considering the heat dissipation tower UPS is better in that case as it is larger in size. In short, choosing between tower UPS and rack UPS should be based on their specific needs and budget.

Even though a UPS unit is effectively just a sophisticated battery, there are tons of little features that can greatly enhance your UPS experience. 

Definition of High Temperature Battery:
High temperature Lead acid battery refers to batteries which are capable to charge continuously at 35°C or above and the operating temperature range is -40°C to +80°C whereas usually the ordinary lead acid battery’s operating temperature range -20°C to +45°C.

High Temperature Battery Design

High Temperature batteries have been designed for countries where temperature is extreme to tolerate (like Middle East , Asian, African countries) and perform simultaneously.  These batteries are suitable for Telecommunication, Uninterruptible power supply, Switchgear, Solar/ Photovoltaic, Data Center, Broadband or many more where temperature is the main reason of damaging batteries frequently.
The High Temperature Battery adopts
-Corrosion resistant battery plate to reduce grid corrosion and charge current density,
-nano carbon to improve durability,
-special positive additive α-PbO₂ to improve the  grid strength,
-optimized valve to tolerate the internal pressure in high temperature,
-reinforced special high temperature resistant ABS container and cover to ensure stable performance.

Advantages:
•12 years design life @35°C (95°F);
•12 months storage life @20°C~25°C;
•Double floating life more than traditional VRLA battery @35°C;
•Greatly reduce operational cost (more than 60% less cooling consumption);
•Up to 100% air conditioner maintenance saving;
•Up to 100% condensing agent saving;
•Up to 25% electricity power saving;

Market Demand:
There is always a great market demand of high temperature batteries because in hot summer many applications temperature raises up to 75°C. High temperatures cannot always be avoided. As a guideline, each 10°C rise in temperature cuts the life of a sealed lead acid battery in half. Therefore, high temperature batteries are designed and developed to sustain up to 80°C.

Rack UPS:

Rack UPS is a power supply equipment mainly used for centralized power supply in security system integration, which is installed on a standard rack and is structured like a server. It is an inevitable product for standardized management and centralized management of security systems.

Diagram of Rack UPS:

Installation method:

The rack UPS can be fixed in a standard network cabinet through rails. Compared to traditional vertical (tower) UPS, the rack UPS can be installed in a standard cabinet, saving floor space, easy to install, use, maintain and can also use a shorter power connection cable. It increases the availability of the entire system by reducing the point of failure between critical equipment and the load. Just like our Power Lead2 Rack UPS. With 19 inch standard rack design, self-adjusting output frequency, smart battery management system and network management, PL2 RM series is a perfect choice for computers, IT equipments and other sensitive devices.

Advantages of Rack UPS:

The installation is simple, the expansion is convenient and the investment is saved. The rack-mounted UPS power supply enables the power supply system to be on demand, enabling the capacity to grow dynamically with the development of the business which not only meets the expansion requirements of the later business but also reduces the initial acquisition cost of the user. Attractive features are Parallel redundancy, stable operation and high reliability. No need for an electrician or facilities involvement. Ability to do your own maintenance/user serviceable.

Disadvantages of Rack UPS:

Not ideal for mission critical equipment that requires high availability. Takes up valuable rack space and limited battery life (2-3years). Not as efficient as 3 phase UPS. Batteries might not be hot swappable.

  Even though a UPS unit is effectively just a sophisticated battery, there are tons of little features that can greatly enhance your UPS experience.

One of the biggest threats to batteries is the temperature. It is vital to keep your batteries in conditions that do not affect their chemistry. Unfortunately, getting the right temperature is never easy. Whereas high temperatures are bad, cold temperatures are not good either. Charging a battery above freezing temperature is one of the biggest challenges for European, American and some other countries.
For low temperature operation, EverExceed offers full range of Nickel cadmium batteries and Lithium iron phosphate batteries for variety types of applications.

Nickel Cadmium Batteries
EverExceed Nickel Cadmium Batteries have been designed in such way to cover wide operating temperature range -40°C to +60°C; specially to sustain in low temperature. These batteries also can tolerate extreme of -50°C to +70°C (-58°F to +158°F) for short periods. Our NiCd batteries have injection moulded plastic grids; both separate plate and insulate plate edges. For extremely low temperatures a special high density electrolyte is used. The block battery fitted with a specially designed flame arresting flip top vent and does not produce corrosive vapours.

Benefits:

·         20+years operating life;
·         Minimal maintenance
·         No downtime
·         No replacement cost

Lithium Iron Phosphate Batteries
EverExceed Lithium Iron Phosphate Batteries can be safely discharged over a wide range of temperatures, typically from –20°C to 60°C, which makes them practical for use in all-weather conditions faced by many potentially low temperature applications. For example, at 0°C a lead-acid battery capacity is reduced by up to 20%, while a lithium iron phosphate battery suffers only a 10% loss at the same temperature. When it comes to recharging lithium-ion batteries, however, there’s one hard and fast rule: to prevent irreversible damage to the battery, don’t charge them when the temperature falls below freezing (0°C or 32°F) without reducing the charge current. Charging below 0°C at an inappropriate charge rate causes the battery to become less mechanically stable.

Benefits:

·         Higher cycle life at 100%DOD
·         Lighter weight to move flexibly
·         Mechanically stable
·         No sudden death

What is Solar battery?

Solar batteries are used to store solar energy (solar electricity) and discharge power as and when needed. Rechargeable solar batteries are used in off-grid PV systems to store excess electricity. Now-a-days solar batteries have been specially designed and optimized for PV system. Each battery has different temperature, mounting, and ventilation requirements.

Types of Solar battery

Batteries used in home energy storage typically are made with one of three chemical compositions: lead acid, lithium ion, and saltwater. In most cases, lithium ion batteries are the best option for a solar panel system, though other battery types can be more affordable.

Which one is the best Solar battery?

For solar home energy system, Lead acid battery is still competitive in market due to its less expensive price than Lithium battery. But Lithium ion batteries are the ideal match for solar energy storage because of its longer life span and higher DOD.

What is Solar Lithium (LiFePO₄) battery?

Solar lithium (LiFePO₄) battery adopts lithium iron phosphate technology which is also optimized specially for solar home system. It is an ideal choice for home energy storage system and SME (small medium enterprise). EverExceed designs two types of Solar Lithium batteries- Rack mounted Solar Lithium battery and Wall mounted Solar Lithium battery to meet the demand of both category installation criteria.

Technical Features:

•Higher life cycle and longer service life;
•Excellent deep cycle ability;
•Rack mounted battery to install in standard rack.
•Wall mounted battery to save the installation space
•Intelligent monitoring system to check technical parameters;
•Lightweight and high energy density standby power;
•High safety, no risk of explosion fire;
•Maintenance free throughout life time;
•Compatible with most of the available hybrid inverters.

Low voltage:

Voltage (V) is the measure of the potential difference between two points in an electrical field. Low enough voltage to be considered safe for indoor domestic use and typically 120 volts or less.

Low voltage UPS:

Uninterruptible power supplies having low voltage are called low voltage UPS. EverExcced offers high efficiency and high quality independent online low voltage UPS which designed in the form of modular UPS, rack UPS and tower UPS. Both single phase and three phase UPS are also available for those countries which use low voltage as well.

In most countries the mains supply is between 220 and 240 volts (50 or 60 Hz); countries that operate on 100-127 volts are greatly outnumbered. There are approximately 40 countries that use 60 Hz while the rest typically run on 50 Hz current. Single-phase power is primarily for residential use (such as homeowners and what you would find in a hotel) while 3-phase electric power provides more stable, heavy-duty power for most industrial applications like manufacturing plants, commercial facilities, data centers, telecom towers, hospitals, food processing, and utility power plants.

Why isn’t there a standard voltage around the world?

Europe and most other countries in the world use a voltage which is twice that of the US. It is between 220 and 240 volts, whereas in Japan and in most of the Americas the voltage is between 100 and 127 volts.

Originally Europe was 120 V too, just like Japan and the US today, but it was deemed necessary to increase voltage to get more power with fewer losses and less voltage drop from the same copper wire diameter. At the time the US also wanted to change but because of the cost involved to replace all electric appliances, they decided not to. At the time (50s-60s) the average US household already had a fridge, a washing-machine, etc., but not in Europe.

USA, Mexico, Colombia, Venezuela, American Samoa, Brazil, Bahamas, Bermuda, Dominican republic, Japan, Ecuador, Honduras, Panama and more other countries are now using low voltage UPS.

In countries having higher voltages, energy losses are lower, but the risk of sustaining injuries is much higher.

High frequency UPS:

High frequency UPS is usually composed of IGBT high frequency rectifier, battery converter, inverter and bypass. The IGBT can control its opening and closing by adding control to the gate. The switching frequency of the IGBT rectifier is usually from thousands of Hz to tens of kHz (even up to a hundred kHz) relative to the 50Hz frequency that is far higher than the low frequency UPS, so it is called high frequency UPS.

With the development of power electronic technology and high frequency power devices have been developed, the UPS power supply products for small and medium power section also gradually become of high frequency. UPS high frequency power supply has the characteristics of high power density, small volume, light weight, occupy a small space. EverExceed high frequency online UPS power series has the advantages of small size, beautiful appearance, high efficiency, advanced and reliable performance and other advantages in one integrated system and it is praised in the global market as well.

Advantages of high frequency UPS:

• Low power consumption
• High input power factor
• Small size, light weight
• Full digital technology
• Small external interference
• Strong ability to adapt to the grid

  It's a rough battle to distinguish which one is better between AGM and GEL. AGM batteries and Gel batteries have a lot in common. Both categorized under Sealed Lead-Acid Batteries. Both batteries possess similar traits such as having deep-cycle capabilities, spill-proof design and both can be used in different orientations. The two battery types are also known for their low self-discharge, maintenance free and vibration-resistant characteristics. However, AGM and Gel are two distinctly different types of batteries.

AGM vs GEL

Structure:

Technical features:

How to choose which battery is suitable:

EverExceed manufactures both AGM and GEL batteries which adopts latest technology. So when trying to decide which battery to purchase consider a few things.
1.What application are you using the battery for?
2.Will the battery have to function in below freezing temperatures or high temperature?
3.How will you recharge the battery?
4.Do you need a slow discharge rate or will you require bursts of power? 

  Invented more than one a half century ago, the lead-acid battery represents the oldest type of rechargeable battery. Moreover, being quite inexpensive as opposed to newer and high-performance technologies, lead acid batteries are used in a wide range of industries.

Lead acid battery maintenance:

Lead-acid battery industry counts for about 15 billion USD, as well as for up to 45% of the total value of batteries sold worldwide. But properly lead acid battery maintenance could be quite difficult, especially if you are not the expert in the electronics field.

Before getting started:

Before getting started make sure you know its exact system voltage, battery compartment size, as well as your energy requirements.

In addition, you should determine the type of lead acid battery used, choosing from high temperature lead acid battery and deep-cycle flooded ones, to AGM or gel batteries. Choosing the right type of battery is essential for your further energy requirements.

Regular maintenance:

Check your batteries on a regular basis to be sure they are getting charged. Use a hydrometer to check the specific gravity of your lead acid batteries. If batteries are cycled very deeply and then recharged quickly, the specific gravity reading will be lower than it should because the electrolyte at the top of the battery may not have mixed with the "charged" electrolyte. Check the electrolyte level in wet-cell batteries at least four times a year and top each cell off with distilled water. Do not add water to discharge batteries. Electrolyte is absorbed when batteries are very discharged. If you add water at this time, and then recharge the battery, electrolyte will overflow and make a mess.

Keep the tops of your battery clean and check that cables are tight. Do not tighten or remove cables while charging or discharging. Any spark around batteries can cause a hydrogen explosion inside and ruin one of the cells and you.

It is a good idea to do an equalizing charge when some cells show a variation of 0.05 specific gravity from each other. This is a long steady overcharge,bringing the battery to a gassing or bubbling state.Do not equalize sealed or gel type batteries.

Fig: Tools required (Hydrometer, Digital battery testers, Adjustable load testers, Constant rate discharge testers)

Storage specification:

All batteries, no matter their type, should be stored at proper temperatures and in proper conditions. Most batteries require a 15 degrees Celsius temperature, or approximately 59 degrees Fahrenheit.

However, extreme temperatures of up to -40 degree Celsius can be achieved for most chemistry.

Batteries should be fully charged and have the proper electrolyte level. Lead-acid batteries self-discharge over time and will need to be recharged to minimum levels even if they are not connected to a load. This rate of self-discharge varies with temperature -high temperatures increase the discharge rate while low temperatures slow the discharge rate.

How to prolong the battery life time?

To keep lead acid in good condition, apply a fully saturated charge lasting 14 to 16 hours. If the charge cycle does not allow this, give the battery a fully saturated charge once every few weeks. If at all possible, operate at moderate temperature and avoid deep discharges; charge as often as you can.

Safety precautions:

Always use extreme caution when handling lead acid batteries and electrolyte. Wear gloves, goggles and old clothes. The sulfuric acid in lead-acid batteries will burn skin and eyes and destroy cotton and wool clothing.

With proper care, lead-acid batteries will have a long service life and work very well in almost any power system. Unfortunately, with poor treatment lead-acid battery life will be very short.

Battery Charger:

A battery charger ,or recharger is a device to put energy into a secondary cell or rechargeable battery by forcing an electric current through it. The charging protocol depends on the size and type of the battery being charged.

Whether it's  your mobile phone, emergency light or the vehicle you own, the extensive use of batteries is evident everywhere. Chargeable batteries are also widely used inverters, where its DC voltage is converted into mains AC voltage and is used to power the household appliances and industries during mains power failure.

Industrial battery charger:

Industrial applications require more ruggedized batteries. Unlike consumer applications, industrial devices are often used in remote, hard-to-reach locations where the device needs to be self-powered and battery replacement and recharging is difficult or impossible. Identifying the ideal power management option is important to these applications because battery failure usually results in failure for the device. As a result, industrial grade batteries must be able to deliver reliable power for as long as the device is able to operate. Some examples include automated utility meters that have to operate up to 25 years outdoors, remote wireless sensors, automotive toll tags, GPS tracking devices, oceanographic instruments as well as process control and monitoring devices used in remote locations. Battery chargers with special features that are subjected to this kind of extreme environmental conditions are called industrial battery chargers.

The importance of  battery charger:
A good battery charger provides the base for batteries that are durable and perform well. In a price-sensitive market, chargers often receive low priority and get the “after-thought” status. Battery and charger must go together like a horse and carriage. Prudent planning gives the power source top priority by placing it at the beginning of the project rather than after the hardware is completed, as is a common practice. Engineers are often unaware of the complexity involving the power source, especially when charging under adverse conditions.

Owing to our experience and knowledge in this arena, EverExceed is able to offer our clients an impeccable range of Industrial Battery Charger that is precision engineered with the industry laid standards and guidelines. Offered range is acknowledged in the market for their attributes like robust construction, durable standards and optimum performance.

How do I check the settings of my battery charger?

Technologies improve and chargers change. That is why you always need to read the manual included with the charger and follow the instructions stated within.

Before starting to use your new battery charger, it is important to check the input voltage. This is especially needed in case of a conventional charger. High frequency chargers adjust to this automatically.  If you don't do this, there is a chance that you will damage the charger.

How do I check the input voltage?

• Measure the voltage on the socket by means of a multi meter
• Open the battery charger
• Set the charger so that you can connect it correctly.

E.g. if the input voltage is 230 V, you can set it accordingly and correctly connect it to 230 V. 

A solar security camera system has the unique ability to be used as a video monitoring systems in wide open, outdoor areas devoid of any power lines and electrical outlets. Whether you’re looking for a security camera to reach a difficult area or want an environmentally friendly option, solar powered security cameras are a great option. Before buying a solar powered security camera, it’s important to understand how they work so that you can make the right decision for your security needs.

What are solar powered security cameras?

Solar powered security cameras, also commonly referred to as solar panel security cameras harness the sun’s energy to power the compatible security camera.

How do solar powered security cameras work?

Solar powered security cameras use solar panels to harness the sunlight and convert that sunlight into direct current (DC) electricity. An inverter then transitions the direct current to an alternating current (AC), which can then be used to power the security cameras.

What kind of Solar Security Cameras EverExceed offers?

EverExceed offers most advanced and affordable weatherproof outdoor solar cameras which support both wifi and 4G network to ensure trouble free operation with high resolution 1080P video, durable construction and powerful mobile app that enables you to view live footage and speak to anyone within range of the camera. It has impressive 145° field of vision along with motions detection keep you update with instant alert notification.

What happens when it rains or is overcast – do solar powered security cameras work?

EverExceed Solar Security Cameras adopt IP67 technology to withstand snow, rain, dust, and direct sunlight keeping your property protected year round. The cameras also come with built in 5200mAh x 2 (10400mAh) lithium batteries to provide alternative backup power. The monocrystalline solar panel not only powers the security camera but also recharges the batteries.
Solar powered security cameras help you keep a close eye on your yard without paying for the increased electric bill that comes along with traditional cameras. There are many high-quality options out there but it depends on you whether you choose to be a part of using sustainable clean energy or not. The more use of solar power, the more green our environment will be. 

Deep cycle battery:

A deep-cycle battery is a battery designed to be regularly deeply discharged using most of its capacity.

Deep cycle batteries are designed to be discharged down as much as 80% time after time and have much thicker plates. The major difference between a true deep cycle battery and others is that the plates are SOLID Lead plates - not sponge. This gives less surface area, thus less "instant" power like starting batteries need. Although these can be cycled down to 20% charge, the best lifespan vs cost method is to keep the average cycle at about 50% discharge.

The level of discharge is the “deep cycle” and stands in contrast to other types of batteries that provide only short bursts of energy before they need to be recharged. To be specific, a starter battery discharges only a tiny percentage -- usually 2 to 5% -- each time it is used.

Types of deep cycle battery:

Even among deep cycle batteries with similar functionality, there are different types. The two most common types of deep cycle batteries are flooded deep cycle batteries and sealed or “maintenance-free” deep cycle batteries. Further, flooded deep-cycle batteries can be divided into subcategories of Tubular-plated or flat plated. The difference generally affects the cycle life and performance of the cell.

Flooded deep cycle batteries require regular monitoring. When the electrolyte levels are low in this type of battery, the user must refill the battery appropriately to maintain performance. EverExceed Deep Cycle AGM battery and Deep cycle GEL battery are perfectly suited for float and cyclic application under extreme environment. EverExceed Tubular-plated OPzS range battery are popular for long durability, high reliability and low maintenance.

“Maintenance-free” batteries, which are also called “Sealed” or “Valve Regulated Lead Acid” batteries are sealed and do not require watering, although regular inspection is still recommended.

Although still much more expensive than traditional lead-acid, a wide range of rechargeable battery technologies such as lithium-ion are increasingly attractive for many users. Such as EverExceed Deep Cycle LDP Series Lithium Iron Phosphate (LiFePO4) Battery are developed to deliver high efficiency energy output compared to equivalent lead acid batteries.

When to use a deep cycle battery?

Deep cycle batteries provide sustained energy, making them ideal for certain applications that require more than a quick start. Some of the most common uses for deep cycle batteries include:

• Marine applications
• Recreational vehicles
• Materials handling, including forklifts
• Golf carts
• Off-grid renewable energy

EverExceed has excellent deep cycle life and maintenance free AGM, Gel Lead Acid batteries and environment friendly Lithium batteries designed for frequent cyclic charge and discharge applications under extreme environments. These batteries perfectly fulfill the requirement for many different applications including telecommunications, medical equipment, industrial and utility applications where frequent deep cycles are required and minimum maintenance is desirable.

a)What are the important and necessary kits that a solar camera consists of?
1.Solar Panel
2.Built in battery
3.A camera
4.SD card
5.Antenna

Solar panel: The best quality solar panel which maximizes the efficiency and performs in low light is ideal for a security camera. While choosing camera it’s also important to look into the types of solar panel. Choosing monocrystalline solar panel will be wiser than polycrystalline solar panel.

Battery: The life span of solar camera depends on the life of the battery. Its battery must have long cycle life, fast and deep discharging capability. It must have a high speed charging and extremely low self discharge. It must be resistant to vibration as well as a wide operating temperature range. Lithium iron Phosphate (LiFePO4) battery is the best choice for longer service life.
Camera: The camera is the most vital part itself consisting with 2.0 megapixels 1080P HD quality, two way intercom, induction lump, IR technology, motion sensor and weather protective body.
SD card storage: The solar powered security cameras with SD card (slot) can record motion detection events onboard even when there is no WiFi / Internet. So SD card slot is important to include in choosing solar camera. SD cards that supports up to 64GB is considerable to store data while network is absent.
Antenna: The solar power camera is wireless and runs by internet whether it is wifi or 4G network. The antenna simply activates the camera by connecting with wireless network.

b)What are the special features that make a solar camera complete surveillance system?
1.Weather protection
2.Built in charge controller
3.Intercom
4.HD video Quality
5.Night vision
6.Remote control
7.Motion sensor

Weather protection: Choose the solar security camera which offer good IP rating (EverExceed offers IP67 ) and can withstand heavy rainfall, hailstorms, gusty winds, snowfall, sleet, fog, haze, mist, smog and pollen.

Built-in charge controller: Pick the solar security camera that has a built-in microcontroller for digital accuracy. It must be able to detect day and night using the PV array. It must operate fully automatically. It must have LVD (low voltage disconnect) override protection.
Intercom: Select the ones which have two way intercom. This feature will help you to talk both way to the visitors on your doorstep, while you are busy inside your house. You can also warn from other side if any unexpected thing happens.
High definition video quality: Remember the higher the camera resolution, the sharper the images. 1080P and higher resolution are ideal for the best and clearest view. HD 1080P also ensures clear view even in night to identify the subject.
Night vision: This is the most important thing to consider. To get the best night view, select a solar security camera with an infrared technology (IR). IR sends bright light through wavelengths. The number of infrared LEDs used in your camera will determine how far it can see. Buy the one with a built-in IR cut-switch that automatically enables and disables the IR depending on the lighting conditions.
Mobile remote control: Pick the solar security camera that is able to live stream feed directly to your smartphone or ipad. If you go away for holidays, this feature will keep you aware and carefree. Make sure the camera is compatible with your specific smartphone or ipad.
Motion sensor: Last but not the least is motion sensor. It helps to send you instant alert message to know what is happening outside. The most important advantage is that it saves energy of solar camera. During night if there is no movement the camera will go to sleep mode automatically and if there is any movement it wakes up automatically and starts recording. Microwave motion sensor provides you the most accurate detection and it is ideal for wide open space.

  Power outages are one of telecom companies’ worst nightmares, as they lead to loss of revenue, customers, image, and so on. In response, internet and telephone providers have expressed a keen interest in having a power backup system. There is a wide choice for telecom companies regarding which backup system they want such as diesel and natural gas generators, fuel cells and batteries.

Types of batteries used for telecommunication:

Batteries convert chemical energy directly into electrical energy. Telecom power systems are responsible for every-day internet, high-speed data, telephone, and other communication services. As global demand for these services continues to increase, the need for reliable wireless telecom battery backup equipment rises. The batteries used in telecom sector are mainly two types:

• Lead acid battery
• Li-ion battery

The majority of batteries used in the telecom industry are a Lead-Acid type. The lead-acid battery segment contributed the majority of shares toward the battery market in telecommunication industry. Lead-Acid batteries are an inexpensive design compared to newer technologies such as Lithium-Ion; however, Lead-Acid batteries have a lower energy density, meaning that larger and heavier batteries are required to produce the same power equivalence of a smaller, Lithium-Ion battery.

Valve-regulated (commonly referred to as sealed) lead-acid batteries are normally used as the backup power source for telecom power systems, due to their low operating costs. The battery string is comprised of 24 series-connected battery cells to make 48V. The battery plants are normally designed to support the telecom load to a final battery voltage of 1.75~1.8V/cell.

In the other hand, Li-ion batteries have definite technical advantages in terms of power to weight to volume ratio, absence of pollutants like acid and lead. Lithium-ion or Li-ion batteries have more than double life than of traditional lead-acid batteries and thus help to cut cost. Lithium-ion (Li-ion) — Telecom systems need small power sources to back-up the supply to mobile-phone relay stations, cable TV terminals and other facilities. Because these power systems need to be small and lightweight, they need to use batteries with an energy density higher than that of VRLA batteries.

Important criteria while choosing battery backup:

Among several kinds of lead acid batteries, some models are usually designed or chosen specially for Telecom market to ensure maximum performance according to the load capacity. Here is some important criteria while choosing battery:

• Special design comply with telecom 19''/ 23'' cabinet for space limitation;
• Deep cycle ability and high cycle life;
• Wide operating temperature range as well as high  temperature sustainability;
• Maintenance free battery for trouble free operation in remote site;
• Negligible gassing ;
• Spill proof and leak proof ;

• Scalable;
• Operation in any suitable position;
• Compatible with off-grid energy storage system.

In compatible with the above criteria EverExceed offers an extensive portfolio of Modular Range VRLA battery, Modular Max range VRLA, Front access FT range VRLA, Front access FT Gel range VRLA, Unilyte range VRLA, High rate range VRLA, Standard range VRLA, Tubular OPzV range VRLA, Flooded Tubular OPzS and Lithium Iron batteries as well as rectifier system to serve the telecommunications industry. Our batteries are featured with excellent deep cycle ability, wide operating temperature range, long life, compact footprint, high energy density and ease of installation. The design of the batteries and rectifier system are ideally suitable for a wide range of wireless telecom applications, including indoor and outdoor BTS. 

Take EverExceed Solar Powered Security Camera which is a great choice for those who want to keep their home secure without raising their electricity bill. It is a self sufficient system that comes with a rechargeable Lithium Iron Phosphate battery and offers a high grade monocrystalline solar panel to get non-stop power. When the sunlight is not available, the wireless solar powered security cameras can still get power from the rechargeable batteries which stores excess electrical power generated by the solar panel.

One of the top benefits is that you can install a solar security camera anywhere you wish. In rainy or foggy days, the WiFi solar security cameras can still work as normal – sufficient sunlight is absolutely the best! Since the EverExceed Solar Security Camera comes with the weatherproof design, you don't need to worry about them in rainy days.

A data center PDU is a power distribution unit designed for the data center market. The specification of your PDUs will have a direct influence on reliability, flexibility and scalability of your data center. And there are different types of data center PDUs, depending on the features and benefits that they bring.   It could be a Basic unit with no network connectivity, a Metered PDU with a built-in power display, a Smart PDU with built in monitoring and intelligence, or a Switched PDU with command and control functionality.

It depends on a set of very basic questions.
• Do you have single-phase or three-phase power?
• Do you want a horizontal or vertical rack PDU amount?
• What are your approximate amperage and voltage requirements?
• What cord length and plug type are required, based on your region?

EverExceed also offers customized PDUs according to customer needs with 139 profiles and open side space facilities to meet the requirements of modern data centers.

Lithium Battery for Solar street lights are becoming more and more main stream solution. We all know that lithium batteries are still very expensive considering other types, but it is fair to say that they became much more affordable for solar street light integration. In last 6 years the cost of lithium battery dropped by almost 80%. There are different types of lithium batteries that can be used for Solar Street Light systems. Our experience showed that definitely the best solution is the LiFePO4 battery.

The advantages of Lithium Iron Phosphate Battery (LiFePO4) battery for Solar Street Light:

Deep cycle life: To reliably power a street light, a battery bank must charge in the few hours of intense sunlight and discharge throughout the evening and night. So, deep-cycle batteries are necessary and LiFePO4 batteries performs 3000 cycles (@100%DOD) whereas VRLA batteries can only perform 300-800 cycles(@100%DOD).

Long service life: LiFePO4 battery packs, are widely used in the solar street light which has longer service  life (more than 5years) than lead-acid battery (less than 3years, even less than 1year).

High temperature sustainability: Lithium batteries can also withstand a wider temperature range than VRLA batteries. VRLA battery life is reduced by 50% for every 10°C (°F) increase above 25°C (77° F) ambient temperature whereas in case of LiFePO4 battery it only reduces 10-20%.

Safety: The LiFePO4 battery is in-built. It is fixed inside the LED far up the pole which makes it impossible for thieves to steal.

Easy installation: The solar panel and LED lights were connected to Lead Acid batteries with the help of a long cable which made the installation process complicated. Whereas in the case of lithium Iron Phosphate batteries, these losses are greatly reduced due to the battery being in close proximity of LED lights and solar panels.

Maintenance Free: Lithium Iron Phosphate batteries do not need water-topping! They are non-aqueous, light in weight, long lasting. Plug and forget.

A solar charge controller is fundamentally a voltage or current controller to charge the battery and keep electric cells from overcharging. It directs the voltage and current hailing from the solar panels setting off to the electric cell.

•Monitors the reverse current flow

The primary function of a solar charge controller is to prevent the battery from being over/under charged by the solar array. Most charge controllers have various set-point points for regulation based on battery voltages; these set-points can be fixed or variable. The charge set-points should be adjusted for temperature with either a local or remote temperature probe.

MPPT Charge Controller

PWM regulators are similar to series regulators, but they use a transistor instead of a relay to open the array. By switching the transistor at high frequency with various modulated widths, a constant voltage can be maintained. PWM controllers make a direct connection between the solar array and the battery bank. PWM controllers use Pulse Width Modulation to charge the battery.

A PWM controller does not send a steady output but rather a series of short charging pulses to the battery. Depending on the battery’s current state of charge, the controller decides how often to send such pulses and how long each one of them should be. For a nearly fully charged battery, the pulses will be short and rarely sent, while for a discharged battery they will be long and almost constantly sent. Ever Pro Series is a high efficient PWM Solar Charge Controller.

The Maximum Power Point Tracking (MPPT) charge controller takes the PWM to the next level, by allowing the array voltage to vary from the battery voltage. By varying the array input, the charge controller can find the point at which the solar array produces the maximum power.

For example, if the output voltage of the solar array (24V, 48V or more) is higher than the battery bank voltage (e.g. 12V), an MPPT controller brings it down to 12V but compensates the ‘drop’ by increasing the current, so that the power remains the same. The principle of MPPT is squeezing the maximum possible solar-generated power from a solar panel by making it operate at the most efficient combination of voltage and current, also known as ‘maximum power point’. Titan Series, Titan Plus Series and Titan Star Series are highly efficient solar MPPT charge controller

Solar energy works by capturing the sun's energy and turning it into electricity for your home or business. Solar energy is becoming an increasingly popular form of alternative energy around the world. Solar batteries enable us to store more free energy form sun through our panels and buy less from energy supplier, saving money and incresing our independency from national grid. There are some battery options that you can choose for your solar powered solution which include the sealed lead-acid, lithium batteries and NiCd batteries. Let's go through them one by one to help you understand in details:

1) Lithium ion battery:

The majority of new home energy storage technologies, some form of lithium ion chemical composition are used . Lithium ion batteries are lighter and more compact than lead acid batteries. They also have a higher DoD and longer lifespan when compared to lead acid batteries.  However, lithium ion batteries are more expensive than lead acid counterparts.

The most popular Lithium-Iron phosphate (LiFePO4) batteries for solar applications are the smallest, lightest, and safest batteries with the longest life span – up to 20 years. They also have the best discharge efficiency, making them especially useful in applications where the system is not in continuous use. EverExceed designs & manufactures advanced lithium battery solutions to provide ideal energy for solar. There are Wall mounted and rack mounted Solar Lithium Iron batteries and LDP Series Lithium Iron ( LiFePO4 ) battery those are developed to deliver high efficiency energy output. Another addition is Solar street light lithium battery which becomes most popular in recent days for its reliability, durability and safety.

2) Lead acid battery:

Lead acid batteries are a tested technology that has been used in off-grid energy systems for decades. While they have a relatively short life and lower DoD than other battery types, they are also one of the least expensive options currently on the market in the home energy storage sector. For the construction mechanism, these batteries discharge slowly.

In EverExceed VRLA batteries, the nano-carbon slows sulfation and allows the battery to charge faster and cycle more than traditional lead acid. EverExceed offers wide range of VRLA batteries specially designed for renewable energy applications. These are:

1. Deep Cycle AGM Range Solar VRLA

2. Deep Cycle Gel Range VRLA

3. Solar Gel Range VRLA

4. Modular Max Range VRLA

5. Modular Range VRLA

6. Modular Gel Range VRLA

7. Tubular OPzV Range VRLA

8. Unilyte Range VRLA

3) NiCd battery:

Traditional pocket plate NiCd has many good points like low self-discharge, non-freezing and so on. But their cycle life is not as good as lead acid battery. This makes them good for emergency/standby systems, but not for systems with a daily cycle. So, NiCd batteries are not recommended for most solar or backup power systems.

Batteries in solar applications have to meet the demands of unstable grid energy, heavy cycling (charging and discharging) and irregular full recharging. There’s a variety of battery types fitted for these unique requirements. EverExceed manufactures complete power solution to meet these requirements for solar applications. Our solar products are highly developed, economical and environment friendly and ensure maximum efficiency and high power output to supply outstanding power performance.

When you install a solar energy system on your property, you save money on your electricity bills and protect yourself against rising electricity rates in the future. How much you can save depends on the utility rates and solar policies in your area, but going solar is a smart investment regardless of where you live.

Solar power, like other renewable energy resources, has many environmental and health benefits. Going solar reduces greenhouse gas emissions, which contribute to climate change, and also results in fewer air pollutants like sulfur dioxide and particulate matter, which can cause health problems.

Net metering is the system that utilities use to credit solar energy system owners for the electricity produced by their solar panels. With net metering, you only pay for the electricity that you use beyond what your solar panels can generate. Net metering policies differ from state to state or city to city, so make sure to do your homework ahead of time. EverExceed EHCS inverter can provide you accurate net metering with a competitive solution.

The amount of power your solar energy system can generate is dependent on sunlight. As a result, your solar panels will produce slightly less energy when the weather is cloudy, and no energy at night. However, because of high efficiency and advanced method, EverExceed solar panel can generate maximum amount of energy in a cloudy weather.

Solar panels convert sunshine into power, so if your panels are covered in snow they can’t produce electricity. Snow generally isn’t heavy enough to cause structural issues with your panels, and since most panels are tilted at an angle the snow will slide off. If snow does accumulate, your panels are easy to clean.

Southerly-facing roofs with little to no shade and enough space to fit a solar panel system are ideal for installing solar. However, in many cases there are workarounds if your home doesn’t have the ideal solar roof. Regarding it, to learn more about all of your options you can contact EverExceed anytime to provide you excellent financially viable solution which generate maximum amount of energy.

In general, solar panels are very durable and capable of withstanding snow, wind, and hail. The various components of your solar power system will need to be replaced at different times, but your system should continue to generate electricity for more than 25 years.
