100% Safety & Reliable
Our PowerBox T100 is a 48V 100ah lithium telecom battery. This lithium iron phosphate (LiFePO4) battery is ready to replace your lead-acid battery bank in your energy system. It’s powerful, rugged, and has an extremely long cycle life. The 48V100 battery can store more energy and charge faster than lead-acid battery alternatives. With its technology, the 48V lithium-ion battery can be installed in any position (vertical, side-lying, or head-down). The electrical parameters of the 48V LiFePO4 battery are compatible with the AGM's 12V lead battery in all respects. In the vast majority of cases, the charging system can remain the same, without the need for additional accessories to be replaced. It is designed to replace 12V batteries (lead-acid, AGM, or OPZ batteries) that are low performance and environmentally harmful (using heavy metals and acidic electrolytes).

Q. Why do off-grid systems need energy storage batteries?
A: First, photovoltaic power generation time and load electricity time may not be synchronized, a photovoltaic off-grid system, the input is a component, used to generate electricity, the output receives the load. Photovoltaic are daytime power generation, there is sunlight to generate electricity, often at noon to generate the highest power, but at noon, electricity demand is not high, a lot of household off-grid power station only at night with electricity, that the electricity sent during the day how to do, to first energy storage up, this electricity storage equipment is energy storage batteries. And other electricity peaks such as seven or eight o'clock in the evening, and then the electricity will be released.
Second, photovoltaic power and load power may not be the same, photovoltaic power generation is affected by radiation, not very stable, and the load is not stable, like air conditioning, refrigerator, start power, usually running powerless, if photovoltaic directly with load, will cause system instability, voltages fluctuate. The storage battery is a power balancing device, when the photovoltaic power is greater than the load power, the controller will send the excess energy to the battery storage, when the photovoltaic electricity can not meet the load needs, the controller and the battery power to the load.
Q. What is the purpose of a battery storage power plant?
A: On the power generation side, large-scale battery energy storage power station can participate in grid frequency regulation/voltage regulation as an independent power station, provide standby, peak shaving, and valley filling, and also cooperate with renewable energy generation to improve renewable energy online power; on the transmission side, it can be used as an alternative for transmission grid investment upgrade, delay grid upgrade, and provide secondary frequency regulation service for the grid; on the distribution side, it can delay the upgrade of the distribution grid, and improve the operation of the distribution grid. Safety and economy and improve the ability to accept distributed power supply; on the customer side, price arbitrage through the price difference between peaks and troughs, and participate in demand-side response to gain revenue.
Q. Does an off-grid PV system work without batteries?
A: An off-grid system without batteries can be used at night or on cloudy days when there is not enough power. To also use electricity at night, you need to be equipped with a large number of power batteries or mixed with the utility power automatic switching. But there is still a problem with the off-grid and utility hybrid, if you do not use batteries at all, the moment of automatic switching to utility power will probably cause damage to the computer hard drive and some sophisticated equipment that can not be suddenly cut off, so you must use batteries.
