Big Capacity 2MWh 500KW Battery Energy Storage Systems (BESS) Scheme For Commercial Project
2. Designed for indoor and outdoor installation
Checking such different energy storage systems examples we can find that the large scale ESS systems are supported by professional suppliers. We have an engineering team to make better solutions for different cases.
Adopted with Grade A prismatic cells, the container battery system with up to 6500 cycles can last for over 15 years lifespan. Each unit battery pack is built in an intelligent battery management system(BMS) that offers safeguards against over-voltage, over-temperature, over-current, over-charge and short circuit. The container system is also packed with a fire extinguisher system, temp system, lighting system, cooling system, and so on.

FAQ
Q：How long does it take to fully charge the battery?
A： The charging time of the battery will vary based on the total power of the solar panles and the weather.
Q：How do I activate the battery?
A：Before utilizing your battery for the first time, it is important to activate it by charging and discharging with a current greater than 1A, and to measure the terminal voltage to confirm it is functional. To prolong the battery's lifespan, it is recommended to disconnect it from the system before prolonged storage. After 24 hours, the battery will enter its automatic mode.
Q：What is the lifespan of LiFePO4 batteries?
A：LiFePO4 batteries have a lifespan of over 6500 cycles at 80% depth of discharge. With daily charging and discharging, these batteries can last more than 15 years.
