Explore High Voltage Lithium Batteries for Commercial Storage Solutions
ESS-GRID series is BSLBATT’s self-developed and manufactured pure battery system for commercial and industrial solar energy storage. The 100kWh battery system consists of 10 series-connected LiFePO4 51.2V 205Ah batteries controlled by a high voltage box, and it can be used in conjunction with a power conversion system (PCS) and an integrated PV storage inverter.
ESS-GRID S205 is a high voltage battery system for indoor scenarios, with a total voltage of 512 V. This 100kWh battery also supports parallel connection, so you can choose 1-10 systems for expansion to meet the needs of different capacities of energy storage and power backup.
