ET-51.2V280Ah-HV high voltage lithium battery energy storage system, consisting of 5- 17 battery modules (51.2V280Ah) and a BCU (Battery Control Unit) in series, with an operating voltage range of 232V-979.2V, is used for household / commercial energy storage applications, working with a high voltage inverter for energy storage purposes.

ET-51.2V280Ah-HV has a built-in BMS (battery management system, including the main BMS in BCU and the slave BMS in battery module), which can manage and monitor battery information, including voltage, current and temperature. In addition, BMS can balance battery charging to prolong service life. BMS has over discharge, over charge, over-current, high / low temperature and other protection functions. The system can automatically manage the charge state, discharge state and balance state.Each battery module is equipped with a cooling fan, plus a porous sheet metal design, which effectively alleviating the problem of working heat.
