Felicity FLH48100UCG1 High-Voltage BMS Control Unit up to 81.92kWh
A battery tower without its control unit is just a pile of modules: the FLH48100UCG1 is what measures cell by cell, balances, opens and closes the contactor and tells the inverter what is going on. One per cluster.
It manages five to sixteen FLH48100UMG1 modules, 25.6 to 81.92kWh per cluster, and brings the working voltage up to what high-voltage hybrid inverters need. The link to the modules is by contact, with no power wiring to prepare on site.
It communicates over CAN and RS485, has its own screen and is followed from the app. Ten-year manufacturer warranty. We ship within Italy and across the European Union.
