Felicity FLS48100SCG1 Low-Voltage BMS Base for FLS48100SMG1 Modules
A battery tower without its control unit is just a pile of modules: the FLS48100SCG1 is what measures cell by cell, balances, opens and closes the contactor and tells the inverter what is going on. One per cluster.
It closes the group of FLS48100SMG1 modules at 51.2V and acts as the base of the stack: the BMS sits at the bottom, the modules pile on top. This is what you need when the hybrid inverter works at low voltage, which covers the large majority of residential systems.
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.
