BDC for XH inverters

The BDC (Bidirectional DC/DC Box) controller is a device located between the inverter and the battery.Its function is to check the charge status of the cells and to balance them, i.e. to charge the cells individually with the appropriate current and voltage.For photovoltaic systems also intended for energy storage, BDC is necessary if the inverter does not have a built-in regulator.The BDC controller designed for MIN XH series inverters supports from 2-7 pieces of Growatt batteries ARK-2.5H-A1 and for MOD XH series inverters, where it supports from 3 to 10 pieces of Growatt batteries ARK-2.5H-A1.
