The number of batteries you can connect to an inverter cannot exceed 12 times the charging current of the inverter. For example, a 20A charger can handle a maximum of 240Ah of batteries. The formula is A x 12 = battery capacity (Ah). If the inverter demands more current than the battery can safely deliver, the BMS protection kicks in and everything shuts off. If the inverter is undersized, normal appliances. . Many people make the mistake of connecting a 3000W inverter to a single 12V 100Ah battery.
