Fronus Genki shows BAT_SOC_LOW or BMS low voltage faults

Short answer

BAT_SOC_LOW means the battery charge is low and Fronus asks you to charge it in time. BMS_CELL_LOW_FAULT and BMS_HVB_LOW_FAULT are under-voltage faults from the battery; Fronus says to recharge. BAT_CURR_HIGH means the load is too high.
