This controller can only use photovoltaic panels as charging power. Do not use DC or other power as charging power. 3.The LCD display has an error of 0.2 V- 0.3 V, but this is normal 4. Old batteries may be degraded the capacity after hundereds of cycles, easily drop lower than 8V, which results in the controller will be shut off (LCD screen become totally “DEAD”). 5.
