Name: LCD screen solar controller Voltage: DC 12V / 24V Display: LCD screen Self-consumption. 1X Solar Panels Battery Charge Controller 1X User Manual. The charge regulator is only suitable for lead-acid batteries: OPEN, AGM, GEL, it is not suited for nickel hydride, lithium, Liions, or other batteries. This controller can only use photovoltaic panels as charging power. Do not use DC or other power as charging power.
The LCD display has an error of 0.2 V- 0.3 V, but this is normal. 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"). Indoor use only: the working temperature of this controller is -35°C to +60°C, during hot sunny days, the temperature outside might go up to 60-75°C. Please do keep the controller stay in cool and well-ventilated place to maintain good heat dissipation.
