Off Grid 30W 3A gate motor & alarm system solar kit with 7A Lithium Battery

Specification: Model: CMP03 Rated Voltage: DC12V Max Current: 3A voltage of solar panels: 36W(3A,12v) Charge-stop Voltage: 14.4V Coefficient of Stop Voltage and Temp: -3mV/ C/cell Supply-stop Voltage: 10.6V Supply-resume Voltage: 12V Light Control Mode: Visibility 20M Working Temp: -10- +40 C; Weight: 33g Function: Prevent the battery from overcharging, discharging, and Reverse discharging to solar panels during the night. The controller will start the lighting system in the evening automatically according to the surrounding luminance. Indicator: One charging indicator, light indicates strong charging, flash indicates float charging, and no light indicates stop charging. For one Load indicator, the light indicates there is power output, the loads could normally working, not the light indicates no output, check whether the battery is in low-voltage or the connection is OK. Attention: Please check the rated voltage of the solar panel and loads, they must be the same as the controller, all their rated voltage should be 6V or 12V. The controller can not short-circuit. Do not use other DC power supplies instead of solar panels for the battery charging through the controller. 30w solar panel specs Maximum Power 30w Open Circuit Voltage 220v Short- Circuit Current 1.84a Maximum Power Voltage 18.0v Maximum Power Current 1.66a Power Tolerance 0 ~+3% Maximum System Voltage Dc1000v Module Application Class A Nominal Operating Temp 45 2 Degrees Celsius Operating Temp 40 Degrees Celsius To + 85 Degrees Celsius 12.8V 7A Lithium-ion battery Specifications: - Nominal Voltage: 12.8V - Nominal Capacity: 7Ah - Energy: 89.6Wh - Internal Resistance(AC): 60m - Cycle Life: >2000 cycles @1C 100%DOD - Months Self Discharge: - Efficiency of Charge: 100% @0.5C - Efficiency of Discharge: 96~99% @1C - Charge Temperature: 0 to 55 @60 25% Relative Humidity - Discharge Temperature: -20 to 60 @60 25% Relative Humidity - Storage Temperature: -20 to 40 @60 25% Relative Humidity - IP Class: IP65 - Plastic Case: ABS What's in the box 3A 14.8V offgrid solar charge controller x1 30w 21.24v solar panel x1 12.8v 7A Lithium-ion battery x1
