Solar Charge Controller 40A, Intelligent Battery Regulator for Solar Panel LCD Display with USB Port (40A)

This intelligent solar charge controller automatically manages the operation of the solar panel and battery in a solar system. It helps extend battery life by shutting off automatically when the battery voltage drops below 8V (the LCD display will also turn off at that point).

Specifications:

Battery Voltage: DC 12V/24V Auto
Charge/Discharge Current: 40A
Over Discharge Protection: 10.7V/21.4V
Charge Recovery Voltage: 12.6V/25.2V
Overcharge Floating Charge: 13.7V/27.4V
Equalization: Sealed – 14.4V / Gel – 14.2V / Flood – 14.6V

Easy Operation and Installation:

Wiring Steps: Turn the adjustment screw counter-clockwise until the plates move down. Insert the wire into the opening between the plate and the top of the terminal hole (not under it). Then, tighten the screw clockwise so the plate moves up and secures the wire.

Important Notes:

1. Keep the controller in a cool, well-ventilated place for proper heat dissipation.
   
2. This regulator is suitable only for lead-acid batteries (OPEN, AGM, GEL) and not for nickel hydride, lithium-ion, or other battery types.
   
3. Ensure the battery has enough voltage for the controller to recognize it before installation.
   
4. The working temperature range is -35°C to 60°C. During hot sunny days (when temperatures may reach 60–75°C), ensure the controller remains in a cool and ventilated area for stable performance.
