30A Solar Charge Controller Intelligent Battery Regulator for Lead Acid & Lithium Battery with LCD Display and 3A USB Port

This intelligent solar charge controller automatically manages the operation of solar panels and batteries, ensuring efficient power management and extended battery life. It protects your battery by automatically shutting down when the voltage drops below 8V, preventing over-discharge damage.

The controller is easy to install and operate. To wire it, loosen 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, and then tighten the screw clockwise to secure the wire. When installing, connect the system in the order of Battery → Load → PV Array, and disconnect it in reverse order.

Please follow the wiring instructions before setup, as the connection sequence is important. First, connect the battery, then the solar panel, and finally the load.

Important Notes:

Keep the controller in a cool and well-ventilated place to ensure proper heat dissipation. It is suitable only for lead-acid batteries (OPEN, AGM, GEL) and not for nickel hydride, lithium-ion, or other battery types. Ensure the battery has sufficient voltage for recognition before installation. The working temperature range is -35°C to 60°C, so during hot sunny days, ensure adequate ventilation to maintain performance.
