Setup and Installation
Follow these steps to correctly set up your SOLPERK solar panel charger kit:
- Step 1: Connect the Controller and Solar Panel. Connect the solar panel to the MPPT charge controller. Ensure the connections are secure. When the solar panel receives direct sunlight, a blue indicator light on the controller will illuminate.
- Step 2: Connect the Battery. Connect the 12V battery to the MPPT charge controller. Once connected, a red indicator light on the controller will illuminate, indicating that the battery is charging. When the battery is fully charged, the red light will turn off, and a green indicator light will illuminate.

The kit includes a 360° adjustable mounting bracket, allowing you to position the panel at the optimal angle for maximum sun exposure. It can be mounted on the ground, wall, or roof.
Operating Instructions
The MPPT charge controller features three LED indicator lights to provide real-time status of the charging process:
- Blue Light: Indicates that the solar panels are connected and receiving sunlight.
- Red Light: Indicates that the battery is currently charging.
- Green Light: Indicates that the battery charging process is completed.

Maintenance
Proper maintenance ensures the longevity and optimal performance of your solar panel charger kit:
- Panel Cleaning: Regularly clean the surface of the solar panel with a soft, damp cloth to remove dust, dirt, and debris. A clean panel ensures maximum sunlight absorption and efficiency.
- Obstruction-Free: Ensure the solar panel receives direct sunlight without any obstructions (e.g., tree branches, shadows from buildings).
- Connection Checks: Periodically inspect all electrical connections for tightness and corrosion. Loose or corroded connections can reduce efficiency and pose safety risks.
- Weather Exposure: While the controller is waterproof, avoid prolonged exposure of the entire unit to extreme weather conditions when possible, as this may reduce its overall lifespan.
- Battery Condition: This charger is designed for charging and maintaining batteries. It is not intended for charging completely depleted or severely damaged batteries.
Troubleshooting
If you encounter issues with your SOLPERK solar panel charger kit, refer to the following common troubleshooting steps:
- No Blue Light on Controller:
- Ensure the solar panel is connected correctly to the controller.
- Verify the solar panel is exposed to direct sunlight.
- Check for any damage to the solar panel or wiring.
- No Red Light (Battery Not Charging):
- Confirm the battery is properly connected to the controller.
- Check the battery voltage; if it's extremely low, the controller might not initiate charging.
- Ensure the blue light is on, indicating solar input.
- Green Light Not Illuminating (Battery Not Fully Charged):
- Allow sufficient time for charging, especially for larger batteries or on cloudy days.
- Ensure the solar panel is receiving optimal sunlight.
- Check the battery's health; an old or damaged battery may not reach full charge.
- Reduced Charging Efficiency:
- Clean the solar panel surface.
- Adjust the panel angle to face the sun directly.
- Check for partial shading on the panel.
