To fix your solar charge controller, follow these steps:
1. Make sure your solar panels are receiving adequate sunlight. Remove any shading caused by trees or nearby buildings.
2. Check the connections between the solar panels, charge controller, and batteries. Ensure all cables are securely plugged in.
3. Inspect the charge controller for any visible damage or loose wires. Tighten any loose connections.
4. Reset the charge controller by disconnecting it from the battery and solar panels for a few minutes, then reconnecting them.
5. Test the voltage output of the solar panels and battery using a multimeter. If the readings are not within the recommended range, the charge controller may need to be replaced.
Remember to always consult the manufacturer's instructions and seek professional assistance if needed.
