Modified on Tue, 17 Jun at 11:22 PM

⚠️ Issue 1: Solar Panel Not Charging the Battery


Possible Causes:


Insufficient sunlight exposure


Faulty charge controller


Loose or corroded connections


Battery issues


Troubleshooting Steps:


Ensure the panel is positioned in direct sunlight without obstructions.


Inspect and clean all wiring connections.


Use a multimeter to test the panel's voltage output.


Check the charge controller for faults or error indicators.


Test the battery independently to rule out battery-related issues.


⚠️ Issue 2: Solar Panel Not Producing Power

Possible Causes:


Shading on the panel


Loose or damaged wiring


Faulty bypass diodes


Internal cell damage


Troubleshooting Steps:


Ensure the panel is free from shade and obstructions.


Inspect all wiring and connections for damage or looseness.


Use a multimeter to test the panel's voltage output.


If issues persist, consult a professional technician.


⚠️ Issue 3: Low Power Output


Possible Causes:


High temperatures affect efficiency


Partial shading


Incorrect panel angle


Dirty panel surface


Troubleshooting Steps:


Ensure the panel is clean and free from debris.


Adjust the panel angle to optimise sunlight exposure.


Monitor the panel's temperature; excessive heat can reduce efficiency.


Check for any shading during different times of the day.


⚠️ Issue 4: Inverter Not Receiving Power


Possible Causes:


Faulty inverter


Incorrect wiring


Blown fuses


System voltage mismatch


Troubleshooting Steps:


Verify all wiring connections between the panel, charge controller, and inverter.


Check for blown fuses and replace if necessary.


Ensure the inverter is compatible with a 12V system.


Consult the inverter's manual for specific troubleshooting steps.


⚠️ Issue 5: Charge Controller Errors


Possible Causes:


Incorrect settings


Overload conditions


Faulty components


Troubleshooting Steps:


Reset the charge controller to its default settings.


Ensure the load connected does not exceed the controller's capacity.


Inspect for any visible damage or burnt components.


Refer to the controller's manual for error code interpretations.
