Learn why your Renogy Wanderer shows a flashing green light and how to fix it.
A flashing green light typically indicates that the controller is in a state of searching for a power source or is not receiving adequate input.
Check the connections, ensure the solar panels are receiving sunlight, and verify the battery's state of charge.
The flashing green light typically signifies that the charge controller is in a state of alert, unable to initiate charging due to one or more faults in the system. This could stem from insufficient input voltage from the solar array, a ground fault condition, or a battery voltage that falls below the minimum threshold required for charging. The charge controller continuously monitors the input voltage and battery condition; if it detects anomalies, it will prevent charging to protect the battery and itself.
The Renogy Wanderer charge controller is showing a flashing green light, indicating that it is not charging the battery. Users may observe no increase in battery voltage despite sunlight exposure, and the monitoring app may report no charging activity.
Always consult a licensed electrician or certified solar installer when troubleshooting electrical components to ensure safety and compliance with local codes.
To avoid future occurrences, regularly inspect and maintain wiring connections, ensure the solar array is free from obstructions, and confirm that the charge controller settings are appropriate for the battery type. Additionally, consider installing a surge protector to safeguard against voltage spikes.
