5. Inspection and Maintenance
It is highly recommended that each user inspect the charge controller at least once per year to
ensure longevity and optimal performance. Please follow this procedure:
1. Confirm that the correct battery type has been used.
2. Confirm that the current levels of the solar array and load do not exceed the controller
ratings.
3. Inspect for loose, broken, or burnt wire connections and replace them if needed. Make
sure all terminals are tightened.
4. Press the SET button until number 16 is displayed to verify the lights are working
properly.
5. Inspect for dirt, insects, and corrosion on the charge controller.
6. Check to make sure there is still enough space around the charge controller for
maximum airflow.
7. Check to make sure the charge controller functions and LED indicators are working
properly.
8. Make sure the PV array is clean and remove any debris.
9. Make sure all of the railings and PV bolts are tightened.
