Maintenance
For best controller performance, it is recommended that these tasks be performed from time to
time.
1. Check that controller is mounted in a clean, dry, and ventilated area.
2. Check wiring going into the charge controller and make sure there is no wire damage or
wear.
3. Tighten all terminals and inspect any loose, broken, or burnt up connections
Fusing
Fusing is a recommendation in PV systems to provide a safety measure for connections going
from panel to controller and controller to battery. Remember to always use the recommended
wire gauge size based on the PV system and the controller.
