Risk of Electric Shock! Make sure that all power is turned off before touching the
terminals on the charge controller.
For best controller performance, it is recommended that these tasks be performed from time to time.
I . Check that controller
2. Check wiring going into the charge controller and make sure there is no wire damage or wear.
3. Tighten all terminals
4. Make sure LED readings
5. Check to make sure none of the terminals have any corrosion, insulation damage, high
temperature, or any burnt/discoloration
Fusing is recommended in PV systems to provide a safety measure for connections going from
panel to controller and controller to battery. Remember
gauge size based on the PV system and the controller.
