Technical Specifications

For best controller performance, it is recommended that these tasks be performed from time to time.

1. Check wiring going into the charge controller and make sure there is no wire damage or wear.

2. Tighten all terminals and inspect any loose, broken, or burnt up connections

3. Occasionally clean the case using a damp cloth

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.
