Troubleshooting



 Check all connections to ensure they are secure and clean

 Check polarity of the battery connection and make sure the battery generates at least 6V

 Ensure the solar panels are exposed to sufficient light – ideally position them to face the

sun directly

 If charge controller states that there is short-circuit, please ensure that the panels are

connected correctly, and that the wires at the terminals are not touching each other.

 If one of the status LED is off and a battery is connected, check that the battery terminals

have good connection and that the polarity is correct. Check that the voltage doesn’t

exceed the rated input voltage shown in Table 7-1 on Section 7.

 If the charge controller is not charging, ensure that the panel’s polarity, and check for loose

connections.

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

4. Make sure readings in the LEDs are consistent.

Fusing

Fusing is a recommended 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.
