Load not operating properly
1. Press the TEST button to turn the lights on. This will assist in troubleshooting
the problem.
2. Check that the load is turned on. Check that no system fuses are defective.
Check that no system circuit breakers are tripped. Remember that there are
no fuses or circuit breakers inside the SunLight.
3. Check connections to the load, and other controller and battery connections.
Make sure voltage drops in the system wires are not too high.
4. Check for proper LED indications on the SunLight. If the red LOAD DISCON-
NECT LED is on, the load has been disconnected due to low battery voltage.
This is generally a normal state when the load exceeds the PV array output
due to weather and other sunlight conditions.
5. Check the PV array voltage under direct sun, with the array leads disconnect-
ed. The voltage should be close to the expected open circuit voltage for the
panel type used.
6. Visually inspect the PV array and verify that the array is clear of debris (e.g.
leaves, snow, dirt) and that it is oriented correctly for the installation location.
7. Measure the voltage at the controller BATTERY terminals. If this voltage is
above the LVD, the load should have power. Press the test button and then
measure the voltage at the controller LOAD terminals, and if there is no volt-
age present, the controller may be defective.
