12.0 Troubleshooting Problems

How to Read this Section

Troubleshooting Problems is split into three sub-sections, grouped by

symptoms involving key components. Components considered irrelevant

in a diagnosis are denoted ‘Not Applicable’ (N/A). A multimeter or

voltmeter may be required for some procedures listed.

It is imperative all electrical precautions stated in the Warning Section

and outlined in the Installation Section are followed. Even if it appears

the system is not functioning, it should be treated as a fully functioning

system generating live power.

12.1 Problems with the Display

Display Reading: Blank

Time of Day: Daytime/Nighttime

Possible Causes:

Battery or fuse connection and/or solar array connection

(Daytime only) or battery or fuse connection (Nighttime only).

How to tell:

1. Check the voltage at the controller battery terminals with a

voltmeter and compare with a voltage reading at the battery

terminals.

2. If there is no voltage reading at the controller battery terminals,

the problem could be a fuse, or the wiring between the battery

and the controller. If the battery voltage is lower than 6 volts the

controller will not function.

3. For the solar array, repeat steps 1 and 2 substituting all battery

terminals with solar array terminals.

Remedy:

Check all connections from the controller to the battery including

checking for correct wire polarity. Check that all connections are clean,

tight, and secure. Ensure the battery voltage is above 6 volts.
