14.0 Troubleshooting Problems
How to Read this Section
Troubleshooting Problems is split into three sub-sections, grouped by symptoms
involving key components. 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.
14.1 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:
Check the voltage at the controller battery terminals with a voltmeter and
compare with a voltage reading at the battery terminals.
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.
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.
Display Reading: Nighttime
Time of Day: Daytime
Possible Causes:
Panel is covered by something; PV panel is too dirty to supply a high enough
voltage to charge the battery; PV panel is not connected.
