5. MAINTENANCE
Maintaining your solar charge controller is essential to ensure it operates efciently and effectively. We recommend following these maintenance
protocols once every six (6) months:
• Inspecting the controller: Check the charge controller regularly to see if it’s in good condition. Inspect the wires, terminals, and other parts for
damage or wear.
• Inspect the solar panels: Check the solar panels for damage or debris that can reduce their efciency. Keep them clean and clear of obstructions.
• Check the wiring: Inspect the wiring and connections regularly to ensure they’re in good condition and not loose or damaged.
• Keep the battery clean: Clean the battery terminals and connections regularly to prevent corrosion, which can affect the battery’s performance.
6. TROUBLESHOOTING
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.
6.1 PROBLEMS WITH 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 is in 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.
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.
Remedy:
Check the panel and to ensure it is not obscured. Clean the panel if it is dirty. Check that PV cables are connected to the controller.
