Maintenance
The following maintenance is recommended to be performed every three months.
1. Ensure all wire connections are sound and free from corrosion. Tighten terminal
block screws for both the solar array as well as the battery terminals.
2. Visually check the solar array and battery wiring for signs of overheating, damage,
and cracking. Replace any wires showing wear with new wires of the same gauge.
3. Verify each LED status to ensure match with specifications using a voltmeter.
Troubleshooting
Battery won’t charge:
• Solar panel may be sized incorrectly. A panel with a larger output is required. You may
add on to existing panels by wiring the additional in parallel with the existing panel.
• Usage may be too high. The battery is being drawn upon at a faster rate than the panel
is able to produce. A secondary battery may be used, by physically switching the
batteries out and allowing one battery to supply power while the other is being charged.
• Battery may be too small. In this case it may appear the battery is not charging however
it is the reserve that is depleting too quickly. A battery with a larger capacity may be
required. A secondary battery may be used, either by physically switching the batteries
out and allowing one battery to supply power while the other is being charged or using a
battery isolator. A second battery may also be added to the existing battery by wiring the
additional battery in parallel to the existing battery. The charge controller only needs to
be connected to one of the batteries in this case.
