When Solar Power is weak as well as during the night the charger will turn off the charging LED,
indicating that charging status has been shut off in order to prevent the current back float to the solar
panel. Back Float of current may cause serious damage to the panel.
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.
Visual check of 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 need only be connected to one of the batteries in this
case.
•
The battery may be bad. Small level of charge or discharge will greatly affect the battery
voltage. Battery needs replacing.
•
Wires may be incorrectly hooked to the charge controller. Ensure the wires are connected in
parallel to the controller and to the correct terminals.
Solar Panel has no output:
•
The solar panel may be seriously affected by the angle of the panel with regards to the sun, and
environmental factors. Ensure the surface is clean and free of dust and build up; a clean damp
rag may be used to clear the panel of dust. Do not use soap or solvents of any kind. Cloudy
conditions will affect the output of the solar panel.
•
Wires may be incorrectly hooked to the charge controller. Ensure the wires are connected in
parallel to the controller and to the correct terminals. Please refer to the Connection Procedures
portion of this manual.
