SOLAR PANEL TROUBLESHOOTING
PROBLEM
POSSIBLE CAUSE
POSSIBLE SOLUTION
Solar panel is exposed to
sunlight but the charging
indicator is not lit.
Battery is not properly connected
to the solar panel or the sunlight
is too weak.
1. Check all connections to make sure
the solar panel is properly connected to
the battery.
2. Wait until the sun shines more
brightly or the weather condition
imporves.
Without load, battery
indicators stay at the same
level even after charging for
a long period of time.
The battery is damaged or has
died and no longer holds an
adequate charge.
Replace the battery.
Battery indicator flashes no
output.
The battery is over-discharged.
Disconnect the load from the battery
and charge the battery for a longer
period of time.
LED indicators randomly
flash.
The battery is not properly
connected.
Disconnect the battery and remove all
the cables from the solar panel and the
battery, repeat set-up procedure shown
on page 7.
There is no voltage output
reading from the panel
The output cables may not be
connected correctly.
Verify that the output cables are con-
nected to the battery correctly.
The panel is fitted with a SMART control-
ler that will not allow any output if the
panel is not connected. This protects
the panel.
The charge LED doesn’t glow
green.
Battery voltage is too low.
Battery fuse is blown.
Check the battery voltage. If the battery
voltage is less than 8V, the controller
will not work.
Check the fuse. The fuse will typically be
blown for the following reasons:
1. Battery poles +/- are reversed or a
short circuit occurred.
2. Solar controller output current over
10A.
