PROBLEM
POSSIBLE CAUSE
POSSIBLE SOLUTION
Solar panel is exposed to
sunlight but the charging
indicator on the regulator is
not lit.
Battery is not properly
connected to the regulator
or the regulator is not
properly connection to the
panel, or the sunlight is too
weak.
1. Check all connections to make
sure the regulator is properly
connected to both the battery and the
panel.
2. Wait until the sun shines more
brightly or the weather condition
improves.
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 on
regulator flashes no output.
The battery is over-
discharged.
Disconnect the load from the battery
and charge the battery for a longer
period of time.
There is no voltage output
reading from the panel.
The output cables may not
be connected correctly.
Verify that the output cables are
connected to the battery correctly.
The charge indicator on the
regulator doesn’t come on.
Battery voltage is too low.
Battery fuse is blown (if
applicable).
Check the battery voltage. If the
battery voltage is too low (often 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 the level specified for that
controller.
