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.
