Voltima – SunCase Plus 31
Troubleshooting
If the battery does not charge even though the solar panel is facing directly towards the sun,
this may indicate a problem in the connections.
Make sure that the solar module is connected correctly and that no connections are reversed.
Also, the solar charge controller may be damaged. In this case, it must be replaced.
Note!
Always read and follow the operating instructions of the solar charge controller that you
connect to the solar module.
