The panel will start charging as
soon as the panel voltage is
higher
than
the
voltage.
The charge will resume as
soon as the light becomes
stronger.
Check if your panel is clean
and make sure none of the
cells are hidden.
Disconnect the solar panel
then check if the battery is not
in overvoltage or your
coupling voltage does not
exceed the accepted input
voltage of the solar charge
controller (12V/24V).
Check connections.
Make sure the power of the
panel/solar module is adapted.
Check connections (polarity
and connection).
