System ON / OFF
The solar module can be switched ON and OFF with the
ON / OFF pushbutton.
To prevent the system being switched OFF accidentally, the
pushbuttonneedstobehelddownforatleast3secondstoeffect

In the shutdown state, no protective functions are enabled
(except anti-seizing pump protection).
