Consult an installer if the problem remains while irradiation of
the PV modules is sufficient.
Select the correct country code. See section 4.3.2.
Maybe the air flow of the Sunmaster is obstructed. See chapter

an installer
Contact your supplier.
Check the connection to the AC-grid. Check the fuse in the
meter cupboard.
