in cloudy weather. This is normal, and does not affect either the yield or the mode of functioning of the solar inverter.

Disconnect the PV generator side first by opening the PV generator switch, and then the grid connection by isolating the relevant mains fuse.

If your PV system does not have a PV generator switch, you must disconnect the grid connection first of all by isolating the relevant mains fuse. When you do this, a "grid error" will be entered in the error memory of the solar inverter.

If the solar inverter is to be completely disconnected (e.g. removal) from the PV system, reconfigured or extended, the cabinet cover must be removed. Pay heed to all safety hints (Pages 90 and 91).

!

Open the main switch for the PV DC voltage and the mains fuse as described above. After a waiting period of at least five minutes, the solar inverter will be voltage-free.

Disconnection of the PV generator by

must never be performed under load. In

 

the event of non-compliance, the connec-

arc. In this case, the relevant connectors

 

must be replaced!

 

Remove the cabinet cover.

 

Check that the grid connection terminals

 

are voltage-free.
