in cloudy weather. This is normal, and does
not affect either the yield or the mode of
functioning of the solar inverter.
· Switching off
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
removing the TYCO SOLARLOK connectors
must never be performed under load. In
the event of non-compliance, the connec-
tors could be damaged by a strong electric
arc. In this case, the relevant connectors
must be replaced!
Remove the cabinet cover.
Check that the grid connection terminals
are voltage-free.
