2.3 Commissioning
Connect the solar inverter internally via
the ground cable (yellow-green) to the
cabinet cover. (See also Setup, step 7)
Put the cabinet cover on.
Screw it down tightly with the four
screws on the front.
Do not place any objects (e.g. this manu-
al) on the cabinet of the solarinverter.
Free ventilation behind the solar inverter
must be able to take place unimpeded.
If the unit is installed in the open air,
please take special care to ensure that the
screwed cable glands are properly sealed
and that the cabinet cover is precisely
located.
Switching the solar inverter on and off
· Switching on
When the solar inverter is mechanically
installed and connected to the electrical
cables, the unit can be commissioned as
follows:
Switch the grid connection on through
the external safety cutouts.
Switch the PV generator voltage on by
closing the PV generator switch. The solar
inverter will start up with adequate
PV power. If the PV input voltage is high
enough, the solar inverter will begin ope-
ration and feed the solar energy into the
electrical grid. You can see the operation
on the display. The current feed-in power
is shown here.
The solar inverter is supplied by the PV
generator. The solar inverter switches on
in the morning and off again in the eve-
ning. The relevant switching on and swit-
ching off thresholds are defined for the
PV generator. If the solar energy is not
sufficient to supply the electronics, several
switch-on attempts may have to be made
