2.4 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 mounted outdoors, please
ensure proper sealing of the threaded
cable glands and precise positioning of
the housing cover as well as the protecti-
ve cover of the SUB-D connector, if this
connection is not configured.
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 grid.
With adequate PV output, the solar inver-
ter switches on automatically. Appropriate
switch-on and switch-off thresholds are
fixed for this purpose.
