2.4 Commissioning the Solar Inverter
Prior to starting up the Solar Inverter,
move the housing cover downwards by
releasing the lateral fixation on the right
lower side of the housing and pulling the
four lateral hexagon socket screws tight.
Do not deposit any objects (e. g. this
manual) on the housing of the Solar
Inverter. The ventilation behind the Solar
Inverter must not be obstructed.
If the device is installed outdoors, please
double-check that the cable glands, the
housing cover, and the protection cap of
the SUB-D9 connector (provided this ter-
minal is not allocated) are tight.
Starting-Up and Shutting-Down the
Solar Inverter
As soon as the Solar Inverter has been
mechanically installed and connected to
the power lines, it can be commissioned as
follows. Depending on whether or not you
are using DC main switches, the start-up
and shut-down sequence for the DC and
AC side differs.
Note: The Solar Inverter is supplied from
the grid. If the PV output is high enough,
the Solar Inverter will switch on autom
atically. For that purpose, on and off thres-
hold values have been determined.
Start-up (with DC main switch)
1. Switch the grid connection on with the
external automatic circuit breaker.
2. Switch the PV generator voltage on
by closing the DC main switch. If the
PV input voltage is sufficient, the Solar
Inverter will start and inject solar
energy into the electrical grid. The
injection is indicated by the power
pointer on the display.
