5.6 Starting up the inverter
After completing the mechanical and electrical installation,
the inverter is put into operation as follows:
During the initial start-up, the appropriate country and
language must be selected.
The green “PV-Generator” LED lights up when in non-grid-
feed mode and indicates that it is ready to be put into opera-
tion. The display now indicates the current generator voltage
“Start from xxx V, Measured: xxx V”. If the measured voltage
is greater than the starting voltage, the unit will start the grid-
feed after a country-specifi c waiting time. This start-up period
is required in order to ensure that the generator voltage is
continuously above the power delivery limit of 200 V. A quick
start routine is provided for start-up and test purposes. This
routine circumvents the start-up period. This quick start
routine is found in the confi guration mode menu (see Oper-
ating Instructions).
During the normal start-up procedure, the line relays audibly
switch on after a country-specifi c time period and the grid-
feed starts. This is indicated by the green LED “Grid-feed”. The
display now shows the power being fed into the grid. The
“Display” key can now be used to display the various meas-
ured values (see Operating Instructions).

NOTE
The inverter can only be put into operation under daylight
conditions (i.e. when the solar generator voltage is
present). If no daylight or solar generator voltage is
present, the inverter can be activated by pressing the
night start-up key (see section 4.8 in the Operating
Instructions). However, normal operation is not possible
in this condition. Only the values can be read off the
display.
ACTION
–
Switch on the line voltage (via the external circuit
breakers).
–
Switch on the solar generator via the DC disconnector
(0
→
1).
Wrong parameter settings can lead to loss of
functionality as well as render your safety certifi -
cate [“Unbedenklichkeitsbescheinigung”] invalid.
Modifi cations may only be made in exceptional
cases and after prior consultation with the manu-
facturer and power supply company.

ACTION
To switch to programming mode, hold down key “2” for
approx. 20 seconds. Use key “1” to scroll through the vari-
ous menu items. The menu is continuous. When you reach
the end, the display automatically returns to the fi rst item.
ACTION
Use the “Settings” key to change the parameter that is
shown. The value then either increases or decreases,
depending on the parameter. The values here are also
continuous, i.e. after you reach the maximum value, they
return to the minimum value.
