26 Start-up and operation
Make sure that there is sufficient light for the inverter to be able to feed power to the AC power system
(grid).
There must be enough light so that the solar generator is able to feed power to the inverter. This allows
you to make sure that the inverter operates correctly. You can set the parameters when there is no light
on the PV arrays. You can do a test of the inverter modulation without power from the photovoltaic
arrays.
Measure that the polarity of all DC inputs is correct.
Make sure that the open circuit DC voltage from the solar generator is in the correct range for the
inverter.
You can make an estimate of the expected DC voltage: Use the open circuit voltage of the solar
modules and the number of modules in a string.

Set up the insulation monitoring device
Make sure that there is only one insulation monitoring for the inverter in the same galvanically
connected IT system. Each inverter has one insulation monitoring device.
Make sure that the settings of the insulation monitoring device are suitable for the installation and obey
the local regulations. The trip limit is adjusted to 3 kohm at the factory.

Set-up the current transducers (G417) for all DC inputs
Adjust monitoring settings for DC current measurements.
Refer to the firmware manual.

Hints on using the assistant control panel

Parameter settings before the first start
Make the parameter settings needed before the first start according to the firmware manual.
Refer to the start-up section of the firmware manual.

First start (local control mode)
Disable the external communications, for example, for the data logger, plant controller or SCADA
system.
Release the fast power off switch.
Make sure that the DC voltage of the solar generator matches the value of the 208.01 DC Input Voltage
parameter. If there is a mismatch of the voltages, do not start the inverter. Contact your local FIMER
representative.
Close the optional AC breaker (+F296), set parameter 214.02 to “Close”.
Verify the AC voltage from parameters 190.06 to 190.08. If the AC voltage differs from the grid value, do
not start the inverter. Contact your local FIMER representative.
Check the insulation level of the PV system measured by MIRU, see parameter 210.29.
Units with functional grounding (negative as standard, positive as an F283): Force grounding
from parameter 210.01. Verify the grounding current from parameter 210.14.
If faults or warnings occur, refer to the
Firmware manual .
Set the grid code according to the local requirements.
Refer to the
Firmware manual .
The two commands at the bottom of the display (in the figure on the right,
Options and Menu), show the functions of the two softkeys
and located below the display.
The commands assigned to the softkeys vary depending on the context.
Use keys , , and to move the cursor and/or change values
depending on the active view.
Key shows a context-sensitive help page.
