7.3.5 Service menu
The following section describes the service menu items. Some items have password protection; see
also Fig. 9, p. 66.
You can obtain the password from our technical support department; see p. 80.
Caution
Risk of reduced yields. Inverter and grid parameters can be changed in the service menu. The
service menu may only be used by professional personnel who can ensure that the changes
do not contravene the applicable regulations and standards.
Power limiter
The inverter output power can be manually limited to a
minimum of 2000 W. When the power is manually limited,
the Derating symbol is shown in the status display and the

is displayed.
Fixed voltage
The device can regulate the input voltage to a manually ad-
justable value. This switches off the automatic setting of the
MPP (MPP tracking). The input voltage can be adjusted over a
range between the maximum and minimum input voltage.
Example of application: fuel cell
Caution
Before setting a fixed input voltage, make sure that
the generator is suitable for this. Otherwise, this may
result in yield losses or damage to the system.
Delete country setting
After the country setting has been deleted the device restarts
anew and displays the guided initial commissioning menu.
Factory setting
Resetting the device to the factory setting deletes the follow-
ing data:
• Yield data
• Event messages
• Date and time
• Country setting
• Display language
After the factory setting has been deleted, the device restarts
anew and displays the guided initial commissioning menu.
Voltage limits (peak value)
The following voltage limits can be changed:
• Upper voltage disconnection value 1)
• Lower voltage disconnection value 1) (fig. left)
1) The disconnection value relates to the peak value of the
voltage.
