3.2.6 Mechanical components
3.2.6.1 DC isolator switch
There is one DC isolator switch inside the inverter housing. The DC isolator switch is used to disconnect the inverter
from the PV generator in order to carry out service.
Disconnecting the inverter from the PV generator
" Switch the DC isolator switches from 1 (ON) to 0 (OFF).
Connecting the inverter to the PV generator
" Switch the DC isolator switches from 0 (OFF) to 1 (ON).

3.2.6.2 Night start button
The unit switches off in the evening as nightfall approaches. At this point, nothing is shown on the display. In order
to retrieve the values from the current day (daily yield, daily hours of operation and max. feed-in power) after the
display switches off, the unit can also be activated during the night by pressing the night start-up button on the
underside of the inverter.

3.2.7 Interfaces
The inverter has the following interfaces for communication and remote monitoring:
• RS232 port
• RS485 interface
• S0 interface
• Digital input
You configure the interfaces in the Settings menu (see chapter 8.3 auf Seite 34).
3.2.7.1 RS232 port
Use this monitoring variant if you wish to manage operating data directly on a computer. The data can be processed
with standard spreadsheet programs.
The inverter and computer are connected with a serial 1:1 interface cable.
The cable length should not exceed 20 metres.
The data from the inverter is sent unidirectionally as pure ASCII text via the serial interface. The data is not checked
for errors.
The RS232 interface has the following parameters:
Baud rate Data bits Parity Stop bits Protocol
9600 baud 8 None 1 None
The table below shows an example of a few lines transferred via the RS232 interface
