Description
3.2.7.2 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.

3.2.8 Interfaces
The inverter has the following interfaces for communication and remote monitoring:
• RS232 port
• RS485 interface
• S0 interface
You confi gure the interfaces in the Settings mode (see section 8.3 on page 36).
3.2.8.1 RS232 port
Use this monitoring option if you wish to manage system 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
9600 baud 8
The table below shows an example of a few lines of data transmitted over the RS232 interface.
