5.3.5 Communication via Bluetooth
Communication via Bluetooth with a communication device is activated as standard. Networking via
Bluetooth with other inverters is deactivated ex works.
The following configuration settings are possible via a rotary switch (switch C):
In order to restrict communication via Bluetooth between the inverters of your system and those of
neighboring systems, you can assign an individual NetID to the inverters of your system (switch
position 2 … F). This, however, is only necessary if neighboring systems are within a radius of 500 m.
So that all inverters in your PV system are detected by your communication device, all inverters must
have the same NetID.
Procedure
1. Open the Quick Module, as described in section 5.3.3”Opening the Quick Module”
(page28).
2. Set the arrow on the rotary switch (C) to the
required position using a screwdriver. The width of
the screwdriver should be 2.5 mm.
