6.6.2 Setting the Bluetooth NetID
Communication with a communication product via Bluetooth is activated by default. Networking with
other inverters via Bluetooth is deactivated by default.
The following configuration settings are possible via a rotary switch (switch C):
In order to restrict communication via Bluetooth between the inverters of your PV plant and those of
neighbouring systems, you can assign an individual NetID to the inverters of your PV plant
(switch position 2 to F). However, this is only necessary if neighbouring plants are situated within a
radius of 500 m.
For all inverters in your PV plant to be detected by your communication product, they must all have
the same NetID.
1. Disconnect the inverter from voltage sources and open it (see Section9.2 "Disconnecting the
Inverter from Voltage Sources", page64).
2. Set the arrow on the rotary switch (C) to the
required position with a screwdriver. Use a 2.5 mm
screwdriver for this purpose.
3. Close the inverter(see Section9.3 "Closing the
Inverter", page67).
