All BLUETOOTH devices in a PV system must have the same NetID. You can set a new NetID in the
inverter by means of the rotary switch C.
Figure 12: Positions of rotary switch C
Position Explanation
0 Communication via BLUETOOTH is deactivated.
1 Communication via BLUETOOTH with a further BLUETOOTH device
2 to F NetID for communication via BLUETOOTH with multiple BLUETOOTH devices
Procedure:
1.
Danger to life due to high voltages
• Ensure that the inverter is disconnected from all voltage sources (see Section10,
page57).
2. To set a new NetID, set the rotary switch C to the
determined NetID using a flat-blade screwdriver
(blade width: 2.5mm).
