6.5 Communication
6.5.1 Bluetooth
Bluetooth communication with a communication device is activated by default. Bluetooth
networking with other inverters is deactivated ex works (switch position 1 is the condition on
delivery). Bluetooth communication is set using a rotary switch inside the Sunny Boy.
The following settings can be made for the rotary switch:
In order to distinguish the inverters of your system from those of adjacent systems for Bluetooth
communication, you can assign an individual Bluetooth ID for the inverters in your system (switch
setting 2 ... F). However, this is only necessary if the adjacent system is within 500 m of your system.
All inverters in your system must have the same Bluetooth ID to ensure that they are registered by
your communication device.
To do so, proceed as follows:
1. Open the Sunny Boy as described in section 8.1 „Opening the Sunny Boy” (Page 49).
2. Set the arrow on the right rotary switch to the
required position using a screwdriver (2.5 mm).
3. Close the Sunny Boy as described in section 8.2
„Closing the Sunny Boy” (Page 51).
