The inverter is equipped with
Bluetooth
communication as standard. Additionally, it features
Speedwire communication with Webconnect function.
The inverter can communicate with special SMA communication products and other inverters via
Bluetooth
(see Section 7.4 "Setting the NetID", page 57).
If you would like to communicate via
Bluetooth
, you can protect the inverter with a plant password

All inverters are delivered with a standard plant password for the user (0000) and a standard plant
password for the installer (1111). To protect the plant from unauthorised access, you must change
the plant passwords using Sunny Explorer (for information on changing the plant password, refer to
the Sunny Explorer help).
