Rectification
• Set the NetID of the PV plant
(see section 6.2 "Configuring
Bluetooth Settings for the Sunny

or use an SMA Bluetooth Repeater
in order to extend the radio range.
Repeat the commissioning
(see page 25).
• Remove a Master and repeat the
commissioning process
(see page 25).
• Change the position of the Sunny
WebBox in order to set up a
connection via another device in the
plant or remove one master from the
plant. Further information on
SMA Bluetooth can be found in the
download section at

• Wait until the Sunny WebBox has
automatically re-established the
connection.
