Installation Guide
Cause
Parameters for the Bluetooth
communication were
changed.
Inverter with upgraded SMA
Bluetooth Piggy-Back is in
night mode.
The inverter has not been set
to the same NetID and
commissioned.
The set NetID is already
assigned by an external
Bluetooth PV plant.
The inverter with integrated
Bluetooth has an old
software package (only for
inverters SB 3000TL-20, SB
4000TL-20, SB 5000TL-20).
Rectification
When setting parameters that regulate the
Bluetooth connection (e.g. parameters for
the transmitting power and country
parameters), the communication via
Bluetooth is interrupted for some time
because the inverters are carrying out a
reboot of the communications interface.
This does not relate to inverters with
upgraded SMA Bluetooth Piggy-Backs.
• Wait until the inverter has completed
a restart. The inverter is then
accessible again.
• Wait until the inverter is again
working in normal operation. The
inverter is then accessible again.
• The inverter must be set to the NetID
of your PV plant and commissioned.
Contact your installer.
• You must assign the PV plant a free
NetID. Contact your installer.
• Update the software package
version of your inverter to a version
higher than 2.0.
