Cause and corrective measure
Inverters with BLUETOOTH Piggy-Back shut down
overnight. For this reason, the Sunny Home Manager can-
not establish a connection to these inverters during this
time.
Corrective measures:
• Select [Skip forward] and continue with
registration. Upon registration, add the devices to
the system as new devices when there is sufficient
irradiation (see the user manual
"Sunny Home Manager in Sunny Portal").
The devices of your PV system may not be commissioned.
In this case, the Sunny Home Manager cannot establish a
connection to these devices.
Corrective measures:
• Commission the devices.
Insufficient radio range of the inverter with BLUETOOTH
communication interface.
Corrective measures:
Use an SMA BLUETOOTH Repeater or SMA radio-con-
trolled socket. This will extend the wireless range of your
BLUETOOTH network.
Insufficient transmission power of the inverter with
SMA BLUETOOTH Piggy‑Back Plus.
Corrective measures:
Use the antenna extension add-on kit "ANTEXTKIT25-10".
The Sunny Home Manager is too far from your system or
the BLUETOOTH connection is disturbed. This could be
due to walls or ceilings that absorb the radio waves.
Corrective measures:
• Mount the Sunny Home Manager closer to a device
in your system. If this is not possible, use an
SMA BLUETOOTH Repeater,
SMA BLUETOOTH Repeater Outdoor or
SMA radio-controlled socket with BLUETOOTH. This
bridges the dead zone.
