Cause and corrective measures
It is possible that the NetID of the PV system is not set for
the new BLUETOOTH devices.
Corrective measures:
• Ensure that the NetID of the PV system is set for the
new BLUETOOTH devices.
• Ensure that NetID 1 is not set for the new
BLUETOOTH devices or on the
Sunny Home Manager.
The wireless connection of certain BLUETOOTH devices
may be disturbed by ambient conditions.
Corrective measures:
• Ensure that the connection quality for the
BLUETOOTH devices is at least "good" (see
BLUETOOTH device manuals).
• If the connection quality is not at least "good", use a
BLUETOOTH Repeater or SMA radio-controlled
socket. This will extend the wireless range of your
BLUETOOTH network.
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:
• Register within the operating time of the inverter.
The BLUETOOTH devices of your PV system may not be in
operation. In this case, the Sunny Home Manager cannot
establish a connection to these devices.
Corrective measures:
• Commission the BLUETOOTH devices.
