Sunny Beam / Sunny
Explorer does not establish
a connection to the inverter
(with SMA Bluetooth Piggy-
Back). The inverter (with SMA
Bluetooth Piggy-Back) has not
been commissioned.
Commission the inverter as
described in the inverter manual.
The inverter (with SMA
Bluetooth Piggy-Back) is not in
feeding operation.
Wait until the inverter switches to
feeding operation.
The SMA Bluetooth Piggy-Back
is not correctly connected. Check if the SMA Bluetooth Piggy-
Back is correctly placed on the
interface port (see Section 4.2)
The NetID is set to 0. Set the NetID of your PV system (see
Section 4.3).
The Sunny Beam with Bluetooth
and the SMA Bluetooth
Repeater cannot register any
Bluetooth devices which are set
to NetID 1.
Determine a free NetID, as
described in the manual for Sunny
Beam with Bluetooth. Only NetIDs
from 2 to 9 and from A to F are
possible. Set your PV system to the
determined NetID (see section 4.3).
The Net ID is set to a different
NetID than the NetID of the PV
system. Set the NetID of your PV system (see
section 4.3).
The connection quality is
unreliable or critical. Change the position of your devices
in relation to one another in order to
shorten the radio link. If that is not
possible install the SMA Bluetooth
Repeater, in order to close the radio
gap. For a higher range you can also
use the SMA Bluetooth Piggy-Back
Plus with antenna.
The connection between the
inverter (with SMA
Bluetooth Piggy-Back) and
the communication device
often breaks off.

The update is not
completed. Power output to the grid is less
than 50 W. Only perform the update if the
inverter has a sufficient power output
to the grid of at least 50 W.
