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
feed-in operation. Wait until the inverter switches to
feed-in operation.
The SMA Bluetooth Piggy-Back
is not correctly connected. Check for the correct positioning of
the SMA Bluetooth Piggy-Back on
the interface socket (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 can not register any
Bluetooth devices which are set
to NetID 1. Determine a free NetID, as
described in the Sunny Beam with
Bluetooth manual. 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.
