Sunny WebBox is
unable to detect
devices connected to
the RS485 bus. The data transmission protocol
and the baud rate are not
configured properly. Make sure the data transmission
protocol and the baud rate for the
connected devices are configured
properly (see section 10.2.1 ”Setting
SMA-COM” (page 61)).
Check the cabling of the devices on the
RS485 communication bus. Refer to the
RS485 cabling diagram for information
on how the cables should be connected
to the RS485 communication bus.
Make sure the RS485 cable is properly
connected to the Sunny WebBox. Check
all connections (see section
6.8.2 ”Connecting the Sunny WebBox
to the RS485 Communication Bus”
(page 37)).
Check the termination and signal biasing
of the RS485 communication bus
(see section 6.8.2 ”Connecting the
Sunny WebBox to the RS485
Communication Bus” (page 37)).
The Sunny WebBox will
not transmit data to
Sunny Portal. Data transmission is
deactivated. Configure data transmission to the
Sunny Portal (see section
9.2.1 ”Registering Sunny WebBox in
Sunny Portal” (page 51)).
Check the specified plant name and
e-mail address. You may need to register
an account on the Sunny Portal again.
