Message in system logbook:
0 W feed-in measured
continuously. If meter is
faulty, no active power
limitation possible.
The S0 feed-in meter has not provided any feed-in data for
24 hours, i.e., a feed-in reading of 0 W was measured.
This may indicate a fault in the S0 feed-in meter. If the S0 feed-in
meter is defective, the function Limitation of active power
feed-in cannot be activated.
Corrective measures:
• Make sure that the S0 feed-in meter is working and correctly
connected.
• If you are aware that no feed-in has taken place, e.g.,
if there is snow on the PV modules, then you can ignore this
message.
Message in the system
logbook: Inverter is not
responding to active power
limitation
At least one inverter is not responding to the prompt to limit the
active power feed-in.
In this case, the Sunny Home Manager initiates stronger active
power limitation in the remaining inverters. Consequently,
the maximum permitted active power feed-in is complied with.
If the message Fed-in power has repeatedly exceeded the
permitted value appears on the same day, an error is present.
Corrective measures:
• Ensure that the parameter Operating mode active
power is set to the value Active power limitation P via
system control for all inverters.
• Ensure that the BLUETOOTH connection between all the
devices in the system is good. You can check the connection
quality with Sunny Explorer (see Sunny Explorer user
manual). If necessary, use the SMA radio-controlled socket
as a repeater.
