Messages concerning Active Power Limitation in the System Logbook
Problem Cause and corrective measures
Message in the system
logbook: Fed-in power has
repeatedly exceeded the
permitted value Although the function Limitation of active power feed-in is
activated, more than the maximum permitted active power has
been fed into the utility grid.
Corrective measures:
• Ensure that the feed-in meter used complies with the
requirements (see the installation manual of the
Sunny Home Manager).
• Ensure that the feed-in meter is configured correctly
(see Section 8.6 "Configuring the Energy Meters",
page 55).
• 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.
• Ensure that the parameter Operating mode active
power is set to the value Active power limitation P via
system control for all inverters.
Message in system logbook:
Active power limitation
deactivated due to incorrect
configuration The function Limitation of active power feed-in has been
deactivated by the Sunny Home Manager because the system
configuration in Sunny Portal was faulty.
Corrective measures:
• This message can appear while making changes to the
Sunny Home Manager system, e.g. upon device
replacement. In this case, no action is needed.
• If the message appears over an extended time period,
contact the SMA Service Line.

Corrective measures:
• Ensure that the feed-in meter is working and correctly
connected.
