15.4 Messages concerning Active Power Limitation in the
System Logbook
Problem Cause and corrective measure
Message in the system logbook:
Supplied power has exceeded the
permitted value several times.
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, page68).
• 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 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 the system logbook:
Act. power limitation deactivated
due to incorr. configuration.
The function Limiting of the active power feed-in was
deactivated by SunnyHomeManager because the sys-
tem 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 Service (see Section16,
page142).
Message in the system logbook:
Disturbance:
act. power limitation activated w/
o regard to own consumption
The function Limiting of the active power feed-in is
faulty because there is no data from the feed-in meter. Risk
of yield loss because the self-consumption of the house-
hold cannot be taken into account.
Corrective measures:
• Ensure that the feed-in meter is working and
correctly connected.
