Problem Cause and corrective measure
SunnyPortal is displaying unrealistic
data.
The energy meters are connected to the wrong connection
ports of the SunnyHomeManager.
Corrective measures:
• Ensure that each energy meter is connected to the
connection port assigned to that energy meter (see
the installation manual of the
SunnyHomeManager).
In the diagrams Energy balance -
Current and Energy balance - Day,
unrealistic values are displayed for
feed-in and purchased electricity.
Energy meters with an S0interface must output values net-
ted via the line conductors at the S0interface.
Corrective measures:
• Ensure that the energy meter with S0 interface is
outputting values which are netted via the line
conductors. If necessary, contact the manufacturer of
the energy meter.
SunnyPortal is not showing any
weather forecast in the diagram Fore-
cast and recommended action.
It can take up to 24 hours after the SunnyHomeManager
has been initially registered in SunnyPortal until the
weather forecast is displayed.
Corrective measures:
• After 24 hours, check again to see whether the
weather forecast is displayed.
• If after 24hours there is still no weather forecast
displayed, contact the Service team (see Section16,
page142).
The animated graphic on the page
Current status and Forecast is not
displaying any current data.
The reception of current data from the SunnyHomeMan-
ager is only possible if the data request interval is set to
Automatic.
Corrective measures:
• Set the data request interval to Automatic (see
Section8.7, page69).
It is possible that no PV production meter is connected to
the SunnyHomeManager and that too many data cap-
ture devices (e.g. SunnyBeam and several computers with
SunnyExplorer) are simultaneously accessing the devices
of your PV system.
Corrective measures:
• Ensure that, apart from the SunnyHomeManager, a
maximum of two other data capture devices are
accessing your system at any one time.
