User Manual
Cause and corrective measure
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).
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.
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 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.
