Data on the following pages is
not up to date:
• Current status and
forecast
• Energy balance on the
Current tab
• Load balance and
control on the Current
tab
Settings in the router prevent Sunny Portal from requesting current
data from the Sunny Home Manager.
Corrective measures:
• Ensure that the following requirements are fulfilled.
– All UDP ports > 1024 on the router or modem must be
open for outgoing connections. If there is a firewall
installed on the router or modem, you may need to
adjust the firewall rules.
– It must be possible for the outgoing router or modem
connections to reach all Internet destinations (target IP,
target port). If there is a firewall installed on the router
or modem, you may need to adjust the firewall rules.
– On a router or modem with NAT (Network Address
Translation), no port forwarding should be set up.
This will help prevent potential communication
problems.
– There must be no packet filtering or manipulation for SIP
packets installed on the router or modem.
An exclamation mark is
permanently displayed after
parameters have been
changed. Sunny Portal could not transfer the parameters to the Sunny Home
Manager.
Corrective measures:
• Ensure that the connection between the
Sunny Home Manager and Sunny Portal is established
(see the installation manual of the Sunny Home Manager).
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 S0 interface must output values netted across
the line phases at the S0 interface.
Corrective measures:
• Ensure that the energy meter with S0 interface is outputting
values which are netted across the line phases. If necessary,
contact the manufacturer of the energy meter.
