8. Connect the end of the cable to the energy meter. Observe the polarity of the insulated
conductors.
9. Use the labels provided to mark each cable with the pin connector and energy meter to which
it is assigned.
10. Make a note of the S0 pulses per kWh of each energy meter. This will facilitate the meter
configuration in Sunny Portal.

Replacing Energy Meters
1. Decommission the energy meter to be replaced (see energy meter documentation).
2. When replacing the SMA Energy Meter, make a note of the serial number of the new SMA
Energy Meter. The serial number is to be found on the type label of the SMA Energy Meter.
3. When replacing the SMA Energy Meter, or if the new energy meter with S0 interface has a
different pulse rate to the old energy meter with S0 interface, configure the new energy meter
in Sunny Portal (see the user manual "Sunny Home Manager in Sunny Portal").

Connecting the Sunny Home Manager to the Router
1. Connect the network cable to the network
terminal of the Sunny Home Manager. When
using a different network cable to that supplied
with the delivery, the cable must be suitable for
connection to the Sunny Home Manager (for
cable requirements, (see Section 4.1.4 "System
Requirements", page 27)).
2. Connect the other end of the network cable to the router.

Connecting a Smart Appliance
Some modern household devices have an Ethernet connection with which the data of the device
can be called up via the local network. If there is an Internet connection via the network router, the
manufacturers of household devices can use this data for maintenance purposes, for example.
Visualization and control of the household devices via mobile devices (e.g. via app in the
Smartphone) is also possible with this. If the manufacturer of the networked household devices, in
cooperation with SMA Solar Technology AG, has implemented a special data exchange protocol
for energy management in the device control (for information on supported products, see Section
Section 2.3, page 12), the Sunny Home Manager can control these loads directly via the local
network. The smart appliances send information on the load type, the planned energy requirement,
and the preferred operating time period to the Sunny Home Manager. The Sunny Home Manager
factors this information into its load control, and also taking the configured optimization targets in
the context of load control into account, sends appropriate start and stop signals to the loads.
Requirements:
☐ The device must support the data exchange protocol defined by SMA Solar Technology AG.
☐ The Sunny Home Manager must be located in the same local network as the device.
