Installation when not using the integrated measuring unit
If an SMA Energy Meter is installed at the grid-connection point and is not to be
replaced by the Sunny Home Manager 2.0, the Sunny Home Manager 2.0 can
also be operated without the measuring unit being enabled.
1. Connect the line conductor L1 and the neutral conductor to the voltage supply
of the Sunny Home Manager 2.0.
2. Select the SMA Energy Meter present as the purchased-electricity and feed-in
meter in Sunny Portal (see Section "Defining the Energy Meter at the Grid-Con-
nection Point").
Measuring the PV production power (single-phase / three-phase) up to
63 A
In PV systems with inverters from other manufacturers or hybrid systems with SMA
inverters, the integrated measuring unit can also be used for measuring the PV pro-
duction power. In this case there must already be an SMA Energy Meter installed
at the grid-connection point (see "Installation when not using the integrated measur-
ing unit").
1. Connect the Sunny Home Manager 2.0 to the common connection point of all
inverters in the household grid.
2. Select the Sunny Home Manager 2.0 as the PV production meter in Sunny Por-
tal (see Section "Defining the Energy Meter at the Grid-Connection Point").
The following figure shows a connection example in TN and TT grid configurations
in the case of installation at the grid-connection point. For exact connection specifi-
cations, contact your electric utility company.
Additionally required material (not included in the scope of delivery):
☐ 3 x current transformer
☐ Connection cables for current transformers
Procedure:
1. Connect one current transformer to each line conductor L1, L2 and L3.
2. On each current transformer, connect one connection cable for current measure-
ment to each of the secondary current terminals (k/S1 and l/S2). Observe the
permitted connection cross-section of the
Sunny Home Manager 2.0 (see Sec-
tion "Technical Data"):
3. Connect the connection cables for current measurement (dashed gray line) to
the Sunny Home Manager 2.0 . Observe the prescribed torque for screw termi-
nals (see Section "Technical Data").
4. Connect the connection cables for voltage measurement (solid gray line) to the
Sunny Home Manager 2.0 . Observe the prescribed torque for screw terminals
(see Section "Technical Data").
Connect the connection cables for voltage measurement to the corresponding line
conductors.
Additionally required material (not included in the scope of delivery):
☐ 1 x network cable
Recommended cable types:
• SF/UTP, S-FTP, S/UTP, SF/FTP, S/FTP, S-STP
Procedure:
1. Connect the network cable to the network terminal of the SunnyHomeManager
2.0.
2. Connect the other end of the network cable to a router / network switch.
Requirements:
☐ The PV system must be in operation.
☐ All devices must be in operation and connected to the
Sunny Home Manager 2.0 via a router / network switch.
☐ Devices that support the EEBus industry standard must be connected to the
Sunny Home Manager 2.0 (see technical information "SMA SMART HOME -
Home appliance energy management using EEBus").
☐ DHCP must be active for the router (see router manual).
Procedure:
1. Cover the Sunny Home Manager 2.0 with a cover or the contact protection of
the subdistribution.
2. Switch the power supply to the subdistribution back on.
☑ The LEDs on the Sunny Home Manager 2.0 light up during the startup proce -
dure. All devices in the local network will be recognized automatically.
3. Register all devices in Sunny Portal.
Sunny Portal serves as the user interface of the Sunny Home Manager 2.0. There-
fore, you must register the Sunny Home Manager 2.0 in Sunny Portal.

It is possible that the registration procedure was previously initiated but not complet-
ed.
• Reset the Sunny Home Manager 2.0 (see Section "Resetting the
Sunny Home Manager 2.0").
Procedure:
1. Remove all connected conductors from the Sunny Home Manager 2.0.
2. Remove the Sunny Home Manager 2.0 from the top-hat rail. To do so, tilt the the
lower edge of the Sunny Home Manager 2.0 forwards and lift the
Sunny Home Manager 2.0 off of the top-hat rail.
• Dispose of the Sunny Home Manager 2.0 in accordance with the locally appli-
cable disposal regulations for electronic waste.
The software licenses for the installed software modules are contained in the
Sunny Home Manager 2.0 software. Upon connecting the

lowing address: http://IP_address/legal_notices.txt.
The IP address (e.g. 192.168.1.120) will be assigned by your router for the
Sunny Home Manager 2.0.
You will find further information on determining the IP address in your router docu-
mentation.

NETWORK CONNECTION
Connecting Sunny Home Manager 2.0 via router / network switch
The Sunny Home Manager must be connected to the local network via a rout-
er / network switch. If the Sunny Home Manager 2.0 is connected directly to
an SMA inverter via network cable, the data will not be transmitted to the rout-
er.
IGMP protocol from version 2 must be supported
Data transmission with the Sunny Home Manager 2.0 works with multicasts.
In order for the Sunny Home Manager 2.0 to function correctly, all used net-
work components (router, network switch, power-line communication and
WLAN converter) must support at least IGMP protocol version 2 (IGMP V2)
(see manufacturer documentation).

Loss of data due to replacement or due to resetting to default settings
If the Sunny Home Manager 2.0 is reset to the default settings or replaced, all
data saved in the Sunny Home Manager 2.0 will be deleted. The data saved
in Sunny Portal can be transmitted to the Sunny Home Manager 2.0 after call-
ing up the PV system again in Sunny Portal. Devices that were connected to
the Sunny Home Manager 2.0 via EEBus must be reconnected (see technical
information "SMA SMART HOME - Home appliance energy management us-
ing EEBus").
