SMA sunny home manager - Connecting the Sunny Home Manager to Energy Meters with S0 Interface

2. Connect the plug of the optical probe to the pin
connector to which the corresponding energy
meter is assigned. Insert the four-pole plug into
the upper pin row:
• For purchased electricity meters, insert the four-pole plug into the pin connector Meter1.
• For feed-in meters, insert the four-pole plug into the pin connector Meter2.
• For PV production meters, insert the four-pole plug into the pin connector Meter3.
• For bidirectional meters for grid feed-in and purchased electricity, insert the four-pole
plug into the pin connector Meter 1.
3. Use the labels provided to mark each cable with the pin connector and energy meter to which
it is assigned.
7.2.3 Connecting the SunnyHomeManager to Energy Meters
with S0interface
Additionally required material (not included in the scope of delivery):
☐ A cable with at least two insulated conductors
Cable requirements:
☐ Conductor cross-section: 0.2mm
2
 to 1.5mm
2
☐ Maximum cable length: 30m
Requirements for energy meters with S0interface:
☐ S0interface in accordance with DINEN62053-31, classA
☐ Bidirectional meters with an S0interface must be equipped with twoS0interfaces.
☐ Energy meters with an S0interface must output cumulative values of all line conductors at the
S0interface. If necessary, contact the manufacturer of the energy meter.
☐ Recommended pulse length: at least 20ms
☐ Recommended pulse rate: 1000 pulses per kWh
For the function Limitation of active power feed-in, energy meters with an S0interface
must have the following minimum pulse rates:
For systems with maximum permitted grid feed-in of more than 1500W:
at least 250pulses per kWh
For systems with maximum permitted grid feed-in of less than 1500W:
at least 500pulses per kWh
