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 Meter1.
• For feed-in meters, insert the four-pole plug into the pin connector Meter2.
• For PV production meters, insert the four-pole plug into the pin connector Meter3.
• 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 SunnyHomeManager to Energy Meters
with S0interface
Additionally required material (not included in the scope of delivery):
☐ A cable with at least two insulated conductors
Cable requirements:
☐ Conductor cross-section: 0.2mm
2
to 1.5mm
2
☐ Maximum cable length: 30m
Requirements for energy meters with S0interface:
☐ S0interface in accordance with DINEN62053-31, classA
☐ Bidirectional meters with an S0interface must be equipped with twoS0interfaces.
☐ Energy meters with an S0interface must output cumulative values of all line conductors at the
S0interface. If necessary, contact the manufacturer of the energy meter.
☐ Recommended pulse length: at least 20ms
☐ Recommended pulse rate: 1000 pulses per kWh
For the function Limitation of active power feed-in, energy meters with an S0interface
must have the following minimum pulse rates:
For systems with maximum permitted grid feed-in of more than 1500W:
at least 250pulses per kWh
For systems with maximum permitted grid feed-in of less than 1500W:
at least 500pulses per kWh
