7.2.2 Connecting Sunny Home Manager to Energy Meter with S0
Interface
Additional required material (not included in scope of delivery):
☐ A cable with at least two insulated conductors
Cable requirements:
☐ Conductor cross-section: 0.2 mm
☐ Maximum cable length: 30 m
Requirements for energy meters with an S0 interface:
☐ S0 interface in accordance with DIN EN 62053-31 class A
☐ Bidirectional meters with an S0 interface must use two S0 interfaces.
☐ Energy meters with an S0 interface must output balanced values at the S0 interface via the line
conductors. If necessary, contact the manufacturer of the energy meter.
☐ Recommended pulse length: at least 20 ms
☐ Recommended pulse length: 1,000 pulses per kWh. For the "limiting of the active power feed-in"
function, energy meters with an S0 interface must have the following pulse rates:
– For plants with a maximum allowed feed-in of more than 1,500 W:
at least 250 pulses per kWh
– For plants with a maximum allowed feed-in of less than 1,500 W:
at least 500 pulses per kWh
1. Remove 4 cm of cable sheath.
2. Shorten the cable shield to approximately 5 mm.
To do this, fold the surplus cable shield back onto
the cable sheath.
