– You will find a list of supported energy meters with D0interface in the planning
guidelines "SMASmartHome" at www.SMA-Solar.com.
– Recommended resolution: at least 10Wh
– Information: for the function Limiting of active power feed-in, the energy meters with
D0interface must have a resolution of at least 1Wh.
• Energy meter with S0interface in accordance with DINEN62053-31, classA:
– 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.
– Bidirectional meters with an S0interface must be equipped with twoS0interfaces.
– Recommended pulse length: at least 20ms
– Recommended pulse rate: 1000 pulses per kWh
– Information: for the function Limiting of the active power feed-in, energy meters with
an S0interface must have the following minimum pulse rates:
– At a maximum allowed grid feed-in of more than 1500W: at least 250 pulses per
kWh
– At a maximum allowed grid feed-in of less than 1500W: at least 500 pulses per
kWh
Router
The use of a router that supports DHCP is recommended.
All network components used must support the IGMP protocol, minimum version3 (IGMPv3).
Other Devices
