558 S0 interface
In accordance with DIN EN 62053-31 this interface can be used to connect an energy
counter to the inverter for the purpose of the control self-consumption (see Section 5.5.9).
From experience, SolarMax can recommend the following electronic energy counters:
Berg MCi32WP and Berg B23 311.
The S0 interface is configured with the free MaxTalk 2 Pro service software.
Connection conditions
■
■
Energy counters are only permitted with S0 pulses for feed-in (S0 pulses for both
directions of energy flow are not permitted).
■
■
The pulse rate of the energy meter must be between 1 000 and 10 000 pulses
per kWh.
