I have a 3 phase network, 400V +N. 1 multII on L1, an sma inverter with a single-phase energy meter on L1 and a fronius inverter on L2 that communicates via the internet. the problem is that the solar energy from the sma on L1 is counted as consumption in the AC Loads. the values that the Cerbo GX gives are not correct, a lot is injected and taken from the net, while the digital meter of society announces something completely different.
