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.
the problem has been solved by placing an EM24
There are options in the ESS settings
Also under energy meters there are options as to how they are connected, however you must also connect a rs485 to usb cable to the GX device to see the meter.
so check in those settings as well
and see if that helps
with AC loads on L1, no consumption is also shown when the solar panels are working. while there is actually consumption there. when you switch off the solar panels, there is consumption on L1
