Hi,
i was running for a while an off-Grid Solar System (290 Watts) with a small LiFepo4 Battery and some self-build electr(on)ics in to switch automatically between Grid and Battery, i stumbled over a new Deye SUN600-G3-230 for a small price.
So i connected two of my 100 Watts Solar cells in series in order to get within the MPPT-Range (25-55 Volts) of the Grid Converter, plugged it into the Grid and by measuring, the best i got out of this was 100 Watts on full Sunshine - which i consider as rather low. Thats one of my problems.
The Second one: My three-phase Meter with a bidirectional counter (it has the correct symbol on the case, which identifies it as that), adds the generated power to the current power consumption, which is of course incorrect.
Idk if it plays a big role in this case, but i assume that the Inverter is running on a different Grid Phase than the majority of consumers in my apartment.
Why I think that? Well, the balcony outlet, to which the inverter is connected, is protected by the bedroom fuse. A few other, smaller rooms in the fuse box are summed up in a row and being protected by a single ground fault circuit interrupter.
The other rooms with the main consumers are protected by a different ground fault circuit interrupter; so I believe that two different phases are being used here.
The question I'm asking myself, however, is whether a current raise in one (in this case probably otherwise unused) phase due to the feed-in leads to a measurement error in the meter.
I am running the Meter model 2R06-DTA-ODZ1

It is configured as a two way meter (without "backstop"), but is it common that produced energy will flow into the grid, only because of a different phase, and being - added - to the power consumption??
Thank you & best regards !
