Hey guys,
I am running into something that looks very much like a bug, but maybe the community can help me figure it out.
My system 3 phase, multiplus II 48/5000 + cerbo gx + ct clamps on each phase. I also have an ac coupled huawei.
The connections are grid meter > ct clamps → ac coupled solar > multipluses ac in > loads on ac out, so my ct clamps are measuring net export/import
To get the remote ui and vrm to show the proper figures for grid, load, battery, solar i had to set the ac coupled pv inverter (a mqtt dbus device) to be connected virtually on ac out instead of where it is physically, on ac in.
Now for the problem, this all works perfectly except for the kWh figures in VRM, it looks to me like it is counting solar export twice or something like that, and this has a trickle effect on making all figures inaccurate.
Are there some settings to tell it that the inverter is ac coupled on ac in BUT the CT measurement is done at grid connection point? The CTs are set as external in ve configure.
thanks
/LE all figures like current and voltages are perfect, it s just the energy figures that are not ok
