HMS-800W-2T AC Daily power missing #34

Open mrk-gda opened 1 day ago

Hy There is no info of daily energy AC. There is no info total Enrgy AC as well. Is possible to fix it. Daily energy AC is most important. Below output from inverter. dtu_daily_energy is not AC but DC. Is possible correct this ?

AC Daily energy should be found in the DTU device, not the inverter.

There is no total AC energy provided, unfortunately. You'll have to calculate that yourself via a helper.

This code talks to DTU integrated in HMS-800W-2t inverter. There is data dtu_daily_energy field (last line) but data in this field is not AC energy but sum of energy from PV panels (DC energy).

I'm not entirely sure if I got it right, I'll try to give an answer anyways.

From my experience, thedtu_daily_energy is AC, since it sometimes differs from the sum of the energy_daily, especially if two modules are connected. It is usually slighty lower than the energy_daily field due to e.g. conversion loss.
