Inverter self consumption from existing entities

[Louix73]

Thanks for the integration, it works relatively ok. Like a few people some unstability on modbus but I can live with it.

My question is, like the instant power solar generation, is it possible to create a sensor that will extract the self consumption of the invertor as it is working?
Basically it is quite obvious that the inverter is consuming about 600-700W a full load for me, so I was wondering if this is possible.

I come back to this with more clues
It annoys me as it represents a relatively significant share of not explainable untracked consumption.


The interesting part is that when the production equals the consumption, it seem I don't have losses.
If the suspition is correct, that gives me about 27% of loss on the battery and 3.5% on solar.

I found the following curve of efficiency for the inverter (SE10K-RWB48)

Which says that the lower the load the worst the efficiency and therefore correlates with the above. Solar isn't far off but for the battery that's a sharp drop...

Maybe how I have the energy configuration is wrong but I can't find where
