I've been trying to figure out why the untracked consumption on my dashboard is so high. (Today is showing nearly 25% of the total energy). I have sensors on nearly everything.
I have a solar setup with battery, the battery can (and does) charge from the grid as well as from the solar.
The energy from grid sensor I use includes the energy that goes from grid to battery as well as to the house. Should I subtract the energy that is being used to charge the battery from this sensor?

That sounds correct.

Have you counted for the energy the battery uses converting from dc to AC or the power used by the battery for monitoring and cooling

Hi yes I've been trying to work out if I could estimate the conversion losses but it's... complicated. It seems like a large amount but perhaps it's correct.

Thanks

Ive actually been chasing that as well
Still got to get another Shelly EM-50 to monitor the Cooktop (Hotplate) & Oven and more Eve Energy Plugs to monitor the other entertainment areas
Basically im trying to track wher the remaining usage is going

I think it's almost certainly losses. I can measure the actual "Home" total (it's the AC out power from my Victron multiplus), but it's not available to specify in the energy power display as far as I can see.

Once i get CT clamps on every single circuit in the switchboard then the leftover will be losses from the battery inverter most likely

I'm having the same problem: I have a general meter right down the grid power and measure clamps on all my circuit breakers but still get a large untracked amount only when battery charge/discharge is involved.
I have configured solar panels and battery in the respective section and all my clamps as child devices of the general meter. Now, since the inverter is "outside" the circuit breakers, I was wondering: do I have to, somehow, configure the battery/inverter as an individual device as child of the general meter?

Meters don't have children

The other way around. I got the clamps upstreamed to the general meter.
