Personally I use pzem power monitors with esphome to measure usage from the grid and almost every circuit in the house aswell as many appliances, it likey gives you much better data and better polling rates than any inverter could, such as power factors and frequency aswell as all the basic stuff V,A,W,Wh I think each one costs less than $10 including the esp.

This is totally new to me, so you put a pzem sensor on every appliance or circuit at a cost of about $15 each and they communicate to ESPhome?
Yes kinda esphome is more the information broker and coding companion similar to Arduino ide this allows you to program the plc/sbc which then talks to home assistant and stores the data.
So this may be of interest from what I read the sol-ark registers are similar to the Deye ones with some minor changes it should work using an esphome device though if you wanted really reliable info it best to connect to the esp via lan rather than WiFi.

Considering the work they put into the settings cards for home assistant I would hope they work, seems like they have all the registers figured out seems pretty nice tbh I'm still undecided on going Deye or Solis after looking at this I'll need to take a look how far they've got with esphome and solis or this might heavily sway my decision

I don't have Solis and don't know anything about them, but I have Deye and I wouldn't go with Deye again. The hardware itself may be ok, but the support is non-existent and if you ever have a problem you only have this forum for support. With Deye, assume you have zero warranty as well. Basically assume the company Deye doesn't exist after the purchase.
Noted !! The Solis is pretty well worked out also, though unless I want to hack the WiFi dongle that comes with it I'll need to find some proprietary connector on ali if I want to build my own esp comms device.

No, I started using Solar Assistant, and it works really well, so I haven't bothered to bypass it yet. The other investigation I haven't done is just to snoop on the serial comms.
