You guys are a-freaking-mazing. I salute you for your time, efforts and ingeniuty! I'm a total HA noob, and have not yet taught myself any python, but will doubtlessly return here to integrate my inverters better. I now have: Goodwe ES5048 as main, with ~6 kW PV (One string Longi, one CS) and ~30 kWh BYD on one of the non-esential loads from the ES: an Ecco 5.5 with 5.2 kWh Ecco battery and ~2.2 kW CS PV on another of the non-essential loads from the ES: a Rizzen 5 kW with 5 kWh Rizzen battery (I'll need for a ship to come in to add PV here, but that would probably allow me to address ~30 of the 40% of my electricity not covered by the ES) I have installed an integration for the Goodwe on my HA, and it works OK (via network). I'd like to do the same for the Rizzen and Ecco. The Rizzen looks suspiciosly similar to the Ecco, although the settings are slightly different. I think the Ecco is actually the more configurable of the two. I was given the Ecco system, and I've not yet managed a way to get the wi-fi dongle/logger re-assigned to my own email address to be able to access anything via the ESS app, but the Rizzen one went quite smoothly. Do you guys know if I would be able to access the smaller/cheaper inverters via their wi-fi connections, or would I need to lay cables? Sorry if this is a very un-educated question. If you would rather point me at a place where I can properly educate myself first I'd also much appreciate it! As to the dream I aspire to: In the end it would be great to colate the inverters' data in HA, and build some logic in there that can swith things on and off to optimise energy harvested. I also have an Emporia on most of the main loads - so that information I would like to also use. The three solar geysers already have 'Tuya boards'. Feeding back into the grid is definitely not woth it for me - I'd rather use excess energy to swith on borehole pumps, eventually automating the valves that use my booster pump to supply water to te house and use less municipal water when I have excess electricity, fill my pool, switch on aircons, extend or reduce pool pump running time (solar heating panels being the main reason to deviate from minimum hours - there is a 50mm diaphram valve ready to do duty on the heating system itself when I eventally get around to properly utilising HA) etc. Cheers!

Thanks for the advice! I have aslightly different challenge. I 'inherited' an Ecco inverter and battery, but the dongle is still linked to the previous owner's account. How does one undo that connection, please?

@TRINITRON At the right price, I am.

I am not an expert, but I have found this installation example elsewhere online. The backup loads (and PV and batteries) are separate, though - so not actually parallel, I suppose. Thinking about it; one could probably use any other inverter if multiple monitoring sites etc are not of concern? Connection-2-hybrid-inverters.pdf

Item Wanted: GW5048D-ES or similar Packaging Essential: no Desired Age: post 2020 Location: not important Willing to accept a shipped item: yes Ballpark/Budget Amount: R10,000 I have a 2020 GW5048D-ES, I want to expand my system by adding a compatible Goodwe inverter in parallel to add additional PV strings. I'm located in Pretoria, and I'm willing to accept shipped items if I cannot collect them in person.
