Hi, I will write everything down and post it

So I thought I would do a quick update on my progress with getting information from my 8kw OmniVolt.

Happy to report that I have everything I need! All up and running when I workout what addresses were... What pain. But I have uploaded a Modbus reference document for all the addresses I used and what they mean, as well as their unit and scale factor... This should be helpful if anyone needs to get their inverter info into HA .

If you find any errors, let me know and I will update it! I am happy to share my config yaml if anyone needs it, as well as my dashboard yaml.
Ignore the fault... The inverter still seems to be acting weird with the SoC of the battery. I currently have it connected through 485, and WOW.

I have attached some screenshots of my dashboard showing everything working . Still lots to mess around with, but this is a good start!

Ok so I will give a bit of an update on my 8kw OmniVolt.

I have installed everything and am running 6 x 600w panels through the one MPPT. Solar is working great.

Had a few niggles with the programming and discharge of the battery. I have found that the inverter is an SRNE, specifically the ASF48100s200-H (can be seen on the comms PCB and Inverter PCB). This is the same one that is in the Sun Gold Power inverters. Seems to be a pretty good inverter from what I can find online. I have attached the manual which has ALL the information and settings 😅. This should make everyones life a bit easier. The ASF number actually corresponds with the 10kw inverters, so I would assume they just using a downrated 10kw in the 8kw Omnivolt...

If your battery is discharging to 10% like mine was, you need to update parameters 58 onwards (look in the manual). These are the SoC values, where all the earlier values correspond to voltage.

I am still having some weird things happening, like it changed the communication between the inverter and the BMS back to RS485, instead of keeping it on SLA.

The last issue I am having is that the ESS app does not show any of the LOAD states. I can get the BMS and Solar info, but nothing on the load. I have also tried using the IPower App which communicates with SRNE inverters, but I can also only see BMS and solar info. Not sure if everyone else is managing to see the load information?

Ok so looks like this is the case, the box on the outside says "None" but inside there is a dedicated instructions pamphlet showing how to connect up to 6 units in parellel.
I've had time to open the box and take a bunch of photos. I put them all in an Google Photos album you can view here: https://photos.app.goo.gl/9ztPDuSfYZrBEz7G8

I've scanned the two manuals so that it's easier to read, see attached:

@Sidewinder @Demo
I see the links are working again today, and the prices are still the same. You can use the links in my first post or just find the items on the website!
Edit: Also I have confirmation that the units are being delivered. The guy from carbonite.co.za that ordered the 3kW unit has received his unit today!
