Integrating SRNE MPPT Inverter with HA

casasicilia · February 2, 2023, 7:51pm

solved

Baud Rate 9600 and everything go well

Hi Mattie
I have a question.
How did you setup energy dashboard? I mean battery storage. SRNE inverter doesn’t give data in kWh. Mathematic is simple but I don’t know how to setup it in HA:(

Mattie · February 4, 2023, 11:06am

Hi! You were right about the colors, my bad. Actually I think I have them the other way around, I dont really think it matters? I tried a lot in the beginning when I didnt get any data so I guess I just left them as that when it finally worked.

As for the energy dashboard I got influx and grafana if you wanna go and do those handsome graphs.

And in hassio I have been testing out different calculations for my template sensors, I’m sticking with these at the moment, the battery charge/discharge actually seems pretty acurate even tho I use a non changing 24.8 for voltage, I have been thinking about making an input_number that gets populated by the current voltage every hour to make these calculations instead in the future:

I use the battery charge discharge in Ah from modbus

My latest version of the solar-dashboard looks like this:

Do you get any unavailable states when the sun is out from your modbus waveshare gateway? My current problem is that when the sun is out I get “unavailable” state very often, this only happens when the sun is out, almost as if the inverter prioritizes the internal mppt calculation and not the modbus protocol when it has to “work more”

casasicilia · February 6, 2023, 1:07pm

Wow
Thanks for you Mattie I learned what is template sensor. Game changer I have to say.
I have no problem with states. After 3 days its looks solid.
Did you connected GND wire to waveshare gateway because you didn’t mention about it. Or try my baud rate settings.
Ps. Do you have SRNE address book, I want to look inside

Mattie · February 6, 2023, 3:10pm

Yes templatesensors solve many issues!

Actually I haven’t connected the GND at this point, maybe I’ll give it a try. Of course I have plenty of modbus requests also, at least 20 different sensors polling the gateway even though some are grouped into one. It is possible that I’m on thr limit of what the inverter interface can deliver also.

I’ve pasted the modbus address index in this post. Enjoy

Never forget the GND!

Everything seems fine now! Thanks for reminding me! Also I had the colors right, I just fat fingered in my initial post here

casasicilia · February 8, 2023, 6:56pm

ha! good to hear that:)

In my case I finishing polishing my dashboard. Only problem I have is 12S battery and can’t setup it in inverter

Did you try writing registers? in my case I want to control charging/discharging via HA. I have connected BMS to HA and by this data I want to control stop/start charging

Mattie · February 8, 2023, 7:10pm

Nice I control my SRNE with HA writing registers to control charging mode and source mode. I have an integration polling the electricity price forecast that sets an automation to start charging batteries on the lowest cost hour. Works great, I also have an automation controlling the load so that the battery never goes beyond 24.4V on my 6p2s batterybank. When the voltage gets close the automation sets charge to “PV only” and Source to “mains”. I posted about writing registers a few posts up here, just use script

Mattie · February 10, 2023, 11:23pm

What SRNE model do you use exactly? I see that you got almost 3kWh from solar. And I already need to upgrade…

Also where did you buy it? Anything you could recommend?

casasicilia · February 11, 2023, 8:43am

Hi Mattie
My model is 5k older SRNE

I’m not super turbo extra happy about it because of minimum battery voltage which I cannot setup property. They got software limitation to 40V and I cant go lower with it
They selling it on AliExpress and I sow that they got new model. I’m living in Sicilly and from 10 panels and this inverter I got more power that I need during the day and generally I’m very happy about this setup

Mattie · February 11, 2023, 10:58am

Actually I’m looking at this model now, did you order from Ali? Was it all good?

casasicilia · February 11, 2023, 4:27pm

no no, I bring it from Poland, I’m polish guy who moved to Sicily. But a lot of my friends ordered from Ali. You have to wait a little but its working well

Mattie · February 11, 2023, 9:09pm

Actually I’m also from Poland but live in Sweden. where did you get it from?? You could dm me!

Edit, saw your dm now

colseven · April 2, 2023, 9:16am

Hello,
Can I also read this out with ESPHOME (ESP32)? I have an RS232 at the inverter and could read that via Modbus, right?

Mattie · April 3, 2023, 8:12pm

As long as you communicate with the same protocol you should be able to use esphome to do it with the code above. I’ve seen a few videos on yt where ppl do it. It seems like a more troublesome way though. The waveshare unit costs about 25$ and it’s pretty much plug and play I already have two of them to a srne and a epever tracer (differens modbus addresses ofc)
Works pretty good

Patriarken · July 1, 2023, 10:19pm

Mattie and others thanks for the great information in this thread. I own the 3000w SRNE hybrid inverter, and the waveshare gateway linked in the initial post by Mattie(My inverter is the 110v version since I live in Japan(I am Danish though). It was dead easy to set up thanks to this thread. I know how to make scripts in HA however I lack the reference to the registers. What I am trying to accomplish is something like what Mattie is doing ie change the working mode between CSO/OSO etc in setting “6” in the inverter display. I saw that you shared a pdf with those Mattie but the Link has expired could you repost it or can I dm you with my e-mail and have you mail it to me? I could ask SRNE support and I have tried but they dont seam to respond Thanks in advance Best regards Anders

Mattie · July 1, 2023, 11:12pm

I envy you, I LOVE Japan and would like to travel there sometime

Send me your email address in dm here and I’ll send you the file when I wake up tomorrow, it’s 01.00 here in Sweden. Or if you want I can give you my whole config. I have two different models now and it works like a charm on both of them

Patriarken · July 2, 2023, 7:08am

Thanks a lot for the kind words and your quick reply. I can’t make dm’s for some reason however, so I will type my e-mail it is: xxxxxxxxxxx. I would love to have a look at you config files if possible and not to much trouble. I am very impressed with your setup. Thanks again I really appreciate it. Tack så mycket!

Mattie · July 2, 2023, 10:18am

Figured I might as well paste my raw updated code here. Excuse the mess in the code, much trial and error so I’ve commented some parts away that I dont use but may wanna get back to. Take what you need

I have a Waveshare RS485 to ETH on my PowMR inverter. The communication is established, data is being sent and also received, but I’m probably querying the wrong register via modbus. Can someone help me here?

Thank you very much.
