Hi All …
PROBLEM SOLVED !! The Solis S6 Comms works fine, it was caused by a physical problem in the Comms socket to plug mating (the B- line was not connected through!!). It’s taken me days to get to the bottom of a stupid fault!!!
Full story and some pics explained in this link.
Many thanks to everyone for their input and help.

Hi
New to the forum.
I’ve just got the Solis Rai and using this forum, I was able to get Raw Modbus working using the Datalogger. No Solarman v5 protocol involved at all which I’m not sure is a good thing or not 
My issue with the modbus registers in circulation is, I’m unable to locate the correct register for the PV CT meter. Ive checked all the FC4 registers from 33000 to 33300.
Does anyone have any idea which register is used to get the PV reading from the PV CT? Or does anyone have an updated modbus doc for Solis? I’ve raised a ticket with Solis but they haven’t even picked it up yet
Edit, seems I put this in the wrong thread: the related thread is Solis Inverter Modbus integration
Hi Robert,
I am close to going crazy on trying to get my Solis RHI-3P10k-HVES-5G to answer via Mobus. No luck at all! Reading out the Acrel Meter was quick and workig right away. But my Solis: no way!
After I had used a commercial modbus to lan adapter, I have now tryed to go with an D1 Mini with ESPhome. Again: Acrel - no problem. Solis Inverter - nothing!
I am using the Modbus Register Document von Ginlong ( RS485_MODBUS Communication Protocol
Translated on 2021.5.6).
You wrote that you do have a working configuration. Would you be able to share that?
There must be something I am missing here…
Many thanks!
I have started to add in Solis support in my custom_component Integration. Universal Solar Inverter over Modbus RS485 / TCP custom_component (Formally SolaX No Pocket WiFi) - #794 by wills106 It’s not been tested yet and only contains Serial numbers for Single phase such as RHI-6K-48ES-5G
You’ll know if it’s the correct communication protocol if you get an error in your log _LOGGER.error(f"unrecognized {hub.name} inverter type - serial number : {seriesnumber}")
I can then add the first 4 or 6 digit’s of the serial number so it can auto detect.
For example the Solis RHI-6K-48ES-5G. starts of 603105. 3105 being the model number and the 60 is the kW rating of the Inverter.
If you would like to beta test Solis support in the Integration let me know.
HI Will,
sure, why not giving it a try.
I own two Solis RHI-3P10K-HVES-5G inverters.
I have been trying to use a D1 with ESPHome to establish communication with my Solis Inverter.
But I also own a Waveshare RS232 / RS485 to ETC converter (Type: H7-4). Its not listed on your wiki Page and also offers a lot less options to work with. So maybe not the right device for the job.
One of the SN starts with: 110CA22
Solis cloud does have a rest API but it is not enabled by default. It took two support requests and four weeks waiting but support now tell me it has been enabled on my account.
While waiting I did a proof of concept that showed it was possible to screen scrape parts of the web GUI using Selenium
Support tickets can be raised at Submit a ticket : Service Centre . The API is described at 锦浪监控

Hi!
I’ve managed to get the Solarman integration to connect to my Solis inverter via the WiFi stick…it was a bit of a #&# to get it set up so the stick would accept connections but now it seems to be working fine. However, I’m hitting the same problem of not knowing the registers to hit for the data I want to extract. I have managed to get quite a few of them and have created my own parameters.yaml file (based on the Solis Hybrid config). I can get the DC-data, live power, daily/monthly/total generation, frequency, temperature etc…but there is more data there that I’m keen to pull…
Did anyone find a reliable source? The supposed official guide (Modbus Communication for Solis Inverters : Ginlong Solis) doesn’t have the right addresses but does show what is available, the reference guide provided at Ginlong Solis (PV) data logging. MODBUS registers map. is also a bust. However I did glean some useful registers at Reading Ginlong Solis inverter over serial and importing in Home Assistant over MQTT :: Sequr and at Solar Upgrade Solis 1.5kW inverter and Raspberry Pi RS485 Logging as their code examples contained addresses which brought back the data I needed!
But I’m rather hoping that someone can point me to a more comprehensive guide of share the registers that they’ve uncovered. I can’t share what I have now as I’ve made some more changes and it is dark here so the inverters are offline and I can’t test anymore…
Hi all, I had the same problem with my S3 inverter, but I didn’t want to allow uploads to their servers. So I ended up writing a small python script here to grab basic information from the web interface of the stick.
It publishes the data to MQTT and sets up the entities automatically on home-assistant. There are some Dockerfiles to containerize it (as I am doing).
There isn’t much data available on my web interface but for me the power, daily and total energy statistics are enough to set the Energy Dashboard on home-assistant.
Did you ever find the register number for the CT meter?
Hi xion, my solution is currently working in both, and has been stable for a few months now. Please check out the post above and the github with the esphome config & schematic for how to do this!

Hi Will,
I have an Solis invertor Model: RAI-3K-48ES-5G
Serial Number: 0602622xxxxxx63 (15 digits) starting with 0. This is what’s listed in the Solis Cloud.
I am using the Lan stick (not WIFI) and I can see that the integration is getting the serial number but not recognising it (not surprising).
The message in the log is
“unrecognized Solis inverter type - serial number : 0602622xxxxxx6” (only 14 digits)
Is it possible to support this?
Thanks
Andy
Looks good. Adds to home assistant fine now and values look ok on initial glance.
I’ll play more tomorrow and update if any issues.
Many thanks
I’ve stumbled on this thread after searching through integrations etc. I don’t know how aware everyone is with Solis, but they’ve recently opened up their API to home users. You need to request access to the API through their solis-service platform, but to be fair, the agents that assist are pretty quick. I think I had my API access approved within about 24hours.
I haven’t integrated yet, and I have little free time to handle it on my own. But if someone was to get started and map out the feature’s I’d be more than happy to help when I get a bit of free time. The documentation provided is extensive and it looks like there are just reams of endpoints and data points we have access to such as from the inverter itself down the data that is logged on the datalogger.
Hello Sean,
I plan to integrate my Solis inverter into HomeAssistant as well. There seem to be quite some ways to do it.
1: Without any data logger directly via the RS482 Port. The protocol seems to be open (I found a pdf about that)
2: With data logger installed - just grab the data from the TX line
3: Grab the data from the Website using a python script
4: Use the API
Well, option 1 is a no-go for me, because I want to use SolisCloud.
Option 2 sounds interesting and I’ll have a look into that. I found a lot of rudimentary documentations on that topic, so I guess I’m gonna start with a RS485 to TTL converter, an Arduino and a serial Interface …
Option 3 is also a no-go: I don’t want update delays of 5+ mins…
So Option 4 sounds really interesting. But like option 2, I can’t find any information about the refresh rate. If the API is as “fast” as SolisCloud, then it’s pretty much useless …
I ordered the API access aswell, but the Ticket System seems to have lost a lot of performance. Ticket is still pending and not assigned … since 2 days now. However, I want to give this Home Assistant with a Solis Hybrid inverter – A taste of Blue Feathers sort of documentation a go once I got the API access.
Has anyone set up the API access and can say something about the refresh rate? Same goes for the RS485 Link: How often does the data logger reads data from the inverter?
Just a quick follow-up
I got the API running - it’s quite straight forward if you use the tutorial of the post above.
Now I can answer the question 4 
The update interval of the API is: 5 Minutes! I really did hope it would be a bit faster, but hey - it’s a quick way to read the Solis without any additional hardware and set-up/coding. You can actually spend hours to set up the visualization because there is a shitload of information …
Yea - it’s in german and it’s not nice, but I’m on a learning curve. Started using Home Assistant just 5 days ago …
It’s kinda funny, because once I got the setup it began snowing and now there is a fine layer of snow on my solar panels. My peak output is 68W 
But I have faith in global warming …
What kind of adapter do i need to connect a RS485 adapter to the COM port on my Solis - S6-GR1P3.6K-M
I used a standard 7 pin DIN socket - any of the sockets here Amazon.com : 7 pin din connector
Then removed the housing - and the remaining socket is a perfect fit
How did you hook up your Acrel meter?
Is it connected to the Solis inverter or is it a standalone?
Can you explain how did you get the Acrel meter to work with HA?
Also, what readings are you pulling off the Acrel meter?
