Hi I'm having an issue to read values from an SG40CX. I don't know if I should paste here but just be sure, this is my output on pastebin : https://pastebin.com/SqD1Ep3p

It seems to be reading some values but the output is always 0 or nothing at all. Included here the output of the webserver: https://pastebin.com/n8LkGWP2

Greetings and I hope we can work this out together!

bohdan-s commented 2 years ago

Looks like you have the “encrypted” modbus. Change the setting: connection: sungrow

yoursnack commented 2 years ago

Hi, thanks for your quick reply. However it gives me practically the same output.

https://pastebin.com/mKh04WpM

Even if I try port 8082, it can connect, send but gets no reply

bohdan-s commented 2 years ago

Remove the port option. connection: http ;) third time is a charm right?

yoursnack commented 2 years ago

Nope, that also did not work. https://pastebin.com/Cc8U90yJ I did a port scan on it and I guess port 80 is not open at all. Is there anything I can do to help find out what it is so others will not be stuck in the future?

EDIT: What about that https thing?

bohdan-s commented 2 years ago

What dongle/Ethernet adapter are you using? Does the data publish to iSolarCloud at the moment?

yoursnack commented 2 years ago

WiNet-S from Sungrow, it is publishing data to iSolarCloud. Using it over Wifi by the way

bjeanes commented 2 years ago

I am in a similar position. SH5.0RS using a WiNet-S (version M_WiNet-S_V01_V01_A) connected both on WLAN and LAN, trying to connect over LAN connection. connection: http works, but neither sungrow nor modbus work.

It eventually prints out 13 registers, but with predominantly zeroed values:

@bjeanes the WiNet-S only supports HTTP method. Modbus gives errors or bad data.

bohdan-s commented 2 years ago

@yoursnack sorry for the delay, you can only have 1 session open via HTTP do the dongle (well you can have more but its unstable). Try restarting the dongle and connecting via HTTP port 80 and it should work.

bjeanes commented 2 years ago

@bjeanes the WiNet-S only supports HTTP method. Modbus gives errors or bad data.

I'm gathering this. Is this likely to be permanent? If so, are you aware of an alternate dongle I can replace to use Modbus directly? I bought this inverter with the intent to send Modbus commands, not just reading registers 😬

bohdan-s commented 2 years ago

Thats up to Sungrow to fix :( Some German users are saying their firmware (v10) is working on the discord.

We "can" write registers via the HTTP method, I just haven't implemented it.

What registers are you interesting in writing to?

bjeanes commented 2 years ago

I'll email them to add another voice to hassle them about this.

Interesting... When I visit the IP in browser I am asked for an installer login. Perhaps with those credentials Modbus access can be enabled and their installers did so? (wishful thinking on my part, probably).

We "can" write registers via the HTTP method, I just haven't implemented it.

Oh! Interesting. That might work then.

I'll have to review my notes from a few months ago when researching this. It's been evicted from my brain while waiting for the install to take place. But the use-case is describable: I want to be able to force charge and discharge programmatically. I'm on a wholesale energy retailer and have a pretty sizeable PV array and battery. While arbitrage is not really long-term profitable, during wholesale price spikes as have been happening a lot in my region (and probably everywhere), selling a % of my stored energy is something I had hoped to make work.

Edit: So, IIRC my theory of how to accomplish this based on my notes was to use hold registers 13050 (EMS mode), 13051 (charge/discharge/stop command), 13052 (charge/discharge power) and/or 13058 (max state of charge) and 13059 (min state of charge). These are the registers applicable to hybrid inverter as per 1608064349708-communication-protocol-of-residential-hybrid-inverterv1.0.20-1-1.pdf but may obviously differ across some products.

alangibson-philips commented 2 years ago

Just adding a datapoint. I have a Sungrow SH8.0RT with WiNet-S dongle (firmware version M_WiNet-S_V01_V01_A). Neither modbus nor sungrow connection settings work. However http works perfectly. It even worked when I was logged in to the web app. I was just summarily logged out when connecting with SunGather.

Errors are just a whole lot of

@alangibson-philips update the firmware on the WiNet-S and you will get (admittedly somewhat buggy) Modbus connection working.

The sungrow type is misleading (perhaps could be renamed) and is for the encrypted modbus which older SG inverters (or dongles?) used. The new SH##.0RS/T don't use it.
