Easun IGRID SV II 5 KW - All values are Zero about solar2mqtt HOT 11 CLOSED

I have changed the values , like another colleague has done it hire an now I only get : grid Voltage : 110 V ( My grid Voltage is 230 V actually ):
// PCM and PIP inverters use below
QpiMessage _qpiMessage = {97};
QpigsMessage _qpigsMessage = {110};
QmodMessage _qmodMessage = {5};
QpiwsMessage _qpiwsMessage = {36};

So I believe is something to do with the CRC , maybe ?

After some digging and a bit of wiring it looks like the protocol is a bit different for EASUN IGRID SV Series .
I have done some tapping and picked up some data from the PC to Inverter :

^P005GSX�
^P006FWS?C
^P006GMN?W
^P006GMN?W
^P006GMN?W
^P006MOD??
^P006VFW??
^P007PIRI?8
^P013ED20220707??
^P013ED20220708O�
^P013ED20220709_8
^P013ED20220710?
^P013ED20220711?�
^P013ED20220712?b

Also I have managed to find the entire protocol description Online .

sorry, i dont get a mail that a message is here....

yes looks like your inverter have different protocol, so its possibil to make my thing to work, but its hard way.
take a look at the older releases, that have snipets for this protocol

Thank you ,
It looks like this is the new protocol that Easun and equivalent will use in the future .
I have managed to modify your code and implement the P18 Protocol in to it , but is still under development and testing .

Sounds good.
Is the request command for the protocol Version the same?
I had the Idea vor Months to Automate select the protocol Version and commands, but i dont can Test anything with This.
When your Version is working, you ar willing to make a Switch for the Versions and implement it?

@BMBIT-oss can you provide your command table for the inverter?
or will you help modify the project to support mutliple commands and inverters?

I'm Not really a guru in programing in Arduino .
I have Managed to get couple of functions working and have uploaded the code on my GitHub page as per below :

This is the protocol , it's using the same CRC an so on .
The return data is a bit different but your code its able to pull all the information with an easy modification .

Nice,
When Interesst you can Join the discord Server.
I Plan to make a new one of this programm with serveral configs for Inverter and need Help to write it

This issue is stale because it has been open for 30 days with no activity.

support added with V1.1.0
