Easun IGRID SV II 5 KW - All values are Zero

[BMBIT-oss]

Hi , I have an Easun IGRID SV II 5 KW , have made all the hardware connection and it looks ok , tested in couple of ways , but all values are Zero . Debugging is ON and I get the following :

Sent Command: QPIGS Calc: E300 Rx: E300 Recived: ^0 message recived Sent Command: QMOD Calc: E300 Rx: E300 Recived: ^0 Sent Command: QPIGS Calc: E300 Rx: E300 Recived: ^0 Sent Command: QMOD Calc: E300 Rx: E300 Recived: ^0 Sent Command: QPIGS Calc: E300 Rx: E300 Recived: ^0 Sent Command: QMOD Calc: E300 Rx: E300 Recived: ^0 Sent Command: QPIGS Calc: E300 Rx: E300 Recived: ^0 Data sent to MQTT Server Sent Command: QMOD Calc: E300 Rx: E300 Recived: ^0 Sent Command: QPIGS Calc: E300 Rx: E300 Recived: ^0 message recived Sent Command: QMOD Calc: E300 Rx: E300 Recived: ^0 Sent Command: QPIGS Calc: E300 Rx: E300 Recived: ^0 message recived Sent Command: QMOD Calc: E300 Rx: E300 Recived: ^0 Sent Command: QPIGS Calc: E300 Rx: E300 Recived: ^0 Sent Command: QMOD Calc: E300 Rx: E300 Recived: ^0

Can you point me in the wright direction please !

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 . EASUN Protocol.pdf

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 : https://github.com/BMBIT-oss/Solar2MQTT_P18

[BMBIT-oss]

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 . EASUN Protocol Real 18.pdf .

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

support added with V1.1.0
