Try `-c QPI` instead of getstatus first. This will give the protocol
version that the inverter thinks it knows (default is PI30)
Once you have the protocol try some of the individual commands next `-c`
without a command should list the available commands for the protocol you
use (`-P xxxx` to supply a protocol if it isn't PI30)

So that didn't help
Try another command
QDI or QPIGS or QPGS0 to see if any of them work
Next try different protocols especially PI16 and PI17

Looks like pi18 or a variation of it
Try commands that fail a few times with info level messages to see if there
are differences in response
And maybe both pi18 and pi17 PI command with info messages to see the
differences

Hi. I had same issue earlier this week. I often work with easun (directly), so it was easy for me to ask them the protocol specs. I can send you those specs by private message, or just wait 1 or 2 weeks, I'll adapt the lib to recognize those inverters and I'll make the pull request.

I successfully implemented all query commands. I've implemented some set commands :
I'll try to find out why some set commands are rejected. Once found, I'll implement the missing ones :
So if someone has any idea for the rejected commands, tell me ! Greg. |

theres some 'funky' logic re crc additions, in at least one place the crc is added after the EOL |

the QUERYEN type seems to put a \r before the crc no matter what. i expect this is either a bug or QUERYEN can be replaced with QUERY type and crc False |

looking at your code (havent seen the doc) vs I suspect you need an extra 0, ie edit actually nvm, cant count... |
