Unsupported serial number prefix: EA

[Philhews]

I'm trying to connect to my inverter and I get the following log error

This error originated from a custom integration.

I have * out the end of my serial number but the failure comes down to the modbus code not accounting for the EA serial. It should identify as a Gen2 (because that's what I have).

I did try looking for the code ony server to locally modify but the path it lists doesn't seem to exist.

I notice this has very recently been resolved in the givenergy_modbus library, but is not yet included in a release. We'll have to wait for that to happen, then this integration can be updated.

I've also got an EA serial, it's for a "Gen 1.5" according to the installer, Gen 2 board, Gen 1 case.

Quick and dirty - edit /usr/local/lib/python3.10/site-packages/givenergy_modbus/model/inverter.py change line 26 'ED': cls.Gen2 to 'EA', restart home assistant.

I'm running home assistant core rather than OS, which might make such hacks a little easier

I've hit this issue with their GIV-HY3.6 Gen2 inverter that i had installed yesterday. S/N starts with EA.

Quick and dirty - edit /usr/local/lib/python3.10/site-packages/givenergy_modbus/model/inverter.py change line 26 'ED': cls.Gen2 to 'EA', restart home assistant.

sounds easy enough fix, but i cannot find the inverter.py file either via HAOS SSH, or a suitable container to even start to look at via portainer.

Edit: sussed it! in the portainer settings, it default hides the base OS containers. Simply goto Portainer > settings > under 'Hidden containers', remove what you require (minimum of 'homeassistant'). For HAOS, this file is in the 'homeassistant' container.

I've gone with the committed method to add, rather than replace existing.

I've now got my inverter&battery entities in HA!

Hope that helps others!

I have a very similar sounding issue

Install was just completed, so it looks like a new inverter generation. Any ideas?

This is another issue that would be fixed by #61
