Support for Growatt MOD series(RS485)

[Star442]

Hi,

Is there any plan of supporting growatt MOD series? It's RS485 based

Hi,If you could provide the RS485 communication specification then I can surely support it :} On 11/7/24, 21:09 Selver ***@***.***> wrote: Hi, Is there any plan of supporting growatt MOD series?

This should be it

Great thanks for the inverter protocol specification! Which BMS will you be using?
I will try to start implementing it next weekend as I'm quite busy at the moment.

[Star442]

I have not decided yet, but most likely pylontech or trying to use my nissan leaf via chademo!
Thanks no worries, is it possible to support your work somehow?

[ai-republic]

Ok, I would recommend using the Pylontech protocol as its a very widespread commonly used protocol by many BMSes and inverters.
If you like to support this project I'd be very happy! Just click on the Sponsor link on the project page! :)

Perfect thanks!

Did you have any luck with the RS484 integreation for Growatt?

[ai-republic]

I will try to finish it this weekend :)

[Star442]

@ai-republic still no luck?

[ai-republic]

Hi,
I got around to start the implementation but I was very busy last week (also my sons birthday and an upgrade of my solar system). I think I can finish it this weekend though :)

@Star442 the Pylon RS485 binding is now implemented. Please get the new Configurator , choose PYLON_RS485 in the inverter tab and do a Clean install.
Please also configure the debug log-level so that I can check if there are any prolems.
Happy testing ;)

Thanks @ai-republic ! I'm just trying it out, is there any function to use a fake battery? Just to see if the communication with the inverter is working?

[ai-republic]

No, there is only a dummy inverter, but no dummy battery. But that's a good idea - I will implement that in the next few days :)

[Star442]

@ai-republic Perfect, thanks!

[Star442]

@ai-republic did you have any time to implement the dummy battery?

[ai-republic]

I've created a plugin architecture and a plugin that has some preset (dummy) battery data but currently only for 48V systems that is currently only configured for the SMA. I'd like to create an extra tab on the Configurator app where available plugins can be configured. Need to see when I get around to implementing that. Hopefully next weekend 😃
