Support for Growatt MOD series(RS485) #39

Open Star442 opened 1 month ago

Star442 commented 1 month ago

Hi,

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

ai-republic commented 1 month ago

Hi,If you could provide the RS485 communication specification then I can surely support it :} On 11/7/24, 21:09 Selver @.***> wrote:

This should be it

ai-republic commented 1 month ago

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 commented 1 month ago

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 commented 1 month ago

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 commented 1 month ago

I will try to finish it this weekend :)

Star442 commented 1 month ago

@ai-republic still no luck?

ai-republic commented 1 month ago

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 _PYLONRS485 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 commented 2 days ago

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 commented 2 days ago

@ai-republic Perfect, thanks!
