SRNE inverter support #32

Open Dimu1234 opened 2 weeks ago

Dimu1234 commented 2 weeks ago

Hi & thank you for the project. Does this support SRNE inverters & if not, do you have any plans to improve this to add SRNE inverter support?

ai-republic commented 2 weeks ago

Hi, thank you for liking this project :) As far as I researched quickly, your SRNE inverter should support the PYLON CAN protocol if you enabled the CAN support in the inverter (32 - CAN) and CAN mode UZE in option 33.

Which battery system or BMS(s) do you have?

Dimu1234 commented 2 weeks ago

Thank you for the quick reply. I'm having JK-BMS with assembled LiFePO4 battery pack. (16 cells of 160Ah, 48 V)

Ah ok, so you can test if you get reading using the JK BMS binding (choose _JKCAN in the Configurator app). For the test please enable debug log-level and as inverter choose NONE for now. Which CAN hat do you have for your Raspberry PI? If none yet, I would suggest the Waveshare 2CH CAN hat as you'll be needing 2 can ports (one from BMS to RPI and one from RPI to inverter).

NOTE: We have discovert that the Waveshare 2CH CAN hat does not (currently) work with a RPI 5. If you want to buy a PI for this project I would suggest to go with the RPI 4B for now.
