Hi, has anyone successfully hooked up a LEAF battery to a Sungrow inverter using CAN (emulating HVS)?

We're having trouble getting it to work and would appreciate a simple wiring instruction for the CAN connection between Lily and the inverter.

Thanks in advance!

I see multiple people are using the SH10RT on the Discord server.

Try checking the H / L connection between the Sungrow and the LilyGo

"Mine Sh10rt connected to H and L pins you’ve circled. I’ve tried with and without resister - everything works on short (2m distance) but it was sensitive to quality of twist cable."

Thanks for the confirmation! We got one out of two working finally, actually suspecting the Lily board my be at fault. Since we got one to work long after this was posted I suspect the issue be with the LilyGo board or the inverter. I'll investigate this further at our end. Also, thanks a lot for the confirmation!
