Please, by connecting without load, do you mean just disconnecting from the inverter with the BMS switched on, or simply connecting and disconnecting from the inverter with the BMS switched off? Thank you.

I would also like to thank you for your great work. I really ask for advice is there already a way to monitor two batteries on one panel? The Deye (sunsynk) 30Kw HV inverter allows two batteries each with its own BMS1 and BMS 2 communication, each with its own voltage and its own SOC. I can add up to four MPPTs to a panel today, I would need the same for the batteries. Is it possible to add an option for multiple batteries in the settings? Alternatively how to write in the code I am a beginner, but I have been using your Power Flow Card for over 1/2 year to complete satisfaction until now I added a second battery. Thank you
