Thanks, that’s interesting. @arzaman and @Der_Hannes can you share your procedure? I could then do a how to in github.

Thank you for taking the time to document your procedure.

I have documented the process in the below link: https://diysolarforum.com/threads/how-to-flash-atom-s3-with-esphome-ha.83457/ Hope it...

OK. Sorry but I don't have Atom S3 board.

These are functions that help prevent OVP from triggering with an unbalanced battery or with runner cells. If your battery is well...

Yes 0.003V is very low, default is 0.01V. I personally use 0.005V.

In addition, with a charging voltage of 54.2V, the cutoff amps is close to 0A, see the links cited above.

Because one of the end-of-charge conditions is that the equalization of your cells is completed, which is not the case.

With switch balancing enabled, charging only ends when your cells are equalized. Delta cell V. must be smaller than Balance Trigger V.

Wait a moment. The EOC then Float status arrives when the equalization is completed.

If you use TimeOfUse you must at least have a time slot where you request a 100% charge otherwise you will never charge to 100%. You...

In the case of using an ESP32 JK-BMS-CAN, the ESP32 and our software is the only component that communicates with the inverter. The 100%...

Because the 100% BMS is not always true and some brand of inverter stops charging at 100%. If you remain stuck at 99%, your battery has...

54.2V is a very low charging voltage for LFP. Do you use TimeOfUse with Deye? Can you send a screenshot of your BMS settings?

Hi, 99% means charging is not complete. The canbus sends 100% only when the charging phase is completed when the status is EOC or Float.

@chaosnature The multi-bms code (several BMS connected on the same ESP32 as with PVbrain2) will soon be ready to test. I have been very...
