jkpb1A16s10p smart bms.

[D. Abineri]

I have this smart bms attached to my Growatt inverter with a 48V LiFePo and:
1. When the system is started and I open the app, it is not reading a voltage on cell 1 ( other 15 are all read). I have check they sensor lines to the cells and all seem correct.

2. there is a flashing red led in the bms and I have no idea what that is telling me.

Any ideas on these two issues wold be welcome. Many thanks.

It sounds like the main negative isn't connected to the BMS.

I thought of that too but it is certainly connected. Thanks.

I don't know what else it would be.
You don't have anything connected in between the main negative and BMS?

I can't find that part number anywhere.

No, very strange.

I guess that is the new inverter BMS.
I don't know anything about those. I haven't paid much attention to them.
