@batpred 

That's right the Seplos BMS manages the pack and communicates with the Inverter.

The JK active balancer I think you are referring to is completely independent and only balances the individual cells, nothing more, so that is very unlikely to be your issue.

I have 3 of these upright Seplos packs from Fogstar, which I've upgraded the firmware (and downgraded) from 1.2-1.3-1.4 and have had no issues at all, also running on a Solis S6 inverter (AC Coupled).

The JK active balancer works very well to keep the cells all aligned.

I haven't upgraded to the 1.5 firmware yet as I'm happy with where all my 3 packs are.

@batpred 

Did you build your pack, or buy it pre built?

It is a matter of luck. 2ith Fogstar "instructions", too much variation can be expected... 

But let's see what fogstar say. It may be a while... 


16kWh Seplos Fogstar battery; 8kW Solis S6-EH1P8K-L-PLUS hybrid inverter; Ohme Home Pro EV charger; 100Amp head, HA lab on mini PC
