Not much to report. Except that my head is spinning. Also:

My Morningstar Tristar-mppt-60-150 controllers can be fiddled into charging Lithium. I'm getting that straightened out. They don't like to lose power. So the HVD contactor goes on the PV input line. LVD is handled by the inverter.

You can fiddle the charge voltages by using the RTS and fooling it into thinking it's very cold out. That way the charger stops charging earlier. Hmmm.

My size of system, even at LVD, lots of power left. HVD is my real concern. And I'm planning on charging to 80% for the first while to observe. May just leave it there.

REC BMS is about 700 euros once all the bits and bobs are in. Pretty sweet solution tho.

And I'm leaning more and more to cell monitoring with manual or occasional balancing.

Anybody with a good idea for a cheap 72 (6p12s) cell monitor(s) that's accurate? And reports to a PC?
