Hi.
I got this offgrid cabin, 800w pv, 220v/3kw hybrid mppt inverter/cc , generator, 24v/6.3kw nmc battery pack from a KIA Soul.., qucc 200a smart bms. Bms low/high set to 3v/4.2v
Cell min/max is 2.5/4.3v .
Ihave set the bulk at 28.7v/4.1v and float at 28.5v/4.07v . Bulk reconnect at 28v/4v.
At "rest" in float, the battery stays around 28.35-28.4v..
This seems do work just fine.. battery cells balance nicely every time..
I'v been working with different solar setup for the cabin in many years now, always planning a upgrade of some kind.. and this one works eealy great.
But i'd like to learn more about how to optimice the settings. If i change the float settings, what is it i'm looking for? Is it better to have it closer to bulk voltage or closer to the bulk reconnect? Or all 3 of them close together? If i do some adjustments , what's the signs of doing the right ting? Bad?
Thanks,
