HI Nick
Thanks but I’m curious about 1 thing.
The charged voltage they list here is around 57v.
But the charge voltage specifics I just got from midnite say 56.4.
What’s up with that I don’t understand which is correct.

The FM80's LFP settings in this system are compatible with LFP but I'm looking for options other than using the Aux in the CC's wired to a NC relay and from there to the inverter on/off landings in the green terminal of the OB/FX for the LBCO and reconnect function.

I've used the Aux from a Classic for inverter LBCO and reconnect though its never been fully "tested", although I read "open" and closed" at the un-wired aux landing when I forced it with a high LBCO setting. Just thinking about the highest reliability.
