[RE-wrenches] Midnite Powerflo16 DOD vs Cycle life

Tue Feb 4 08:07:35 PST 2025

Hi Jeremy,

I am under the impression that leaving at least 10% of capacity will extend total cycle life. 
The chart states 50.4 volts is a 10% SOC. 
 Then there is the LBCO delay time that may allow battery shutdown before the inverter does.

Of course the  OB FX LBCO upper limit is at 48 volts thus the recent search and discussion for a seamless external inverter shutdown to get users attention if an AGS is not in the mix.

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.
