Hi Bill
What was the charge voltage before?

Midnite just changed their absorb voltage to 56.4V. For what its
worth, I treat the batteries from manufacturers exactly the way
they say, I don't want to do anything that may jeopardize the
warranty. Also with LFP batteries, its not just a pile of cells,
no doubt each manufacturer has their own tweaks to their
proprietary BMS, some have heat, some don't, all absorb set points
are not the same, etc.

Hi Jay
The settings for the MNS Batteries are on a sticker on each
battery.
BMS- LVCO 44.8 HVCO 58V (The HVCO is not on the sticker)
LVCO (inverter) 46.0
Float 54V
Bulk 56.1V
The rest of the you can set to what you want, the battery
does not care.
All Prismatic cells operate mostly the same, and the MNS
Batteries use A+ Automotive cells MFG by EVE.
Thanks

Hi
Bill
I tried and failed to find any setting information on that
battery besides charge and float.
Kinda need to know things like LVD, recommended LBCO, etc.
But if it’s similar to other prismatic cells you should be
able to set the OB inverter to a LBCO that works without
having to go through a aux relay.

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.

thinking about the highest reliability.
