[RE-wrenches] Midnite Powerflo16 to old OB inverters

[Jeremy Rodriguez]

Today I installed 3 of the MN
POWERFLO 5 batteries with an OBVFX3648
Per the battery label I was able to set the inverter LBCO to 46 vdc.
I see that the battery BMS range
Is 44.8-58 vdc
We should be good to go.

Here is the voltage vs SOC approximation chart from Midnite. Was helpful for me on my first couple installs as I awaited some additional details about their batteries.

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

Logan

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.

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.
