Here's a quicky... if you have any question - please feel free.
Here are my "Basic" settings....
1) Disable Equalize by setting hi/un-attainable voltage + time of 00:00 + 0 Interval + 0 Retry . This doesn't apply to Lithium and you don't want it to run.
2) Absorb/Float are 'the same thing' - e.g. the max charge voltage. Float cannot be any higher than Absorb - 0.1v. So I just set Absorb to the voltage + 0.1v that I want and Float the voltage I want. In my case Absorb = 56.6v and Float = 56.5v. This translates to a max charge of 56v as reported by Batrium.
There's a bit of a difference between Absorb/Float settings and *actual* max charge as reported by Batrium. You can make adjustments in the "Tech" menu (below) but I just would up experimenting a bit made it match what I wanted as reported by Batrium. Easy to change/tweak and you'll find something that works for you.

Here are my "Advanced" settings...
1) Aux 1: is used to turn the AIMS inverter on/off. Right now its on at 51.5v and off at 48v. Typically I run at 49.5v off. The idea is to let the battery charge up a littler higher than low-cut-off so when it turns on it won't immediately hit low/cutt-off.
2) Output Amps are explicitly set to 80a because that's the breaker size I have on the wiring going to the battery. I had a case where my panels actually produced 85a and tripped the breaker and I was running around trying to figure out what happened!!

On the "Tech Menu"....
1) Ending Amps, Rebulk... I just ignore these. The Ending Amps can be used (somehow) with Wizbang Jr (The shunt) to reset aH(s) for SoC stuff. See the reset at Net Ah at 100% SoC setting below.
2) Offsets - you an adjust this to bring the Midnite in alignment with Batrium is you want. I fooled with it - e.g. the "-0.5" voltage setting but just moved on to the comment up above.
3) I REALLY LIKE the Arc Fault feature and enabled it. This will detect 'bad connections' in your solar panel hookup if they are arcing due to intermittent connections. I had to decrease sensitivity by 1 number as it went off a couple of times

**Don't know how you feel about ModBus code but I have full working PHP code to read all these settings in batch for my internal DB and tracking. I didn't bother to do the 'writes' because its easy to set thru the interface. Happy to share the PHP if you want it.
This is how I get this 'low-tech' web page that refreshes every 5 secs... so I monitor the Midnites. I also parse the Batrium log every 5 mins and combine the 2 sets of data to produce this dashboard:
