question

As a suggestion I would consider putting the panels into series thus the PV voltage will raise to 88 volts, (much better charge early mornings, late evenings and heavy cloudy days etc) Do not go over the max voltage of 100v on the MPPT unit.

Re BMV Alarms for the whole battery, I would set the BMV to have low voltage pre waring of 25V and Hi Voltage Pre warning of 29.5V

if you are going to use the Time To Go function on the BMV then make sure you set the relay control setting for SOC to OFF or change it to 20% (current default is 50% ) as the TTG is based on this setting and bank capacity. otherwise TTG will always be reading LOW

sometimes I set my battery capacity to the usable level your capacity is about 60A/H so set this to say 50 A/H so that when the SOC reaches Zero you still have 10% Buffer left. if you do this then the Relay setting for SOC also change from 50% to 0 (or OFF)

you should have a cell level BMS for the batteries as well, This is highly recommended (plus as time goes on you will learn why they are so important and then as you expand you wont have expensive battery issues)

if the batteries are lithium phosphate then HV cutoff 30 volts

LV Cutoff 20 to 22

also if any one cell voltage reduces below 2.5v then cut off or above 3.8 to 4 volts also to cut off

the cell level control is quite important in my opinion.
