8 large Crown battery 6v 235 amp for 5hr for 48v system

I am a novice and I am new to your group. I have had very good luck with a solar system in a hunting cabin up North 150 miles in the Bush. I decided to try again at home mostly for emergencies. I combined a small generac, company generac installed and my 6000 watt Sigineer split phase inverter/charger 240v with triple output for 20 seconds. 100% Ames but cheaper cost. I believe this is a good match for a small sub panel /generac generator.
My question is how long should my large Crown batteries, purchased new, run my inverter. 8-235amp for 5 hr 6 volt= 48 volt . My inverter shows 3% and most of the time 5% use. I do not use powersaver it kills my alarm, camera and wifi. On low or no use. without powersaver it draws 1.7 amps. Too many times I go to bed and sleep and the Generac generator kicks on at 4AM. Yes the inverter is set to "save batteries " by auto shut down at 44 volts. Full bat charge at 5PM. and shut off 9 hr later. I have a 2kw pv with plenty of power in the day time but die 10 hrs later with what I believe is near idle power use. Only 240v is my well pump for showers. Sump pump almost never is on. The blower motor is on with the air conditioning but not the compressor. Compressor is street power. How long should I be able to run on my 8 large Crown batteries????? Thanks I am a green horn that got lucky in the past with a cabin and very little cost. We use it for a few days to a week in the summer frequently and in the fall for deer hunting. NO BEAR HUNTING but we have a lot bruens around.

Am I wrong in believing 5% use on the front of the inverter display is very low amp draw that should have the bat last for many days without sun? Inverter uses at idle is 1.7 amp. 5% of 6000watt = 300watt/ 240 = 1.25 amp so it default min is 1.7 amp draw.
What is the math on my bat bank for it to drop from full approx. 60v to 44v and inverter shuts off. How many amps used from full to shutdown. I know my week link is the bat but will wait a few years for technology to go up and price to go down.
I like my .2 of a second response time for inverter to kick in when street power shuts down. I like my generator auto backing up my inverter but it takes about 5 sec to start. I like my street power automatically shutting off inverter and or generator.

You definitely can't trust the inverter display unless you calibrate it with a different source.

If it's a simple 4 light, system read what it means for each light to be lit. 3 lights may indicate 75-90%...
Get a hydrometer, use a hydrometer to determine the state of charge (SOC)

With a large load voltage can fluctuate a large amount, this particularly noticeable as the battery's capacity is reduced as the load represents a large % of the remaining capacity.
The 44v is to manage short surges and voltage drop in the cables. much more than 20 or 30 seconds, the inverter shuts down to protect itself, not the batteries. The inverter's job is to provide as much AC power for as long as it safely can, it cares nothing for your batteries.

What puzzles me is there is reference to having street power which I would assume is grid, then reference to generator charging, why on earth would one utilize anything other than grid if available? Both batteries and generator are very inefficient means of providing energy in most cases, when compared to grid costs, since the Sigineer appears to be an inverter charger why use a generator for anything other than backup to the batteries during an extended power outage.
Just reading between the lines trying to figure out what it is you're attempting to achieve and having a hard time doing so. Should this be an experiment to understand the limitations of a backup system, I would highly suggest utilizing a battery monitoring system to start the generator at a higher voltage than the inverters self presivation, batteries dead value.

My inverter has a setting on its charger with high power for de-sulferization lead acid batteries. It comes with warnings and no instructions. Should I disconnect the PV charge controller and turn on the high power for 5 min then 5 min cool then 5 min high de- sulferization???
