more batteries or less?

Beware the dead battery trap. Hammering batteries leads to hammered batteries, which leads to lots of  experience with hammered batteries. Ones perception of normal is no longer normal.

right now my inverter shuts down at 24.2. i run it from 12-8 am. then at 8 am i run my 20k generator till noon,
 then 6-12.

my loads when the generator is on is about 60 amps. and when the inverter is on i run about 7 amps-running tv,sat box, a couple of box fans, and sometimes a fridge.

With 200 posts here you know the drill, right? But a few alarm bells ringing a bit here. Maybe add your system to your sig, so we dont have to guess the rest of the system.

So is there no solar, you charge using the genset, then run off the inverter to get a rest from the noise,and repeat?

A quick refresher on the rules:
- recomended overnite DOD 25% for best value for life on the batteries.
- In your situation you can push this to 50%, because there is no reserve requirement.
- NEVER let the system run til inverter shutdown, that will kill batteries quickly.
- 0.1C charge rate for FLA
- 100% charge required at LEAST once a week.
- just big enough inverter
- just big enough genset.

If we assume your daily loads are, say: 2kWh/day. Then, the size battery you need is 2kW/d / 0.5 = 4kWh or
166Ah at 24V. (For the sake of the illustration we'll round that up to 215AH - GC2.)

To charge this, to get the best fuel economy etc we want to run the genset at the peak charge rate for FLA which is 0.1C: so charge rate is 215Ah*0.1 = 21.5A. So genset only needs to be 24V*21.5A/0.8 (eff) = 645W, and will run for =10h*0.5/0.8= 6.25hrs. Thus a 1kW genset allowance plus whatever else you need to load it up with 3kVA gives you a couple kW for day time loads.

You can see how in this scenario using a battery with a higher charge rate capability would radically decrease your charge time. If we were to use one of the lithium chemistrys, 0.5C for LFP, or 1C for the lithium nickel maganese  batteries used in EVs. That reduces daily genset run time from 6 hours to sub 1 hour.  Soemthing like a crashed nissan leaf battery is pretty cool. Still not cheap, but you can sell the cells you dont need and come out square. Or else AGM is still going to be help with 0.2C charge rate.

Either way you dont want to do daily absorbs with a genset, becasue the amps taper and you waste fuel pointlessly. So bring to up to the absorb voltage and stop there for 6 days, and on the 7th day, complete the absorb plus a 2 hours of float, to top off the SG. And for this a small solar addition, even a single panel could be used to do final part of the absorbs.
