Without knowing exactly how much battery i need...

What would be considered a good size ? 300 AH of Lithium ?
( equal to around 600ah in lead/agm. )

I would size your battery bank based on usage.

I know. But I don't know usage.
I guess, I could wait and after the summer of measured usage, then buy.

Been doing a lot of research.

I think lithium is the only way to go.

A few options.
Agm 190 ah batteries. 4 of them.
That's 760ah total. But. If you go to 80% dod, that's only 152ah.
Cost around $1500.

Lithium. Am solar 400 ah and at a safe dod of 50% is 200ah. ( no problem going lower)
$3200.

So, double the price, double the ah.

But then there's the weight.
128lbs for lithium, and 500 for Agm.

The lithium should last better than twice as long too.

So, the double price equals out?

My head hurts.

Service question.

My sabre has 50A service.

Why?
2 ac. Maybe.
Washer dryer prep ? Could be
2 microwave?
Two fridges?

Anyways.

The magnum has a 60A passthrough. I would like to use it to power the whole rig, as opposed to a sub panel.
Being plugged into 30A service, without the assist from the magnum, can I even run both ac?

Normal loads would be.

Both ac
WH
Both fridge
Can't think of what else.
All lights are 12v led
We don't use microwave

Would 60A passthrough of the magnum work?

Yes. Mag. has 2 30 amp legs and your rig has 2 25 amp legs. You don't need a sub. My Mag. Has only 1 30 amp leg so I used a sub panel and pulled the circuits I wanted the inverter to power. In your scenerio you would have to be mindful of what you are truly powering when inverter is on. Not that you don't have enough juice. But it would not make sense to power the electric water heater or run the ac. The sub takes that thought process out of the equation for me.
