12v 100ah x 4 maximum charge current and MPPT ?

[8milimeter]

I plan on using 4 - 100ah 12v lifepo4 batteries in parallel for my backup power.
What would be the maximum / appropriate size 110v battery charger current ?
I would like to have 800 watts of solar, would 80amp MPPT controller charge current be to high ?

Thanks, Richard

400ah of lifep04 can charge at 200 amps easy. I would charge at 80ah to be gentle on the battery.

800 watts of solar

800 watts of solar needs a 60 amp rated unit, typical charge voltage will be 13 5 to 14.0 over most of the charge cycle.
Recomend Victron 150/60 .
For AC charging , Victron IP 22, 30 amps
