I'm building a solar system for my RV travel trailer...and need some help with battery sizing.
Configuration so far:
Six 100 watt HQST Poly panels configured 2S3P. (Planning for shade in campgrounds)
Victron SmartSolar MPPT 150/35 Solar Controller
WildKat 55 amp charger converter
Renogy 2000 watt inverter
Go Power Transfer switch
All running 12 volts
Lots of 1/0 wiring.![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
My energy usage calculations are 100-162 ah per day.
My question is what size batteries should I go with...my plan is to have 2 Lifepo4 batteries wired in parallel for a 12 volt system.
My choices are 152 ah, 200 ah, or 280 ah batteries (times 2)
I am leaning toward the 280ah ones...my question is...is there such a thing as too much battery?
My concern is with my configuration can I charge them back fast enough...or am I wasting my time and should go with smaller batteries?
Thanks in advance.
