[QUOTE=GABoy;826442]24 hours run time has nothing to do with inverter. You'd have to upgrade your battery bank for more amp hours.
X2 GABoy is correct Battery amp hours is the key, just to add to this you should think of everything you are using daily and add up the amp hours being used then match your system including batteries, solar, generator use etc. to determine your needs, if only running the fridge then you need to know how many amps the fridge uses plus how many amps the inverter itself uses (the inverter uses amps to function by itself) then convert to amp hours then install enough battery banks to cover. The other thing you want to think about when upgrading your battery bank be sure all batteries are matching in amp hour ratings and don't add new batteries to old batteries (unless the old are fairly new).
