Hi Wendy,
220 is the total capacity--but you can ONLY use 110 of that if you wish the battery bank to have a long and healthy life. Parasitic loads on a typical RV are 25 to 35 amp-hours per day. 110-35 = 75 amp-hours to play with.
So 220 is.......not very much.
I'm an energy HOG and use as much as 300 amp-hours from my 875 amp-hour bank per day.
