What batteries for an off the grid system?
Hello I am looking for help to decide what batteries to buy for an off the grid system? Since this will be installed on a ranch where I might spend a month without visiting from time to time, and the batteries will be inside the house, I am looking for a non maintenance type off battery. I was given the suggestion on buying 4 fullriver DC224-6 sealed AGM or 4 centennial CB6-224 Sealed VRLA AGM. I have seen the possibility of buying 2 fullriver DC400-6, I know it will have lower Ah, but will it make a difference to have 2 415 Ah batteries in series to having 4 224 Ah batteries (this will be connected to make 448AH)? This system will be used to operate a refrigerator, about a dozen light bulbs and from time to time a sealing fan, it was calculated to use 1,300 Whr/d.
