    You say that you use your system 4 to 5 hours a day but dont say what for. 12V or 24V? Capacity of your charge controller? Your usage will determine what XXXah batteries and how many to get. I use AGM for my off grid system, its for a portable generator, and it works excellent. Sealed AGM is what ive used for the past few years and deff. No complaints. Believe it or not, Universal Power Group makes an excellent deep cycle AGM that is usually more cost effective than other brands in their 12V configurations, they also have really good 6V high ah batteries that configured a few (2 or 4 ) in parallel would be great for a small off grid generator.
