"I use AGM batteries to store my solar. They are expensive, but last a long time if you don't discharge them continuously."

Great choice! You don't have to bother with the venting issues. Much cleaner, and AGMs are certainly heavy duty (as used in aircraft)! They're the best! I seriously considered getting some Concorde AGMs but went lower cost with the Crown lead-acids in order to be able to afford some other needed components before the dangerous winter here. So a complicated, custom, home-built venting system was needed (high winter winds here).

Really, if the cost of an array of AGMs is assessed over the lifetime of the array, it's not bad at all. Works out to a low monthly.

Thank you folks. I’ll keep you in mind if I have more questions. Appreciate the input.
