TWO batteries and haven't made the switch (and LARGE investment) to Lithium Phosphate batteries. With this current system, sized for two group 31 batteries with 130ah each) and using around 80 ah each night I was at 80% charged before 11AM each day! Because of the design of the charger and the nature of flooded lead acid batteries the last 20% takes much longer. Mine is set to about 3 hours (absorb) before it goes to "float." That's how the charger is programmed and it protects the batteries and extends their life. Well, that is if you care for them properly!

I am a firm believer in solar power. You could use it RIGHT NOW! Without really sacrificing anything at all. If it gets too hot, you could still start your generator (I'm not quite ready to give that up yet!) The costs have dropped significantly and a usable system including all parts can be had for about $2500, if you install everything yourself and then set it up properly. Once all that's done, it really is self working. You still have to maintain your batteries with distilled water....but maybe when Lithium gets a bit cheaper....that will become a thing of the past as well.
