I don't see the point of battery backup at all unless the solar system is off-grid entirely. A generator is a couple hundred bucks new. Who cares if it burns a gallon of fuel every other year?

The only way I see a battery as useful is to game TOU pricing to charge them up when electricity is cheap and discharge when they are paying top dollar for electricity.
