I am not sure it would ever pay for its self.
You are talking thousands of dollars of batteries, that need to be replaced every 10 years or so.
What is the difference between the low rate and peak rate?

I have a feeling when rates are high, it might be in the middle of the day, so grid tied solar should be cheaper and more effective.
