  1. Rob,
    This is hard to say without more data, need to know total usage, max current draw, generator size, type of generator, if and how long you want your battery bank to provide power if generator fails.

  2. What a lifesaver. This help me calculate so many things-when it comes to my electricity.
    Understandable and it’s very easy to use

  3. This really sucks, I needed the amount for only 6 hours of use not 1 freaking months worth much less 1 year. It’s a cool idea but is executed atrociously and what is this ugly font???????
