    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???????

    Gerret,
    You can enter the device, watts, and 6 hours and take the total for the year and divide by 365.25 and you will get the 1 day usage for the 6 hours.

    My monthly use is 1690 kwh per month. What size battery bank will I need?

  9. Go Green In Your Home Says:

    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.
