Yep. We've fielded dozens of calls asking us about going to one of the solar systems that feeds into the grid. Our question is always, "Is there an battery back-up option to use the system directly if the grid goes down?" Nope. So there you sit with a 4KW (or bigger) generator on your roof and no access to electricity.

As the $$ become available we will go to a solar system, but only with an off-grid capability.
