Yea you would think the company installing the solar system would have designed that into the system.:banghead:
You can buy inverters now that run both grid tie and off grid in one inverter so that when the grid goes down you do have back up power. My system was before they were out. I do have 8 Rolls batteries and 4.2Kw of back up power from my panels. It's not really a problem, I never use my back up system as the interities covers my electric bill plus. I got the extra panels to help heat my house in the winter. I could flip the interite over to help with my needs but it was a grant and it would be unfair to the power company who generously gave me the grant for the intertie.
Last year when my area was out for a week I loaned out my generator as I didn't need it.
