Cheryl,

Running the roof air can be done via the inverter and battery bank. The real question is "how long". When I had 875 amp-hours of battery bank I could do it for about an hour. Then the bank had to be recharged. On my (now tiny) solar system that would take about 7 days.

To successfully run the roof air, 10,000 watt hours of LI battery bank would be needed. For me, that is not going to happen because I can't possibly afford it.
