Would this be enough in a power outage?

Ack that thing is pretty expensive for what it is. The "spec" sheet is pretty awful so I'm guessing a bit but I doubt that unit puts out a true sine wave. Your pumps may run properly on it they may not. I picked up a 450VA (~230W) APC unit at Costco for $35 last month, just go get a couple of those.
