Like everyone else said, your power shuts off your canister is going to keep siphoning water into the sump until the intake is above the water line. When the power comes back on your canister won't reprime but will continue to run, potentially burning out, and your pump will run your sump or at the least its compartment dry, potentially burning out also.
You're essentially trying to run an overflow system that will lose its siphon every time your power goes out.
Look for the DIY overflow sticky and read all the way through it. We built a couple and they work well, it will also help you learn how a siphon overflow works and potential problems.
Its also possible to build your own overflow box if you know how to work with acrylic and even if you don't. If you search the net you can find a lot of ideas. If you learn enough about overflow boxes its even possible to figure it out yourself.
From your question though it seems you need to do a LOT more research on overflow boxes before even buying one. Most problems with overflow boxes are caused by lack of knowledge about that type of system. Understanding the concept itself, which is fairly simple once you grasp it, will prevent you a whole lot of problems.
