I appreciate the input Jetsam, I assume they make the same kit for NG? My only concern I need a system that will recognize that the power is out, and then turn itself on. I already have a back up pump mounted higher in the sump pit and a spare sitting next to the sump. I never realized how much it could run until we had a very rapid thaw one spring. I remember back in the day, you could tell if your power was out by calling your home number and if the answering machine picked up you had power
That's possibly out of scope for something you can put together yourself for cheap.
The rub here is that you need a device that both watches for the power to go down and locks out utility power, then starts the generator. If you made such a device, I have to imagine that it would draw wrath from any building inspector, even if it was well designed and implemented.
Happily, you can buy one off the shelf (it's called an automatic transfer switch), but they can be expensive, and if you want to avoid a lot of head scratching and hardware hacking, you may want to stick with single-manufacturer generator + ATS systems.
So yeah, for what you want, possibly best not to try to go as cheap as possible.
