Just be careful that whatever you do doesn't create a back-feed hazard where you're pumping generator power into the utility line coming to your house. Linemen have been hurt and killed when they contact the back-fed line that was supposed to be dead.
Not to mention it would destroy the generator. This is intended to be an isolated system.
Let me make sure everyone understands the danger there, when the home generator backs feeds the damaged utility lines at 120v?, when that power reaches the first utility transformer, it can get stepped up to from 5,000 to 22,000 Volts or higher, and that can sure hurt a lineman, or a kid playing in a water puddle with a nearby hanging powerline, that was "off" minutes earlier. Additionally, everyone wants the workers to get their power back on as quickly as possible after a storm, but it only takes one careless homeowner to energize a whole neighborhoods damaged power grid, and the workers have no idea who the jerk is, so don't be one.
