Is there a relatively inexpensive (couple hundred bucks) way to shift about 3kW 110v AC by 180 degrees? The load will be variable between 0 and about 3kW.
This is so I can "upgrade" my home backup generator. Here in the USA our home power is delivered by two 110v lines that are 180 degrees out of phase, and a neutral. Most outlets are 110v outlets, with half of the outlets getting power from each 110v line. Outlets for larger appliances use both 110v lines to give you 220v at the outlet. My current backup generator has outputs just like the utility so it's a direct plug-in.
My preferred replacement generator (inverter type) only has single phase 110v output, so the dilemma is how do I power both sides of my house using only a single phase source?
I'm willing to give up the 220v outlets when on generator power, so I figured my two options are; either shift part of the generator output by 180 degrees and power the house as normal. Or, run the same phase to both sides of the house and be sure all 220v appliances are turned off at the breakers, though I'm a little nervous about unforeseen issues with this method. Does anyone have insight on this?
