Hello, I am new here so be nice. I was looking around for a solution to an issue that has presented itself. We have a couple of generators at our home that perform various tasks. One is a portable unit that we use for emergency power by disconnecting the main and using a back feed method. I also have a large st-20kw head connected to a 25hp mower engine that runs on syngas (wood gas). The other day we received notice that we are getting another rate increase (AEP VA) second in six months. So as we all know syngas will power an engine just as well as gas or diesel so I want to connect the 20kw to our home and back feed to net meter and offset that increase. Only issue is the concern of killing a lineman when the power kicks and the generator is still running. A manual transfer switch will not work because of obvious reasons. Any ideas of an automatic switch that will sever the main (grid) line and allow the generator to continue to produce power for out our then connect back to the main once the grid power is restored?
