You seem to have a permanent grid connection and to be using your genny for opportunistic power, rather than as backup for grid failure or for pure off-grid operation.
In that case, why not use an inverter with a "sell" option, feed the genny's power to the grid when its available, and use net metering (which requires NO changes to the existing meter)? That way you don't need a cutover, and you can use the grid to "store" your genny's power when it's making more than you need.
This is even legal and encouraged in most places in the US. B-)
I think there's a federal mandate but I'm not sure. But if your wind genny is under a couple kilowatts and your inverter is UL approved it may be just a matter of making a change to your power account records so they won't charge you for 99999 kilowatthours if you happen to make more than you use some month. Ask your power company for details on how to do it right in your area.
In my area they won't pay ME if I make more than I use (without a separate deal), but they WILL go to annual rather than monthly billing so I can save it up in sunny/windy seasons to use when I nead more than mother nature is providing.
