Because of the remote location of the generator and transfer switch, we can not easily connect on the grid-side of the transfer switch as we usually do (without cutting a very long trench.) So we're looking for a way to lock out the solar during generator use. And then, ideally, reconnect the solar automatically when the grid is restored.
