Re: OT - Simple Disconnect/Isolation Switch I think that the only acceptable solution is a Grid-Tie Inverter fed by your PV system. These Inverters can also have provision for a generator input.
They are not cheap or simple but the Power Company will not have it any other way. You will need a permit and a Master Electrician to sign off on the installation or you could face legal penalties.
