No, that's certainly not a good idea.
Anything feeding into the grid has to have a grid impedance check integradted and automatically disconnect when the grid goes down.

In some jurisdictions where grid intertie inverters are permitted, they are to be hardwired in and have a disconnet that PoCo workers have access to.

For my area I know the code for photovoltaic systems. There has to be an accessible DC main switch (accessible just means there has to be a way to get to it, in one case it was via a retractable attic ladder and the PoCo didn't have any problems with it) an auto disconnect and a disconnect means in the main panel (e.g. a circuit breaker). Everything is hardwired.

Trumpy the Super 14 final was played in a ridiculously dense fog. If there was an Australian team in there they would have got lost as they aren't used to playing in low visibility.

Sounds like the switchgear costs required for applications like "Whisper-Gen" to backfeed the grid would make it unfeasible.

Classicsat, how does a Grid-tie inverter work. Is it intrinsically safe for linemen in a power outage ?

I don't think so - all you need is the impedance check circuitry and a contactor rated for the generator load.
Inverters for photovoltaic systems with all devices needed for backfeeding start at 1500 Euros, and most of it is the inverter itself. So... the technology exists and it's approved by the Officials, at least in Austria and Germany.

If we really get the home generator I'll give you a detailed report of course.
And we aren't talking small stuff here - we say 40 or 60kW, not 1200W!
