Excellent info Craig!
Perhaps a combination of a much smaller inverter and a large
generator would provide some redundancy.
If the generator were to fail one would have some access to
AC power from a vehicle.
Will watch for a reasonably priced generator - once I am
able to sell some spare Ham gear - market is tough out there.
