A source for info on both inverters (12VDC to 120VAC) and UPSes would be
Tripp Lite in Chicago.  They make both these products.  Wayback I worked
there.  I seem to recall that they did not recommend hanging a UPS off a
generator or inverter, but they have new inverter and UPS models since
my time there.  Their website is www.tripplite.com.
