No! SWs and Outbacks sync the existing loads with the generator before
switching over, so that there's no interruption. They also make the
switch gradually so that the generator doesn't sag any more than
necessary. You might do some homework before posting stuff that makes
how little you know so damned obvious. As if you could ever wise up
after so many years.

So, the end result is the same, inverter protected from reverse

My inverters (Trace, now Xantrex) have an adjustable window for
generator input. It has to be wide enough to accommodate the variation
between the generator's output when it's loaded and unloaded, and when
it sags momentarily if big loads come on line.

Possibly by purchasing appropriate equipment.

I am off-grid with SW5548 inverters, and a 12kW backup generator.  The
inverter tolerance is 53-67 Hz (when syncing to a generator).  The voltage
tolerance is programmable with nominal values of 108-132Hz.

The inverter monitors the output from the generator.  If the generator
supplies out of spec power to the inverter, the inverter disconnects itself
from the generator, until the generator settles down.

It is pretty rare for this to happen.

A neighbor, also off-grid, has an inexpensive 5 or 6 kW generator and a
Trace DR series inverter.  His experience has been similar to mine.
