pushing a unit is the way to break it, sure it will work but for how
long.

Well, Yamaha says it will produce 3500w for 3 seconds. In the manual they
say it will simply shut off in event of an overload, and they don't warn
about overload breaking it. So, it seems likely that 2000w for 2 seconds,
without the genny shutting down, won't damage it

| Most likely neither the windings nor the inverter electronics will actually
be the limiting factor. All generators use some form of circuit breakers
and/or fuses to limit both the continuous current delivered as well as the
transient surge demand which is imposed by big inductive loads like motors,
etc. The breaker / fuse is deliberately chosen to protect the inverter /
windings / etc.
Unless somebody is deliberately trying to circumvent this design by either
putting a jumper across the breaker/fuse or repeatedly overloading the
circuit and flipping the breaker on manually, the generator should know how
to protect itself against the common start-up demands which typical
appliances demand.
It is entirely possible though that the generator is designed and fused to
only deliver a very small amount of extra transient surge current above its'
normal steady state continuous rating. In this case, the 'fridge' could blow
the breaker every time it cycles on its' compressor, if the generator is
undersized.
