That's about what to expect from the Psuedo Sine Wave that the SWs put
out. They shortened the list of problem appliances significantly
compared to "mod sine", but its a stepped pyramid wave. Later inverters
(Outback, Magnum) were step waves too, but just more steps, which
translates to less
Hey Wally ! This is definitely truth when adding loads improving the
waveform of the SW.
My friend could make his 2 SW's charge his Chevy Bolt by turning his
oven on in the kitchen.
The stray inductance along with the higher load current I think is what
is doing this.
Time = L/R in s
One detail I recall is that the SW’s “mayan temple” waveform improves as the
load on the inverter. increases Of course the battery capacity may suffer if
an otherwise unneeded load is utilized to achieve this result. If it achieves
it at all. A low cost test option in any case.

Chris, I just helped a friend with his EV (Bolt) not charging from two
stacked SW5548's...
The problem is usually those darned sharp edges created by the 3
modified square-wave inverters in series.
I guess technology is going backwards for this kind of stuff ? New
electronics designers I g
I would do a load test on the inverter. It may have a damaged FET or
two. They do not last forever! Good Luck

New washing machines are small loads 400 Watts about.

I once used a ferro-resonant transformer to clean up a sine wave. You have
to know the power.

Hi folks:
I have a fellow with a Trace SW5548, purchased from us in 2001. It's been
working great for him all this time, but the dilemma is he's gotten a new
Hotpoint washing machine, and its electronics don't like the old inverter.
Is there some sort of power conditioner or 'line tamer' availa
