I quit selling Staber, as they changed the design substantially over
the years. The last one I had would NOT run reliably on a Xantrex SW+
Inverter. Kept smoking circuit boards. The days of a Staber running
off a Trace U612 are long gone. (I guess they went to the same
dinosaur land that the old Kohler gennys and decent profit margins went)
To your list of possible causes, you should add:
7) Staber has become a finicky appliance that will drive an honest
solar installer crazy.

Jeff,
I have not yet tested the surge in this application. However, I
have a Staber in my own home as well. My little Xantrex SW+2524
runs it effortlessly, even while the toaster and microwave are both
running (breakfast is laundry time). I believe that the Staber
actually uses a rectified DC drive motor, to achieve reversal of
direction and variable speed control. I don’t believe it has much
surge – remember, it found its way into the off-grid market because
it could run on smaller, mod-square mid-1990s inverters.
Thank you for all the responses. It is clear to me that there are a
whole range of possible causes, and no certainty. My main
suspicions are: 1. Bad AC GFCI at the washer; 2. Bad system ground;
3. My installer error in leaving a loose terminal or cable crimp;
4. intermittent short from mouse-chewed conductors or power cord;
5. bad AC board in FX2524T inverter (one Wrench suggested this from
experience off-list); 6. failure in Staber control board. That’s a
lot of options, I know. When I finally go there and fix it
(hopefully), I’ll post what I learn.

Subject: Re: [RE-wrenches] DR>FX Compatibility Problem
Not sure if anyone offered this already - The DR will do a 5 sec.
surge to 6200W the Outback will do a 5 sec. surge to 4800W. This is
common, most mod's will surge considerable more than Sine's, that
is the big trade off other than power quality and tare losses. In
addition I'm very skeptical that the Staber only surges to 11A,
have you measured the actual surge? When I replaced my good 'ol
Trace 2512 (too many appliances disliked the mod. sine) and went to
a Magnum 2812 my washer would kick it out as my washer surged to
31A and the Mag. would do 30! This is a modern Horz. axis machine.
I now have the Magnum and a new Vanner ITC 12-3200W that does a 3
sec. surge to 6400W and will even run my wire welder and air
compressor, both used to be genny only loads.
