[RE-wrenches] DR>FX Compatibility Problem

Thu Jun 18 18:14:51 PDT 2009

Thank you, Ray, but this is a 2000 year model. Does your advice apply to the
older units as well?

We had a 1999 model, now a 2002 model in our home; both OK on sine (FX) and
mod-sine (SW+).

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.

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.
