Lou,
This was a not-uncommon issue that would occasionally arise with
specific washers and the SW series. It often came up with Y2K
installations. It has nothing to do with voltage /per se/, and the
inverter is working as it should. The SW is true modified-sinewave (with
something like 28-42 waveform steps per half-wave). The problem is that
the electronic controls in the washer aren't compatible with the
waveform. In short, three options:
1- Sometimes a large electrolytic capacitor across the inverter ac
output terminals will work. I have seen it work but not always.
2- Try a different brand of washer.
3. Upgrade the inverter to a sinewave unit.

Aloha All,
I have a client with a old Trace 4024 on a APT center. Everything has
worked great for over 20 years. He purchased a new washing machine
from Sears that does not want to work. The voltage at the outlet is
117 vac and the Sears guy says that is the issue. When the system is
running on the genset (Northern Light 6kW Diesel) we get 121 vac and
the washer runs fine. That seems like a very tight voltage window and
a issue with the washer not the system. I have seen sensitive
electronics go wacky with no N-G bound maybe that is the issue? I did
not install the system so I would have go poke around. Any one out
there have any ideas?
Aloha,
Lou Russo
