[RE-wrenches] DR>FX Compatibility Problem, Magnum inverters

[Larry Crutcher, Starlight Solar]

Hi Jeff,

I am not sure if this relates to your issue but there is an issue with  
Magnum inverters and Splindide washers. Splindide will not work on a  
Magnum sine wave. They are aware of this. Here is a copy of my old  
post to the list:

....I have a recent power issue come up with a Magnum inverter. A  
customer tried to operate her Splindide washer/dryer but the motor  
would not start. I looked at the waveform with a scope and RMS voltage  
and frequency were fine. The waveform looked good until the motor  
tried to start. The washer was putting a jagged noise riding on the  
sine wave. The voltage and waveform still looked OK other than the  
noise. I was mostly sure that this was the cause so I grabbed a 600  
watt cheap import sine wave inverter and connected the washer. Same  
ripple was present on the waveform but the $400 inverter would run the  
washer motor fine. It also runs fine with a 1600 watt Honda inverter/ 
generator.
