[RE-wrenches] Power conditioner for Trace inverter

[Ray]

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 trouble.

Trace SW waveform


I have cured the "washer not running on the SW" once, by adding a 
capacitor to the circuit.  I can't recommend it 100% from a safety stand 
point, but it worked for us. Some body else chime in on the possible 
dangers?  Cap blowing, fires, shorts?  Definitely needs to be in a metal 
enclosure.

I think its either get a different washer or get a different inverter. 
At 22+ years, its slowly reaching the time to retire those old SWs.
