Friends:
I had an experience with a more modern inverter system creating harmonic distortion on the output waveform during generator run. That issue was documented here <https://millersolar.com/MillerSolar/case_studies/25_GFI%20Tripping/GFI_Tripping.html>. The inverter system is Outback Radian. A few weeks ago I received a call from an individual that was researching a similar problem. He called me to tell me he had resolved his harmonic distortion problem by installing a 20 microfarad capacitor in the circuit that was having problems. I have read here about adding a capacitor to solve distortion problems. The same client is still having problems running a modern oven. I ordered a 20 microfarad, non-polarized capacitor rated at 440 VAC. I will let you know if this provides any resolution.

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.

It's been working great for him all this time, but the dilemma is he's gotten a new Hotpoint washing machine, and its electronics don't like the old inverter. Is there some sort of power conditioner or 'line tamer' available that will work for this appliance's operation? Any ideas would be greatly appreciated. He's rather loathe to replace his inverter if he doesn't need to.
