Later inverters (Outback, Magnum) were step waves too, but just more steps, which translates to less trouble. </p><p><img border="0" id="_x0000_i1025" src="http://www.solarray.com/Images/ImagesTGuides/Stepped%20Wave.png"></p><p>Trace SW waveform</p><p> </p><p>I have cured the "washer not running on the SW" once, by adding a capacitor to the circuit.
