How an inverter deals with PF seems to vary broadly. For example, the Splendide XC2100 washer/dryer will not work on a Magnum Energy and a few other sine wave inverters. However, it will run on a low cost GoPower or Samlex sine wave inverter. Below is a scope trace of voltage/current of the Magnum inverter & Splendide washer. Upper trace is voltage<br>
<br><br></div></div><div><br><br><div class="im">By adding a 50uF run capacitor inline, it somewhat tames the current phase and the sine wave so the Magnum can operate the washer. <br><br></div></div><div class="im"><div>

<br>Have a client with a new coffee maker that will not run from their new dual outback setup. Has anyone heard of this lately. We have had no problems with appliances and sine wave inverters. What to look for?<br><br>Sent from Jeremy's IPhone. Sorry for typos and shorthand!<br>
