I haven't looked at what the FXR does to the waveform of a 3000-watt
Honda, but I have used an oscilloscope to look at the waveform of a
small generator while an FX inverter is charging batteries -- it
pretty much makes an ugly mess of the voltage waveform. Not
surprised to hear that some loads don't like to operate when the FXR
is charging batteries from a small generator. The FX charger has a
poor power factor and little filtering of the current waveform, it
is a tough load on a small generator. The generator responds with
lots of harmonic voltages and high frequency noise.<br>

<div>My curiosity was piqued by a recent customer complaint.
I'm hoping someone has bumped up against this issue before.</div>
<div><br>
</div>
<div>The customer has a OB FXR2812 and a 3,000W Honda gen. <br>
</div>
<div>Her gas clothes dryer runs just fine off the OB inverter.</div>
<div>It runs properly on the Honda gen (when the inverter is
bypassed)</div>
<div>It will not run when the gen is on and battery charging is
taking place.</div>
<div><br>
</div>
<div>All the other AC loads (including the washing machine) run
properly during battery charging with the gen.</div>
<div>The OB inverter replaced an old Trace unit. The dryer
worked as it should with the Trace during battery charging.</div>
<div><br>
</div>
<div>Any thoughts are greatly appreciated. Thanks in advance!</div>
