<div dir="ltr">I have the same problem at my place, and a couple client's systems, with Magnum inverter/chargers and small ~2-3kw generators (not just Honda). But the problem appliance is microwave ovens, doesn't matter which microwave brand. They run fine straight from the generator, and fine from the inverter with no generator running, but make a strange, loud hum, dim internal light, and food doesn't heat if the generator is also charging the battery bank. I'll try to figure out how to capture a waveform photo with my scopemeter and post it.<br clear="all"><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div style="margin:0px;padding:0px;border:0px;font-stretch:inherit;font-size:12pt;line-height:inherit;font-family:Calibri,Arial,Helvetica,sans-serif,serif,EmojiFont;vertical-align:baseline;color:rgb(0,0,0)"><span style="margin:0px;padding:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;font-stretch:inherit;font-size:12.8px;line-height:inherit;font-family:Arial,Helvetica,sans-serif,serif,EmojiFont;vertical-align:baseline;color:rgb(34,34,34)">Dan Fink</span></div><div style="margin:0px;padding:0px;border:0px;font-stretch:inherit;font-size:12pt;line-height:inherit;font-family:Calibri,Arial,Helvetica,sans-serif,serif,EmojiFont;vertical-align:baseline;color:rgb(0,0,0)"><div style="margin:0px;padding:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;font-stretch:inherit;font-size:12.8px;line-height:inherit;font-family:Arial,Helvetica,sans-serif,serif,EmojiFont;vertical-align:baseline;color:rgb(34,34,34)"><span style="font-size:12.8px">Executive Director, Buckville Energy Consulting</span><br></div><div style="margin:0px;padding:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;font-stretch:inherit;font-size:12.8px;line-height:inherit;font-family:Arial,Helvetica,sans-serif,serif,EmojiFont;vertical-align:baseline;color:rgb(34,34,34)"><span style="font-size:12.8px">NABCEP PV Associate</span><span style="font-size:12.8px"><br></span></div><div style="margin:0px;padding:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;font-stretch:inherit;font-size:12.8px;line-height:inherit;font-family:Arial,Helvetica,sans-serif,serif,EmojiFont;vertical-align:baseline;color:rgb(34,34,34)"><span style="font-size:12.8px">NABCEP Certified PV System Inspector</span></div><div style="margin:0px;padding:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;font-stretch:inherit;font-size:12.8px;line-height:inherit;font-family:Arial,Helvetica,sans-serif,serif,EmojiFont;vertical-align:baseline;color:rgb(34,34,34)">IREC Certified Instructor\u2122 for: </div><div style="margin:0px;padding:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;font-stretch:inherit;font-size:12.8px;line-height:inherit;font-family:Arial,Helvetica,sans-serif,serif,EmojiFont;vertical-align:baseline;color:rgb(34,34,34)">~ PV Installation Professional</div><div style="margin:0px;padding:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;font-stretch:inherit;font-size:12.8px;line-height:inherit;font-family:Arial,Helvetica,sans-serif,serif,EmojiFont;vertical-align:baseline;color:rgb(34,34,34)">~ Small Wind Installer</div><div style="margin:0px;padding:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;font-stretch:inherit;font-size:12.8px;line-height:inherit;font-family:Arial,Helvetica,sans-serif,serif,EmojiFont;vertical-align:baseline;color:rgb(34,34,34)"><span style="font-size:12.8px;font-style:inherit;font-weight:inherit">NABCEP Registered Continuing Education Providers</span><br></div><div style="margin:0px;padding:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;font-stretch:inherit;font-size:12.8px;line-height:inherit;font-family:Arial,Helvetica,sans-serif,serif,EmojiFont;vertical-align:baseline;color:rgb(34,34,34)"><a href="mailto:dan.fink@greendustrialtraining.com" target="_blank">d</a><a href="mailto:anbob88@gmail.com" target="_blank">anbob88@gmail.com</a></div><div style="margin:0px;padding:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;font-stretch:inherit;font-size:12.8px;line-height:inherit;font-family:Arial,Helvetica,sans-serif,serif,EmojiFont;vertical-align:baseline;color:rgb(34,34,34)">970-672-4342</div></div><br> </div></div></div></div></div></div></div></div></div></div></div></div><br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Aug 15, 2020 at 9:37 AM Kent Osterberg <<a href="mailto:kent@coveoregon.com">kent@coveoregon.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

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>Hello All,</div>

<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>
