<p>Many of these issues also were solved with an inverter that had gen support or load shave.</p>
<p>Time for a new inverter or a generator that is twice the load wattage. This was common back in the day and as Steve said, some cases just can't be fixed. Another reason many have abandoned 12v inverter/chargers except for RV use.</p>

<div dir="ltr">Wrenches, <br /><br />When the inverter charger charges the battery bank and runs loads this can affect the harmonics of the generator output. <br /><br />Not much you can do about it other than putting in a larger generator to handle the inverter/charging load along with the loads of the system, and even in some of those cases depending on the generator dosn't even fix that. <br /><br />I have seen some successful with filter caps on the output / Input of the inverter, but that is pretty hit an miss..

<div dir="ltr">I've seen that same issue too. I assumed that the battery charging, house base loads, and the microwave were too much power for the small generator. The voltage drops big time which I assume is what was causing the issue with the microwave and most likely with the dryer too. </div>

<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>Matt,<br /> <br /> 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 /> <br /> Kent Osterberg<br /> Blue Mountain Solar<br /> <br /> <br />

<div>Hello All,</div>
<div> </div>
<div>My curiosity was piqued by a recent customer complaint. I'm hoping someone has bumped up against this issue before.</div>
<div> </div>
<div>The customer has a OB FXR2812 and a 3,000W Honda gen. </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> </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> </div>
<div>Any thoughts are greatly appreciated. Thanks in advance!</div>
