Check to make sure the inverter is not on search but I stead "ON", next if you turn off the enphase the the outback perform normally. Check the inverter frequency to see your frequency is shifting have one that has both AC & DC Coupling and no issues.</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Aug 25, 2020, 6:37 AM <<a href="mailto:drake.chamberlin@redwoodalliance.org">drake.chamberlin@redwoodalliance.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hello Wrenches,<br>
<br>
An AC coupled arrangement, with an 8 kW Radian and 8 Enphase <br>
microinverters, pulses lighting at low levels of array illumination. <br>
This is generally not too much of a problem.<br>
<br>
Under certain levels of solar isolation, the pulsing becomes extreme and <br>
causes the motors in the refrigerator and air-conditioner to pulse, <br>
sometimes causing very audible vibrations.<br>
<br>
Will this harm the appliances? Is there anything that can be done to <br>
moderate or stop the pulsing?<br>
<br>
Thank you,<br>
