<div dir="auto">Ray, I don’t have too much time into troubleshooting, but I have confirmed that inverter AC output readings on the RC are suggesting steady voltage and frequency but my meter readings are showing voltage from 108-135VAC per leg and 60-95 Hz with or without loads. It sounds like a bad AC relay, but I haven’t put in the head banging against the wall effort to track down tech support that the previous installer had. </div><div dir="auto"><br></div><div dir="auto">I agree, a THD would be a good next step.</div><div dir="auto"><br></div><div dir="auto">Kindly,</div><div dir="auto"><br></div><div dir="auto">Chris </div><div dir="auto"><br></div><div dir="auto"><br></div><div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, May 31, 2023 at 5:06 PM Bradley Bassett via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org">re-wrenches@lists.re-wrenches.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div dir="ltr">Just so you know, AEE Solar still has a bunch of Magnum panels and controls, no inverters, no support though.

I've not seen a Magnum have power quality troubles, but they are not the "grid" either. My experience is that they are similar or a bit better than Outback, but certainly have measurable THD in the 4 to 5% range. Its almost always finicky loads, and the inverter has always been within its tolerances, so I doubt you have an actual warranty issue. However, I have seen inverter output get strange after lightning damage, which is not covered under warranty either. <u></u><u></u></p><p>You need a decent meter that can measure THD, and can capture the peak voltage of the waveform. A good oscilloscope is even better, so you can see the waveform. <u></u><u></u></p><p>Stuff like clocks not keeping time, or certain digital controls on certain appliances not functioning, is not a warranty claim. Lights dimming, or LEDs flickering is not a warranty claim. These are normal living off grid, and the only thing better than a Magnum for power quality is Exeltech in my experience. <u></u><u></u></p><p>Ray Walters<br>Remote Solar<u></u><u></u></p><div><p class="MsoNormal">On 5/31/2023 11:37 AM, Chris Sparadeo via RE-wrenches wrote:<u></u><u></u></p></div><blockquote style="margin-top:5pt;margin-bottom:5pt"><p class="MsoNormal">Hi all, <u></u><u></u></p><div><p class="MsoNormal"><u></u> <u></u></p></div><div><p class="MsoNormal">I have a client with a Magnum MS 4024- PAE inverter.
