Recently we had an issue with a Radian system at about 10,000'. An 8048 inverter screaming (fans running hard) with just 2000 watts of load. I hounded tech support for two years, and even after switching power modules, etc in the end the techs claim a fairly substantial deration (that I can't quote right now) of inverter performance because of cooling issues. We ultimately added another inverter to the system at the end of last summer. I hope this season we will see a better result. It makes sense, given the difference in air density, but I do scratch my head and wonder why we haven't seen such issues with the older FX's, and some of the older legacy systems?<u></u><u></u></span></font></p><div><p class="MsoNormal"><font size="3" face="Times New Roman"><span style="font-size:12.0pt"><u></u> <u></u></span></font></p></div><div><p class="MsoNormal"><font size="3" face="Times New Roman"><span style="font-size:12.0pt">I also know that the Midnite classic charge controllers seem to run the fans quite hard as well.

Of course, the specs vary from component to component. I've seen some rated as low as 8000 ft to some as rated as high as 30,000 ft. It really just depends on the part(s) that the manufacturer used to build the product. <u></u><u></u></span></font></p><div><p class="MsoNormal"><font size="3" face="Times New Roman"><span style="font-size:12.0pt"><u></u> <u></u></span></font></p></div><div><p class="MsoNormal"><font size="3" face="Times New Roman"><span style="font-size:12.0pt">As you gain altitude the temperatures and the air pressure decrease, as it was explained to me years ago the problem is with the temperature decrease, this will affect the capacitance of the capacitor. The colder temps will reduce the overall capacitance of the capacitor, just like it will with a battery. <br><br>These caps are generally used to filter noise from circuits, so when these fail, or the capacitance values fall, you don't get the filtering you need and this induces noise into your circuitry possibly causing overall failure or worse, the dreaded intermittent failure. Generally, if the inverters/controllers are kept on and warm, you won't have too many problems, it's when they are in extremely cold temperatures is when you will start having issues. <u></u><u></u></span></font></p></div><div><p class="MsoNormal"><font size="3" face="Times New Roman"><span style="font-size:12.0pt"><u></u> <u></u></span></font></p></div><div><p class="MsoNormal"><font size="3" face="Times New Roman"><span style="font-size:12.0pt">Hope this helps!
