So, the MAGNUM fans caused the problem? Since Magnum builds hundreds of thousands of Inverter's IF the magnum design was the problem, there would be lots of this type problem. FYI, Magnum was started by ex Heart/Xantrex Engineers and they designed and built a much better RV product. I have NEVER seen a Magnum have such a scorch fire problem and I have repaired/replaced probably in excess of 1 hundred Magnums in the past 15 years. Not all factory defects, usually outside 120 power source caused. Doug
What caused the problem was lack of cooling. That could easily be avoided. I suspect Magnum makes millions of inverters.
I spoke to the gentleman in Calgary who authorized the warranty. He said he had seen more than a few burn up. I suspect he sees more inverters in a month than you have seen in your entire career.
I am fully aware of who started Magnum, and also that that team is no longer involved.
I suggest that if the cooling fans were powered by 12 volts and thermostatically controlled, the failure would not have happened.
If I were to start over, I'd go with Victron or perhaps Outback.
The reason for that is my Magnum doesn't always like gfci outlets. Sometimes it is fine, and sometimes it blows the gfci.
I have a patch panel so can easily wire around the Magnum and when I do, the gfci never blows, so it is not the RV.
My friend has a Victron with load support (which I love). It never has a problem with gfci.
I'd also jump to 48 volts instead of staying with 12 volts on the input side.
