Nothing available on Magnum site so went to Amazon and ordered one for about $15. I don’t see why that won’t solve the problem instead of paying hundreds for a new inverter.

The inverter factory programming disables the power on off function. It's meant to always be in search mode. You can turn it off using the inverter battery disconnect switch in the battery compartment. Or you can do what I did and program the switch to work. See the attachments regarding programing.
Set to PS4 for the power button the work.
