Mitsubishi PM50B4LA060 is the IGBT module part number. You can see the module in the first photo above poking out the bottom.
These inverters were popular 10 years ago, somewhere around 2009 to 2011. Apparently not very reliable according to installers but that's anecdotal.
I have managed to find quite a few in Melbourne but need another 4 or so.
