Your best bet might be recycling someone else's unwanted junk. Scrap metal merchants and the local rubbish dump may turn up something if you are both patient and persistent. Phoning around some of your local solar installers may turn up a deceased grid tie inverter that is not economically repairable. That sometimes happens because the company that made it is no longer in business and there are no circuits or information. They would usually be more than happy to get just scrap metal value for it.
