You can thank terribly written intellectual property laws for that exclusivity. It’s not like inverters are some kind of new technology, and yet here we are.

- londons_explore 3y agoI suspect the inverter design is now cheaper too. The traditional design needs all power to go through a transformer. A 1 kilowatt 60Hz transformer necessarily uses a lot of copper and steel. The inverter design can use MOSFETs (theoretically cheap, but a reasonable IP cost) and far less copper and steel.
