Maybe someday. Keep in mind that those $100 12 and 24 volt truck stop inverters are something of a special case. They're disposable commodity items probably made in the hundreds of thousands in Chinese sweatshops, with components produced in the millions in other Chinese sweatshops, using reference designs funded years ago by the Chinese government. The cost to set up manufacturing of these is low, and the competition among manufacturers has to be cutthroat. As soon as a manufacturer deviates from the reference design, they have additional costs for design, testing, and certification (if they don't counterfeit the regulatory marks). Component quantities go down, so component cost goes up. Production is lower. Competition is less. So the retail price goes up. It's a fairly safe bet that some Chinese entrepreneur is out there keeping an eye on the potential market for a 200+ volt input inverter. When he sees a decent profit in one, it will get introduced. If it sells well, others will hop on the bandwagon. Then component costs will fall as production scales up, and competition will most likely drive the finished inverter price down into the few-hundred range. Of course all this assumes that 5 years from now the US and China aren't lobbing nuclear missiles at each other, and/or sabotaging each others' internet. If that happens, you can forget the $100 truck stop inverters, too. And that will be the least of your worries.
