electronics component UL certification
electronics component UL certification
(OP)
Folks, I'm building a power board and a control board for an obsolete inverter. The inverter has an input of 24V and an output of 120VAC. It's a very popular inverter which has a long history of use in the Motorhome industry. It is not grid tie. The oldest of these inverters is exceeding 25 years and power board failures are becoming more and more prevalent. There's clearly a market for my aftermarket boards but I'm not sure what type of UL or similar certification might be required or how to proceed. For instance, would UL be interested in testing my boards within the OEM's enclosure? How do folks typically go about offering aftermarket electronics boards and components for obsolete products?

I'd also expect a certification to cost about $20k~30k.
You'd also go to all the bother only to have some ebayer under sell you by a lot since they aren't going to UL anything.
I'd suggest building a solid, safe, protected, drop in replacement and selling it on - Ebay and Amazon type places yourself. If people want to repair their inverters they can buy your replacement and be back in service. Don't discuss the UL ness of it. If they're dead set on having UL they should cycle out their ancient inverter and put in a new UL one.

As you probably know you can't UL list a component, instead it's the backwards UL mark meaning that the component is ostensibly UL listable in a finished product. That means it's assembled with backwards marked UL parts and ready for testing. If you want a UL mark and want to spend for it you could probably get that mark.
