Yes, UL listing to sell something is not necessary. 

Back to inverters. Be careful buying non UL Asian inverters. A lot of them
do not have a neutral to ground tie. You will find instead that the ground
prong or green wire is actually tied to the center tap of the output and
that NEUTRAL is 60 volts from ground and that HOT is 60 volts from ground.
Some would say this is actually less deadly. I won't call it as to
contradict UL is, well not sanctioned? If you know that this is what you
have and properly deal with it, then fine.

UL (Underwriter Laboratories) is an independent agency that was founded by
insurance underwriters who were losing money due to fires caused by home
electrical appliances It promoted itself using scare tactic ads on TV that
displayed TV sets catching fire and burning down homes.
