IIRC, the name Xantrex was bought by some Chinese conpany around 5 years ago.
This makes sense to me, beceause I know a lot of "xantrex" stuff has a lot of bad reviews and all of the original "xantrex/trace" gear is now produced and branded snider electric, the people who make square D.
I would look into if it is snider electric, or branded xantrex. If it is the later I would pass.
