The 12V output is to charge batteries only, which are external. It isn't intended as a PSU. Plus, even if it were, it's only rated to 20A. It has the 120V "input" only to charge said batteries, and act as a feed-through when AC power is available. Besides, $440 is a bit much for a 20A PSU. I guess if you NEED a backup supply for your shop it would work. You would also need a 12V battery to hook it to, then just use that battery for the 12V power.
