The main difference between UL listed and not UL listed is the testing they have been put through.  To get an UL listing, devices have to conform to building codes, manufacturing codes, and withstand x amount of equipment specific..related abuse.  How well do they stand overtemperature, how terrible can they be if they DO happen to catch on fire, What kind of electric insulation is on them... stuff like that.

This kind of testing costs money to do, consequently, items that are UL listed tend to be a bit more expensive to cover those costs.  The UL ones might have a different wiring insulation on them, or a different gasket material on the sealing box, or minor stuff like that so that they conform with the standards and CAN get that UL sticker on them.  Then again, the UL ones might be exactly identical to the NON UL ones, just that they have not been 'formally' tested, so can't get the listing.

Quality wise, the UL listed product will be the same, if not slightly better than the non UL products.  Both produce the same power, and have the same warranty on them.  If you are doing some sort of setup requiring building inspectors though, then yep, you will have to spend the little extra cash to keep the inspectors happy.

BTW,I do own 6 of these panels, and love em.

>I believe bergey either sells one now, or is getting ready to sell one in the very near future that is grid interactive.  If I am not mistaken I think it will be along their XL-1 line of turbines.

A few places you can look are Lindsay Publishing company, they have a TON of books on that very kind of thing....

also, a web page, amazing devices or interesting devices . com  something like that gets into this kind of stuff too.

I already have an inverter, but, if you can not sell the set, Id be interested in buying the air 403.   Give me a quote if you are interested.
