Automatic transfer switches are priceless as far as convenience IMO, especially in adverse weather conditions. I have a 50A ATS for the genny, and a 30A ATS for the inverter. All I gotta do is push a button. I can do that in my underwear without worrying about the neighbors.
Wishlist...a new genny is on it too. Lots of work to get it all set up right. At the present time, everything is cobbled together. I'd love to be able to push a button and be able to switch to genset....or better yet, automatic power failure sensing. anyway, just glad we had one for this storm.
