Mine does not have any sensing stuff on it - basic. It is, however, only a 15 watt unit. Running all night long is just right to top off the battery but not to overcharge it.
I have mine on board. It's on the side, between the air intake and the fender. The intake box separates it from the main engine compartment. Also, it only cost me $7, so I can replace it if it fails from the heat.
Quick, dirty, works. If you want the elegant solution, Daox has that covered.
