these units are out there from a few suppliers... IMO not for me...
If you had bare slate enclosed trailer and was setting it up or a van,, then ok,, but to integrate or put into a modern RV... not sure.. yes anything can be made to work sort of..
I added a simple solar to my RV, Rv has a transfer switch/genny/inverter/ and a smart chg system that works well with 300ah of batteries..
I put 400watt with a budget 30A controller, adding another 100-200watts to max out controller.. 600watt on a perfect day, parked perfect may give me 30amps at 14.5V... right now at 400watts I get 14-18 amps 90% of the time in the sun to charge for 6-8 hours of the day,, Being in the north east.. mountain sun angle, season etc.. ..
Just sayin, sometimes simple is better,, I dont need blue tooth, I dont want to fiddle, as once it is working and set up,, I barely look at it,,
