I guess I question to know why a 24-volt solar system is good for RV applications..
We all know solar panels do not work standalone and the sun energy has to be stored in batteries for us to use them in our RV trailers.
It is easy of course to series a couple of 12VDC batteries but the resulting 24VDC is not really a good component IMO to use in the RV World... 24VOLTS DC is too much power to charge a 12VDC Battery system. I never see anything higher than 14.4VDC here with my setup but I do hear some RV Battery Systems will work with 15VDC charge voltages.
It could be the 24VDC Solar Panel DC OUTPUTS work better with SOLAR CONTROLLER but to me the final DC output going to the RV Battery setup should remain at 12VDC so that you can utilize all of the working elements the RV TRAILERS has to use.
To me this is maybe something one would do at a Residential Facility, not a mobile RV trailer setup...
I understand a higher DC VOLTAGE will make make power better but it just flies against what we RV TRAILER types have to work with.
To me it would just add to the problems to make a 24 VOLT DC compatible with the 12VDC BATTERY Systems the RV trailer have???
Being new to all of this I am probably out in left field somewhere we these comments...
Just reading and learning for my next project of adding SOLAR PANELS to my trailer....
