1. Retired, don't use the PC for work, do use a Samsung chromebook... about 35-40w. And it does charge on 12v. Battery life is extreme on it, 6-8 hours, more than I can surf.

3. I want this system to be portable, not a permanent mount system, I've no idea how long I will be keeping my current Travel Trailer, might want to upgrade, next owner might not want a solar system.
4. Is it worth it to get off the PWM type of voltage controller, considering I might later go to the GC-2 type of 6v batteries that are 225-240AH total, wired in series?
