I have been peaking through the Carmanah website looking at their solar-system offerings and I am fairly impressed with what I am seeing. Lots of choices and the ability to mix / match to meet my needs. Their main-site is at: Carmanah - We put solar to work. Carmanah.com I started looking at their site because of their RV stuff. Their "Solar Elite and Weekender" will allow you to run 110v equipment directly from the solar panels (given sufficient light). They also have ""solar charging systems" that you connect to your battery-back-up systems (deep-cycle) to power everything in a 12-volt world. For my little tent-trailer, the solar-charging-systems with dual 6-volt deep-cycle batteries would probably be more than enough to keep me happy for an entire summer of camping without needing to bring my gen-set along. Does anyone here have the Camanah solar stuff - and - if so - any problems with it (either self-inflicted or design) and what have you done to rectify the issues? When I build my "off-the-grid" house, my plan is to use the "full-time RV solar systems" (Elite) to run the house (which is planned to live on 12-volt primarily, not 110v).
