I have done a fair amount of research and component selection as I am in the process of adding 400W of Solar to my 2651S which shares some similarities as yours.
I have selected and am using Renogy 100W 12V Bendable Monocrystalline Solar Panels
. They are more efficient, competitively priced and offer a thicker substrate plastic backing than some other Mfgr’s I considered. They weigh 4.4 Lbs each verses 16+ Lbs each for the aluminum framed version. I won’t have to drill any holes into the roof as the Bendables can be affixed with EternaBond WebSeal Tape
Tape. There should be less wind resistance when traveling and the panels can be walked on. They can be removed with careful use of a knife should it be required. They also take up less real-estate on the roof allowing me to add more panels should the need arise. The downside to these panels is they can’t be tilted to face the sun when parked for a longer time and they may not be as robust as the tempered glass versions. I think I have weighed the pros and cons accurately and chose these overall. I also, will be using the Tape to also affix the Wiring run on the roof to the access point at the refrigerator vent.
For the wiring entry into the “body”, I will utilize the opening around the roof top refrigerator vent. I will use AMSOLAR's Vent Combiner Box
and then run 6AWG wire, down the vent and onto the floor behind the cabinets to my Solar Controller. Along this run will be a Circuit breaker to “disconnect” the panels should maintenance be required.
The solar Controller I have chosen is the Blue Sky Energy's Solar Boost 3000i
. It is a 12Volt, 30Amp, 400Watt MPPT Solar Charge Controller. MPPT Charge controllers are said to offer 30% better efficiency than PWM controllers. I will mount this either in the entry way panel where the battery control switch is or underneath and behind a drawer in the cabinetry. I have chosen also, to use Blue Sky Energy's IPN Remote
which includes a Battery Monitor as well as being able to access the MPPT controller or multiple controllers remotely. I am going to mount the Remote to the Entry Way Panel or next to the “Convenience Center Panel" depending on ease of installation. Using this remote, I can easily add additional panels and controllers as our needs may change without butchering up the cabinetry or appearance too bad.
I will run 6AWG wiring from the controller to my LifeLine GPL-27t AGM Deep Cycle RV Batteries
with the appropriate fuses.
I am in the process of purchasing the remaining parts as my Minister of Finance and budget allows and will begin the install shortly……. Stay Tuned for film at 11:00
