In this post I will show one aspect of my portable solar solution, namely how I keep my Genasun GV5 safe when backpacking, going portable, going /PM.
I chose the Genasun GV5 since it does NOT discharge my battery at night, has a small form factor and is an MPPT controller:
I have it hooked up to a Powerfilm Solar rollable panel:
since they are waterproof and I happened to land a good deal when I bought it. But even with "standard" prices, they are highly competitive.
This is all connected to a A123 Energy Solutions Nanophosphate 12V battery. I chose it for it's weight, integrated charge controller and for it's cycle life (compare carefully to other Li chemistries, there ARE differences):
One thing though: the connections of the Genasun GV-5 to the rest are a little tricky, since it's connections only really lend themselves for a fixed installation.
Thus, I made myself a little box (out of a sturdy but flexible plastic food container) with bananaplug sockets (I prefer them over Anderson Powerpoles, but that's another story and one man's meat is another man;s poison...), so I keep the GV5 somewhat protected in the box and have fast connect/ disconnect to panel and battery.
