Short of modifying your existing system (or better yet, building your own system that will better work for you....panels and a controller are super cheap these days), I like the idea of having two different length cables that you can mix and match as needed. Just keep in mind that every time you have a connection point there is an increase in resistance.....and a corresponding voltage drop.
But, keeping with my theme of looking for alternative solutions (I guess they call it thinking outside the box) here are some more (dumb???) ideas:
- Get a second portable system that you put in parallel with your existing system and double the fun of chasing the sun around.
- Have a second battery that you put right by your panel, then swap batteries as needed. If you can't bring Mohammad to the mountain, then move the mountain to Mohammad...or some such nonsense.
- Put another cable in parallel with your existing cable.
