I am just planning on where to put the solar controller, I have a choice of it going under the seat base in the rear with a 1 metre cable run to the battery or in the wardrobe with a 3m run to the battery, the instruction state that it should go as near to battery as possible but i am concerned about the lack of air circulation in the seat base, do these things get hot? I am getting the ep solar one like trikeman has in his install blog.
