Also, are the cables specific to Grape systems, or are they standard of the industry?

Answer: 
Grape Solar's 400 watt kits include a set of parallel cables to tie the four panels together. The panels must be adjacent to each other in a single row with portrait orientation, otherwise additional MC4-to-MC4 cables may be required. The kits also include two 15-foot MC4-to-MC4 cables, and a 6" pair of MC4-to-bare adapters (to tie the cables in to the charge controller). All MC4 connectors should be Read More

Answer: 
Sometimes I recommend that people buy a single 15’ MC4 cable and cut it in half to get two leads (+ & -) that go from the solar panel to the charge controller. When you cut the cable in half, you will need to strip back the cut ends about half an inch to fit into the terminal blocks on the charge controller. If you are unsure on anything, give Grape Solar Tech Support a call at 877-264-1014.

Rated 3.8 out of 5 by 6 reviewers.
Rated 1.0 out of 5.0 by Misleading product Add If you purchase a solar panel from Grape off the Internet and order their extension cable you will get only a single (1) wire not a cable as defined by Webster IE..."a group of wires, glass fibers, etc., covered in plastic or rubber and used to carry electricity or electrical signals".. This product add is very misleading if you can't physically see it first hand. Very displeased when I went to install 3 panels and discovered this was only a WIRE and not a cable. I will be returning return the 3 so called cables I purchased and use alternate means. $16 for 15 ft of #12 wire is way overpriced. Also wire size in their cable is small if you plan to put the controller any distance May 16, 2016
Rated 5.0 out of 5.0 by Critical Accessary Get two (one each for + & -) of these, unless your setup allows the panel to be within 20 or 30 inches of the charge controller. I park the RV in shade but can still collect solar with the panel about 12 feet away. July 10, 2014
Rated 4.0 out of 5.0 by Part of a larger purchase. The description needs to be updated to indicate that you will need two of these. Otherwise very pleased. July 1, 2014
Rated 4.0 out of 5.0 by Definitely need an extension cord. Found out that need 2 of these, the one is not enough. The cord connected to the solar panel is very short. April 16, 2014
Rated 5.0 out of 5.0 by Excellent, but you need two This is very good cable, but being inexperienced in such matters I thought it was dual-wire cable. It is only one cable, and solar panels require two. As it turned out, 15-ft was the exact length I needed, and it works fine. December 10, 2013
Rated 4.0 out of 5.0 by Looks like a good cable have not used it yet but will be using it starting in a week or two. February 25, 2014
