Do you sell an MC4 "unlatch tool"? The connections can be difficult if not impossible by hand.

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.

15 ft. Extension Cable is rated 4.3 out of 5 by 10.
Rated 5 out of 5 by from Only single cable Be advised, this is only a single conductor cable. It has male and female ends. No. 8 stranded wire. I only needed to go about 5 feet, so I cut it in half and it was perfect. If you need to go more than 7 ft, you will need to buy 2 of these cables. I was impressed as they are high quality outdoor cables.

Rated 5 out of 5 by from Exactly as indicated Useful for those installations that require more length than whatever comes with the solar panel. Good quality MC4 fittings, and the gauge of wire is, refreshingly, large enough.
Date published: 2016-08-23
Rated 5 out of 5 by from 15 ' extension cable Reading a review about extension cables is very helpful. I believe I'll purchase the proper connecters and upgrade the wire size. Will the MC4 connecters work with #4 wire ?

Rated 5 out of 5 by from worked great ,thank-u worked great ,thank-u
Date published: 2016-10-26
Rated 1 out of 5 by from 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

Rated 5 out of 5 by from 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.
Date published: 2014-07-10
Rated 4 out of 5 by from Part of a larger purchase. The description needs to be updated to indicate that you will need two of these. Otherwise very pleased.
Date published: 2014-07-01
Rated 4 out of 5 by from 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.
