i understood the extension cable was free with a order over 45 dollars.

Will the 15 foot extent ion cable come with my 100 watt solar panel ? I understood the extension cable was free on a order over 45 dollars.
Asked by: omegaman
The extension cable is not free. The delivery of the solar panel is of a 45 dollar or more purchase.

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

Asked by: solarnewbee
We do not stock these, they are widely available online under the term "MC4 Disconnect".

Do I need an extension cable for each panel, or do multiple panels somehow tie together with the 400watt off-grid system

Also, are the cables specific to Grape systems, or are they standard of the industry?
Asked by: robert
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 compatible, they are an industry standard.

Customer Reviews

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.

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 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.

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 5 out of 5 by from 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.
