WindyNation8 AWG 8 Gauge Pair 20 Feet Black + 20 Feet Red Solar Panel Extension Cable Wire Solar Connector (Variety of Lengths Available)

I built a solar farm in my backyard and I have dozens of these wires of different lengths from 6 feet to 60 feet. I have been using these for years and I only buy these because based on my testing, they have predictable loss based on the voltage and amps I am using for each setup. I have not needed to replace any of them.I highly recommend them.

For the price, my husband and I were very impressed with the quality of these wires. Much better than the expensive product being replaced. Highly recommend.

I got the pair of red/black 40 feet and they worked out great. Only issue I had was when I rolled them out the red was short by about 10 feet. Luckily I was able to make it work.

I have bought from this company before and they offer the best value. My order was processed quickly and shipped to me in Hawaii quickly. Never had a problem before and I buy with confidence.

I needed a long reach of about 150ft from my solar panels to my charge controller. I looked for the longest time coming up dry. I then looked for cable to make my own, and the cost was ridiculous. I then found these on Amazon and was so happy. I have bought two 30ft sets from WindyNation before, but never thought they had such long cable lengths for sale.So now for the review. I ran the cables and plugged them in to get an instant connection. The cables are weather resistant and I have ne fear of them being exposed to elements. I will run them through a conduit next summer. But for now, I have a safe and reliable 8AWG cable connection for a 150ft cable length. My panels are delivering their daily dose of free sunshine power. We keep our battery bank topped off and running thanks to these cables.We have three separate battery banks each with different batteries, and now that we know these cables are our solution, we are going to set up our other panels and get more of these cables for our other battery banks.The only thing I do not like is that they are a little stiff and the coiling causes issues. But once you get them laid out and get the coiling untangled, they work great. These are top quality copper cables with superb insulation for weather proof use. The MC4 connectors provide a tight and secure weather proof connection as well. I personally think that these are hard to beat for the price, and they are a terrific value. I give them 5 stars.

I had purchased a 30' set of these but found out I didn't need them that long.So I got the 15' set and I noticed an small increase in the amount of voltagemy Ecoflow generator was receiving. These cables are sturdy and will insulated.

It's pretty good.

I was using a standard gauge feed for my two 100W panels to the WindyNation P30L charge controller. I had only seen 4.x amps from a single panel to a surprisingly low 5.3 amps when I reconnected the second panel. I figured anything that would help would be OK.While I figured I’d see some improvements going to 8 gauge, I was pleasantly surprised (actually shocked) the following equally sunny day when the charge controller input was displaying 8.4 Amps.Couldn’t be happier.While these come with MC4 connectors on both ends, I cut one end off to insert into the P30L input connectors.I thought about giving only 4 stars? Because the wires are STIFF! The insulation is stiff plastic, but rugged, and the conductor strands are very coarse, not finely stranded copper. While going to 8ga was an improvement, more conductors at low voltage (12V) is even /more/ current potential (though a small percentage I know) than merely going to a larger wire. That disappoints me. If the Windy Nation “kit” had come with MC4 connectors that would fit 8ga (they only fit to 10ga) I’d have used the very fine-strand 8ga wire I bought for this (I could not locate 8ga MC4s to buy separately).Otherwise very happy with the product.I had no idea I’d gain so much efficiency in just 20 feet by going up a gauge. I’ve always way oversized wiring for marine and RV 12V systems but I’ve never had or taken the opportunity to do an A to B comparison before. (I used 2/0 for the 5’ cables that feed my 1200W pure sine inverter which is oversized, too, and their swaged copper terminals are waterproofed. All in the name of efficiency and longevity. Sometimes overkill is exactly what’s needed)Highly recommended.

This wire is a little stiff to work with but once installed I noticed a difference in charging times.

i used it to extend my solar pannel charging reach to the control panel
