Cable review

I bought a series of different cable sizes and multiple lengths. They are great, well made and will make my new solar system perform as it should. They were shipped quickly and arrived in a few days. Great service, great product and I will be doing more business in the near future. 5 stars Windy Nation, thank you .

My Latest WN Cables

Well my Windy Nation cables finally arrived after some shipper inconveniences, well its Christmas so we fully understand their delay. Cables are outstanding but after all they are Windy Nation and we have come to expect and be delighted by the consistent high quality of their materials and craftsmanship. Thanks to all of you at Windy Nation that crafted, administered and processed the product that has been delivered to me! (pic shows latest two cables not yet connected to the busbar where my other Windy Nation cables are all connected)

6 Gauge (AWG) Black and Red

If wire can be beautiful, this is a portrait. Already installed because it was delivered early, I wasn't expecting it until after the weekend. Get some ... Mark
