Geosiry Twin Wire Solar Panel Extension Cable - 30Ft 10AWG(6mm²) Solar Extension Cable with Female and Male Connector, Solar Panel Wire Adapter for Home, Shop and RV Solar Panels (10AWG 30FT)

They have and extra layer of protection with a strong material around the outside of the wires holding them together and protecting them. They install and come apart quickly with no tools needed. 10awg large diameter copper wires. Hard to beat these, would like to see some longer lengths to try the panels in different locations. With the 30ft cables getting over the rated watts when in direct sun. 1238w with 3-400w panels.

I use this as extension cord to hook up the solar panel on my deck to the EvoFlow Delta 2 inside the house. It works well.

Exceptionally well-made, Exceeded my expectations!

Love this extension

Great quality and on time

They look to be well made with good insulation on the cables.

Good Quality.

We like the product and it’s working fine

One ground end, that was not put together correctly, caused some time to figure out and repair.

I bought the 30ft cable and worked as expected. Then, I need additional cables 40 or 50 ft in length but the seller does not offer various lengths.
