Questions about this product

Which AWG should I pick for my solar setup?
It depends on your current and run length. Heavier wire like 10 AWG (6mm2) handles more amps with less voltage drop, while 14 AWG (2.5mm2) suits lower-current runs. Match the gauge to your panel output and how far the cable travels to the controller.
Will these connectors plug into my existing MC4 panels?
Yes. The pre-assembled connectors are MC4-compatible, so they mate with standard MC4 panel leads, charge controllers, and inverters. Just push them together until they click for a weatherproof seal.
Can I leave this cable outdoors year-round?
Yes, it's built for permanent outdoor use. The double-insulated jacket resists UV, ozone, and temperatures from -40C to +90C. The cable is rated to 1000V DC minimum, so it handles typical residential and off-grid solar arrays.
