For photovoltaic applications, outdoor materials should be based on ultraviolet rays, ozone, drastic temperature changes and chemical erosion. Using low-grade materials under this environmental stress will cause the cable sheath to be fragile and even decompose the cable insulation layer. These conditions will directly increase the loss of cable system, and at the same time, the risk of cable short circuit will also increase. In the medium and long term, the possibility of fire or personal injury is higher.
These cables and components not only have the best weather resistance, ultraviolet and ozone corrosion resistance, but also can withstand a wider range of temperature changes.
Moreover, photovoltaic cables generally use double-layer insulating rubber sheath!
Experiments have been done. Ordinary AC cables are placed outdoors, and the insulation sheath of AC cables is very aging and discolored.
So the most important thing for you is whether the cross-sectional area of photovoltaic cable meets the requirements of your AC side current; You can change it if you can.
