Solar Cable Applications
4mm twin core solar cables are ideal for various applications within solar energy systems:
-
Cable Runs Between Solar Modules: These cables connect individual solar panels together in strings, carrying current from the panels to the inverter. The twin core design allows for carrying both positive and negative DC current within the same cable.
-
Extension Cable Between String Inverters: They can be used to extend the reach from the molded strings to the central DC/AC inverter, accommodating for larger installations.
Solar Cable Standard
4mm twin core solar cable is a versatile solution for transferring electrical energy in photovoltaic (PV) systems, particularly well-suited for cabling between solar modules, and as extension cables between molded strings and the DC/AC inverter in photovoltaic plants, solar parks, gable roof systems, and flat roof PV systems.
Here are some of the key features of 4mm twin core solar cables:
-
Efficient Power Transfer and Durability: 4mm twin core solar cables are typically constructed with tinned copper conductors for high conductivity and efficient energy transmission. They are coated with a UV-resistant jacket to protect them from sun damage and a moisture-resistant jacket to shield them from water and other liquids, ensuring long-lasting performance in outdoor environments. The twin core design provides two insulated conductors within the same jacket, which is useful for carrying positive and negative DC current within the same cable.
-
Easy Installation and Customization: 4mm solar cables are designed for easy installation. They are flexible and can be quickly connected to solar panels and other components of your solar energy system. Additionally, they are available in a variety of lengths and colors to meet the specific needs of different solar panel system designs.

Rated Voltage
The rated voltage of a solar cable refers to the maximum voltage it can safely handle. The higher the voltage rating, the thicker the cable insulation will need to be.
Conductor
The conductor of a solar cable is the part that carries electricity. Solar cables typically use tinned copper conductors because tinning helps prevent corrosion.
Jacket
The jacket of a solar cable is the outer layer that protects the conductor from moisture, sunlight, and abrasion. Solar cable jackets are typically made from cross-linked polyethylene (XLPE)
Durability
Solar cables are designed to withstand harsh outdoor environments, including exposure to sunlight, rain, snow, and extreme temperatures.
Temperature
Solar cables are rated for a certain temperature range. The maximum temperature rating of a solar cable is the highest temperature it can safely operate at. Common temperature ratings for solar cables include -40°C to +90°C.
