How to choose the right cable to connect the solar triplex junction box
1.Current capacity: Determine the required current capacity to ensure that the selected cable can carry the required current. This depends on the power of the solar panels and the design requirements of the system. In general, the specifications of the solar system and the recommendations provided by the manufacturer can be referred to select the appropriate cable.
2.Cable size: According to the current capacity and cable length, select the appropriate cable size. Larger currents require a larger conductor cross-sectional area to reduce resistance and power losses. Refer to a cable size chart or consult a professional to determine the appropriate cable size.
3.Cable type: Choose the type of cable that meets the requirements of the solar system. Common types of solar cable include direct current (DC) solar cable and alternating current (AC) solar cable. Dc solar cables are used to connect the solar panels to the triplex junction box, while AC solar cables are used to connect the triplex junction box to the inverter.
4.Weather resistance and durability: solar cables should have good weather resistance and durability, and be able to resist the influence of harsh environmental conditions such as ultraviolet light, high temperature and humidity. Choose cables with UV and corrosion protection properties to ensure their long-term stable performance.
5.Compliance with standards and certification: Ensure that the selected cables meet relevant standards and certification requirements, such as International Electrotechnical Commission (IEC) standards, solar industry standards, etc. This can ensure the quality and safety performance of the cable.
When selecting a cable, it is recommended to refer to the design specifications of the solar system, recommendations provided by the manufacturer and relevant standards to ensure that the selected cable meets the system requirements and can provide reliable power transmission.
