Solar Cable

solar cable system for solar panel

Solar cable is an electron beam cross-link cable rated at 120°C to withstand harsh weather conditions and mechanical shock in the equipment to which it belongs.
Solar technology will be one of the green energy technologies of the future, and solar energy or photovoltaic (PV) is becoming more and more widely used internationally. In addition to the rapid development of government-supported PV power plants, ZMS Cable is expanding its solarflex portable extension solar cable system production line with plans to put into production solar cables and assemblies that will be sold worldwide. ZMS produces high-quality 4 mm, and 6 mm solar DC cables. You can always contact us for the latest solar cable prices and more discounts.

Selection of Photovoltaic Solar Cables

The cables used in the low-voltage DC transmission part of the solar photovoltaic power system have different requirements for the connection of different components because of the different use environments and technical requirements.
The overall factors to be considered are cable insulation performance, heat and flame resistance, aging performance, and wire diameter specifications.

Specific Requirements are as Follows

1. Solar modules and components between the connection cable, generally use the connection cable attached to the module junction box directly connected, the length is not enough to use a special extension cable.
Depending on the size of the module power, this type of connection cable has a cross-sectional area of 2.5m ㎡, 4.0m ㎡, 6.0m ㎡ , and other three specifications.

This type of connection cable uses a double layer of insulation sheath, which has superior resistance to UV, water, ozone, acid, and salt erosion, superior all-weather capability, and wear resistance.

2. The connection cable between the battery and the inverter requires the use of UL-tested multi-strand flexible wire, connected as close as possible. Choosing short and thick cables can reduce the loss of the system, and improve efficiency and reliability.

3. The connection cable between the battery array and controller or DC junction box is also required to use UL-tested multi-stranded flexible wire with the cross-sectional area according to the maximum output current of the array.

The DC cable cross-sectional area of the named parts is determined based on the following principles.
Solar cell modules and components between the connection cable, battery and battery connection cable, AC load connection cable, generally selected cable rated current for each cable in the maximum continuous operating current of 1.25 times.
Connection cables between solar cell arrays and arrays, connection cables between batteries (groups), and inverters are generally selected with a cable current rating of 1.5 times the maximum continuous operating current in each cable.

The above is the recommendation of ZMS cable team personnel. If there is anything else you do not understand, you can always contact the ZMS team. We will be happy to serve you.
