Application
Photovoltaic solar h1z2z2-k cable is an indispensable key component in the photovoltaic system. It mainly connects solar panels with inverters, junction boxes or control equipment, efficiently transmits DC power, and ensures the stable operation of the entire system.
4mm solar pv cable is particularly suitable for medium-power rooftop photovoltaic systems, home solar systems, and small commercial solar installations due to its excellent conductivity and moderate size. It uses cross-linked polyolefin (XLPE) insulation and sheath, with excellent high temperature resistance, UV resistance, ozone resistance, moisture resistance and mechanical strength, and can operate stably for a long time even in extreme outdoor environments. In addition, the cable also has flame retardancy and low smoke emission characteristics, which improves the overall safety of the system and is particularly suitable for installation environments that require a high level of safety. Its flexible structure also facilitates on-site wiring and maintenance.
Feature
4mm solar pv cable refers to a specific specification of photovoltaic cable, where 4mm² / 6mm2 refers to the cross-sectional area of the cable conductor being 4 square millimeters / 6 square millimeters. This type of cable is commonly used in photovoltaic systems to connect photovoltaic modules and inverters or to connect the DC and AC sides of photovoltaic systems. The design of photovoltaic cables takes into account weather resistance, UV resistance, and good insulation performance, making them suitable for outdoor use.
Certification
Solar PV cable 4mm has successfully passed TUV and UL certification. The TUV certification number is No. B 126326 0001 Rev.00. The cable complies with relevant standards such as EN 50618 and can operate stably and long-term in harsh environments.
At the same time, the UL certification number is UL-US-2561141-0. Photovoltaic cable also meets the strict requirements of the North American market for electrical performance, fire retardancy, and weather resistance, and is suitable for a variety of solar power generation projects, whether residential, commercial, or industrial applications.
All certification information can be directly verified on the official websites of TUV and UL, which are transparent and reliable. Choosing us means choosing quality-assured and internationally recognized PV cable suppliers.

FAQ
Q: Can I use 4mm cable for solar panels?
Q: How many amps can a 4mm solar cable handle?
Q: What is the difference between 4mm and 6mm solar cable?
Current Carrying Capacity:
4mm² Cable: Typically handles around 25 to 30 amps.
6mm² Cable: Generally supports around 35 to 45 amps.
Voltage Drop:
4mm² Cable: Higher voltage drop over long distances compared to a 6mm² cable. This can lead to inefficiencies in power transmission.
6mm² Cable: Lower voltage drop, which means better efficiency in
Physical Size and Flexibility:
4mm² Cable: Thinner and more flexible, making it easier to handle and install, especially in tight spaces or complex configurations.
6mm² Cable: Thicker and less flexible, which might make it a bit more challenging to work with, but it offers better performance in terms of current capacity and voltage drop.
Q: Can I use 6mm solar pv cable instead of 4mm?
