Frequently Asked Questions about 4 mm² Solar Cable

Is this cable suitable for outdoor installations?

Yes, this cable has UV protection and is made with materials designed to withstand direct exposure to sunlight, rain, humidity, and sudden temperature changes without cracking or losing its insulating properties.

What advantage does H1Z2Z2-K certification offer compared to other conventional cables?

The H1Z2Z2-K certification is the specific European standard for solar power cables. It guarantees a superior level of safety, greater durability against thermal and environmental stress, and optimal fire performance thanks to its halogen-free and low-smoke emission properties.

Can this cable be used with both direct and alternating current?

It is primarily approved for direct current (DC) photovoltaic installations between the panels and the inverter, although it is also suitable for alternating current (AC) systems within the voltage limits established in its technical specifications.

Is it flexible and easy to install in small spaces?

Yes, its construction with flexible copper facilitates the crimping of terminals and passage through corrugated tubes, cable trays or channels, significantly speeding up the installation time in any type of photovoltaic structure.
