Solar cables

Solar cables of KBE

Solar cables connect the modules of a photovoltaic system to each other and to the inverter. They stay outdoors for decades, exposed to heat, frost, UV radiation and moisture. As a Berlin-based manufacturer we produce solar cables built for exactly these conditions, from the standard cable to EN 50618 through versions for large cross-sections to cables for floating installations.

KBE supplies installers, wholesalers, system builders and project developers, either by the metre on coils, pre-assembled with connectors, or as a project quantity for solar parks.

Our solar cables are triple certified according the European spec. EN 50618 (H1Z2Z2-K), international standard IEC 62930 (IEC 131) and 2Pfg 1169 /10.2019 (PV 1500-K). This guarantees excellent technical properties, safety and a long lifetime of min. 25 years.

In general the requirements for solar cables have changed dramatically in recent years. Inappropriate components can cause rapid failures leading to high complaint- and replacement costs, even after a short operation life of a PV power plant.

Which cross-section for which system?

The cross-section determines how much power is lost on the way from the module to the inverter. The longer the run and the higher the current, the larger it should be. For long cable routes and large installations the KBE Solar DB is also available in large cross-sections from 16 to 35 mm², see the product overview above.

For conversion between metric sizes and American Wire Gauge, use our AWG table. How installation method and ambient temperature affect the result is explained in our guide on the current carrying capacity of solar cables.

By the metre, pre-assembled or as a project quantity

Solar cables do not have to leave our works as plain metre goods. On request we cut to length, crimp the connectors, label and overmould the joint in the factory. That saves assembly time on site and makes the quality of every connection reproducible. Details are on the page for pre-assembled solar cables.

For ground-mounted systems and solar parks we deliver bulk quantities on drums at project conditions. Contacts and process are described under solar cables for EPCs and solar park developers. The available packaging units are listed under packaging.

Frequently asked questions about solar cables

What does H1Z2Z2-K stand for?

H1Z2Z2-K is the type designation under EN 50618. It describes a single-core cable with cross-linked, halogen-free insulation and a flexible copper conductor, rated for photovoltaic applications at 1,500 V DC.

Can solar cables be laid underground?

Solar cables to EN 50618 are designed for outdoor use and are resistant to UV, weather and water. Laying them underground places additional demands on mechanical protection and burial depth. Our guide on the installation of solar cables covers the key points.

Which cable is suitable for floating PV systems?

Floating PV places higher demands on water resistance and insulation resistance, because the cable sits in or on the water permanently. For this we offer KBE Solar Floating to 2PfG 2750/09.20 as a dedicated version.

Which colours and packaging units are available?

As standard we supply black, red and blue on coils of 500 m and 1,000 m. Other lengths and drums are available for projects.

What does the Dca fire classification mean?

Dca is a reaction-to-fire class under the EU Construction Products Regulation. It documents how a cable behaves in a fire and is required for many building projects. Our solar cables are classified accordingly.
