Important Safety Information

This cable is for DC use only and must never be disconnected under load. Isolate the DC side of the PV system fully before connecting or disconnecting any cable runs.

Good to Know

Also available as a 500m reel for larger installations.

What is the difference between H1Z2Z2-K cable and standard twin-and-earth cable?

H1Z2Z2-K is a single-core, double-insulated cable purpose-built for photovoltaic DC wiring, with UV, ozone and water resistance and a 25+ year outdoor service life — general building wiring cable is not rated for these conditions and should not be used for PV DC runs.

Is this cable suitable for both panel interconnection and main DC runs?

Yes, at 10mm² this cable is suitable for panel-to-panel wiring and longer DC main cable runs from the array to the inverter, where the larger cross-section helps minimise voltage drop over distance.

Which connectors work with this cable?

This cable is compatible with all brands of MC4-style connectors designed for 10mm² conductors — check your chosen connector's specification matches this cable's conductor size before crimping.

Can this cable be installed in wet or underground conditions?

The cable carries an AD8 water resistance rating to IEC 60364-5-51 and IEC 60529, making it suitable for wet, damp and humid installation environments; always follow local wiring regulations for any underground or submerged routing.

What length options are available?

This cable is available as a 100m reel or a 500m reel, both in black, allowing you to size your purchase to the scale of your installation.
