    KBE Solar DB 4–10 mm² H1Z2Z2-K DC Solar Cable

    Exact reference · KBE Solar DB H1Z2Z2-K · 4 / 6 / 10 mm² family

    Single-core DC photovoltaic cable for designed string-to-inverter routes.

    Conductor sizes
    4, 6 or 10 mm² tinned E-Cu · Class 5

    The selected size updates its exact technical record; route sizing still requires calculation.

    DC voltage
    1,500 V DC design · 1,800 V maximum condition

    The full string, connector and protection architecture controls the usable limit.

    Resistance
    3.39 mΩ/m maximum

    Positive and negative route lengths both enter the voltage-drop calculation.

    Supply
    Red or black · metre, 500 m reel or 1,000 m reel

    Each colour and format remains a separate cart and quote line.

    Do not select this cable from cross-section or 1,500 V DC alone. Confirm current, complete positive-and-negative route length, voltage drop, ambient temperature, grouping, connector rating, protection and installation method.

    01 · Product role

    What this product does in the system.

    KBE Solar DB is the paired positive/negative DC wiring path between PV strings, DC isolation or protection, and inverter MPPT inputs. It carries power only; switching, isolation, overcurrent protection and conversion are separate functions.

    Relevant applications

    • PV string positive and negative conductors
    • String-to-combiner or DC protection routes
    • DC protection-to-inverter MPPT routes

    Why ReneWave may shortlist it

    • Selectable 4, 6 or 10 mm² tinned-copper Class 5 construction
    • H1Z2Z2-K to EN 50618 and IEC 62930
    • Red and black supplied separately by measured length or reel

    Built-in capabilities

    Four functions, read before the headline specifications.

    Dedicated PV DC path

    Single-core cable carries one polarity between designed PV system points.

    Red and black conductors are ordered independently.

    Three selectable conductor sizes

    Choose 4, 6 or 10 mm² Class 5 tinned copper for the reviewed route.

    Resistance, diameter, mass and manufacturer article update with the selection.

    Outdoor cable construction

    Cross-linked polyolefin jacket is UV, weather and ozone resistant and halogen-free.

    Direct burial remains subject to the complete route design.

    Measured or reel supply

    Choose linear metres, 500 m reel or 1,000 m reel in red or black.

    The quote confirms current availability.

    System position

    Only the red and black DC conductors are this product.

    The cable carries DC power. It does not isolate, switch, protect against overcurrent or convert power.

    Positive and negative conductors, cross-sections and supply formats are separate order lines.

    A PV string connects through separate red positive and black negative KBE DC conductors to DC isolation and protection, then to a compatible inverter MPPT input. No AC, battery or export path is shown.

    Read the technical explanation

    One certified cable family with three conductor sizes.

    Choose 4, 6 or 10 mm² from the KBE Solar DB H1Z2Z2-K family. The selected size updates the conductor construction, resistance, diameter, mass and manufacturer article. Red and black remain separate order lines. Cable sizing remains an engineering decision based on current, complete route length, voltage drop, ambient temperature, grouping, connector rating, protection and installation method.

    Supply format

    Choose a cut length in linear metres or a complete 500 m or 1,000 m reel. The selected colour does not include the opposite polarity. Availability and the exact delivered reel construction are confirmed in the written quote.
