A pre-assembled 1 metre solar cable from Victron Energy, fitted with MC4-compatible male and female connectors of the PV-ST01 type. It gives installers a ready-to-use bridging or extension lead for solar panel wiring, with no crimping or extra parts needed.

Key features

• Length, 1 metre, suited to short panel-to-panel or panel-to-combiner runs.
• Conductor, 6mm² cross-section, sized for standard residential and commercial PV string currents.
• Connectors, MC4-compatible male and female (PV-ST01), pre-fitted and ready to connect.
• Configuration, one male end and one female end on a single cable, for direct in-line extension.
• Weight, 0.144kg, easy to route in tight spaces.

Product overview

The 6mm² conductor is the usual cross-section for residential and light commercial PV string wiring across the UK and EU. A larger conductor cuts resistive losses over the run, which matters most where panels are wired in series strings at higher open-circuit voltages. At 1 metre, this cable suits bridging small gaps between panels, wiring into junction boxes, or extending an existing run without adding unnecessary resistance.

PV-ST01 connectors are a widely used MC4-compatible standard, so this cable can be inserted straight into an existing PV circuit with no extra crimping or adapters. Victron offers other cable lengths and conductor sizes for longer runs.

Applications

• Extending or bridging PV panel wiring on rooftop solar installations.
• Connecting solar panels to string combiners or junction boxes.
• Short cable runs between panels and charge controllers in off-grid systems.
• Repairing or replacing damaged short-run PV cabling on existing installs.
• Mobile and marine solar setups using standard MC4-type connectors.

What's in the box

• 1x Victron solar cable, 1m, 6mm², with MC4-compatible male connector on one end and female connector on the other.

Installation notes

Mate and de-mate MC4 connectors only with the correct MC4 disconnect tool, to avoid damaging the connector housing. PV string wiring can carry high DC voltages, so all installation and wiring work should be done by a qualified electrician or MCS-accredited installer, in line with BS 7671 and the relevant IET wiring regulations. Never connect or disconnect MC4 connectors under load.
