Victron Solar Cable 5m 6mm² MC4 M/F Connectors | PV-ST01 SCA000500100

A pre-assembled 5-metre solar DC cable from Victron Energy, fitted with MC4-compatible male and female connectors (PV-ST01 type). It connects solar panels to combiner boxes, charge controllers or other DC wiring in a PV installation. The 6mm² cross-section suits higher-current panel strings where voltage drop and heat matter.

Key features of this solar panel cable

• Length, 5 metres, ready to install with no crimping or termination needed.
• Conductor size, 6mm² cross-section for higher-current PV string connections.
• Connectors, MC4-compatible PV-ST01 male and female, one at each end.
• Build, UV-resistant cable construction for outdoor DC solar use.
• Supplier, Victron Energy.

Product overview

Pre-terminated cables remove the risk of a poorly crimped connector on site. This one arrives with a PV-ST01 male connector at one end and a female connector at the other, so it works as a direct extension or interconnect for standard MC4-equipped panels and components.

The 6mm² conductor suits longer cable runs or higher panel current, cutting resistive losses compared with the more common 4mm² option. Over a 5-metre run, this helps keep voltage drop within acceptable limits and reduces heat build-up in the cable.

MC4 (PV-ST01) connectors are the industry standard for solar panel interconnection. They are rated for outdoor use and provide a secure locking connection, compatible with most solar panels and DC components on the market. Check connector brand compatibility before mixing types on the same string.

Applications

• Extending or interconnecting solar panel strings in residential and commercial PV systems.
• Connecting panels to string combiner boxes or DC isolators.
• Off-grid systems where panels feed directly into a charge controller or inverter-charger.
• Replacement or extra cabling for existing MC4-equipped PV arrays.
• Marine and mobile solar installations using standard MC4-compatible panels.

What's in the box

• 1 x Victron solar cable, 5m, 6mm², with MC4-compatible PV-ST01 male connector at one end and female connector at the other.

Installation notes

DC solar wiring should be carried out by a qualified electrician or MCS-accredited installer. Check cable polarity before making any connection, and confirm the PV-ST01 connectors are compatible with the connector brand used elsewhere in the string. Mixing connector brands without checking cross-compatibility can create a fire or arc-fault risk. On grid-connected systems, all DC wiring must comply with current UK wiring regulations and any applicable G98 or G99 requirements.
