The Victron Isolation Transformer 3600W 115/230V is a galvanically isolating transformer built for shore power connections on boats, yachts and shore-tied installations. It breaks the direct earth link between shore supply and vessel, removing the risk of stray current corrosion and electric shock that a hard-wired earth bond can cause.

Key features

• Power rating, 3600W continuous, enough for battery charging, air conditioning and galley loads at once.
• Dual voltage, 115V and 230V on both input and output, so one unit covers UK, European and North American shore supplies.
• Galvanic isolation, magnetic coupling replaces a direct electrical connection, stopping DC galvanic current flowing through the earth conductor.
• Toroidal core, keeps flux leakage low and the enclosure compact for its power class.
• Weight, 21.73 kg, reflecting the core needed for a 3600W toroidal design.

Product overview

Shore power at a marina normally ties a vessel's earth to every other boat and metal structure sharing that supply. Left unbroken, this forms a galvanic cell that accelerates corrosion of props, stern gear, anodes and hull fittings. This transformer removes that path by transferring AC power magnetically rather than through a direct wire, while the output is re-earthed locally on the vessel side so RCD and earth fault protection on onboard circuits still works as normal.

Applications

• Shore power on sailing yachts, motor cruisers and live-aboard vessels.
• Marina berths where several vessels share a common earth.
• Shore-tied commercial vessels and workboats needing AC isolation.
• Installations stepping between 115V and 230V shore supplies.

Installation notes

Fitting must be carried out by a qualified marine electrician, wired to BS EN ISO 13297 for recreational craft in the UK and EU. At 21.73 kg the unit needs a structural, vibration-damped mounting surface with ventilation clearance, and the shore supply must be isolated at the pedestal before any connections are made.
