xVictron Energy Isolation Transformer 3600W 115/230V
The Victron Energy Isolation Transformer 3600W is a galvanically isolating transformer designed for shore power connections on boats, yachts and shore-tied installations. It eliminates the risk of stray current corrosion and electric shock hazard caused by a direct earth connection between shore power and the vessel or installation. Suitable for both 115V and 230V systems, it covers the full range of marina shore supplies encountered in the UK, Europe and North America.
Key Features
- 3600W continuous power rating handles substantial onboard AC loads without derating.
- Dual voltage input and output (115V and 230V) makes it compatible with shore power supplies across different regions.
- Galvanic isolation breaks the earth continuity between shore supply and the vessel or installation, preventing stray current corrosion on underwater metalwork.
- Toroidal transformer core construction reduces magnetic flux leakage and keeps the unit compact relative to its power rating.
- Robust metal enclosure rated for the demanding environments found in marine and dockside installations.
- SKU: ITR040362042 | GTIN: 8719076066118
- Weight: 21.73 kg, reflecting the substantial core required for a 3600W toroidal design.
Product Overview
When a vessel or shore-tied installation is connected to marina or dockside shore power, a direct earth bond between the shore supply and the hull creates a galvanic cell with other vessels and metal structures in the water. Over time this causes accelerating corrosion of propellers, stern gear, anodes and hull fittings. An isolation transformer breaks this path entirely by providing AC power transfer through magnetic coupling rather than a direct electrical connection, so no DC galvanic current can flow through the earth conductor.
The 3600W rating is sufficient to supply a typical live-aboard or charter vessel with shore power for battery charging, air conditioning, galley equipment and general AC loads simultaneously. The 115/230V dual voltage capability means the same unit can be installed once and used at marinas in the UK, continental Europe and North America without modification. The transformer output is re-earthed locally on the vessel side, maintaining full RCD and earth fault protection on the onboard circuits.
At 21.73 kg, this is a substantial unit and installation location should be planned carefully to keep cable runs short and to mount the transformer on a solid, vibration-damped surface. The toroidal core design keeps the footprint manageable for the power class, but adequate ventilation must be provided around the enclosure.

Applications
- Shore power connections on sailing yachts, motor cruisers and live-aboard vessels to prevent galvanic corrosion of underwater metalwork.
- Marina berth installations where multiple vessels share a common earth and galvanic isolation is required between them.
- Shore-tied commercial vessels and workboats requiring compliant AC power isolation.
- Any installation where a floating earth on the load side is required for safety or equipment protection reasons.
- Dual-voltage installations where the shore supply voltage differs from the onboard system voltage (115V to 230V step-up or step-down).
What Is Included

Installation Notes
This transformer must be installed by a qualified marine electrician or a competent person with appropriate experience in AC shore power systems. All wiring must comply with the relevant standard for the installation type (BS EN ISO 13297 for recreational craft in the UK and EU). The transformer is heavy at 21.73 kg and must be securely mounted to a structural surface capable of bearing the load, with adequate ventilation clearance around the enclosure. The vessel-side earth must be re-established from the transformer output neutral or earth terminal in accordance with the wiring standard. Do not attempt installation without isolating the shore supply at the shore power pedestal before making any connections.
