DESCRIPTION

Victron 4500W Isolation Transformer: Shore Power Safety and Galvanic Corrosion Protection

Reliable Electrical Isolation for Marine Shore Power Systems

The Victron Energy 4500W Isolation Transformer provides complete electrical separation between shore power and a vessel's onboard AC system. By removing electrical continuity between the shore-side supply and the vessel, it helps prevent galvanic corrosion while supporting the correct operation of essential safety equipment such as GFCIs and circuit breakers.

Designed for use with 115V or 230V AC input, the transformer can be configured during installation to provide either 120V or 240V AC output. This allows it to provide electrical isolation or voltage conversion for vessels operating with different shore power and onboard voltage systems.

Why Galvanic Isolation Matters

Connecting a vessel directly to shore power can create an electrical path between the shore earth and underwater metal components such as propellers, shafts and through-hull fittings. This can accelerate galvanic corrosion, rapidly deplete sacrificial anodes and cause premature damage to valuable underwater equipment.

The Victron Isolation Transformer prevents this by transferring power magnetically between separate primary and secondary windings. Shore power is connected to the primary side, while the vessel's electrical system is supplied from the secondary side, electrically isolating the vessel from the shore earth.

This protection is important for fibreglass vessels as well as aluminium and steel hulls, as galvanic corrosion can occur whenever electrically connected metal components are exposed to water.

Flexible 115V and 230V Configuration

The transformer can be configured for different input and output voltages using the supplied jumper wires. The required voltage configuration must be selected during installation before power is applied.

  • 115V to 120V for isolation within a nominal 115V system
  • 230V to 240V for isolation within a nominal 230V system
  • 115V to 240V for stepping up a 115V shore supply
  • 230V to 120V for stepping down a 230V shore supply

The transformer supports both 50Hz and 60Hz AC systems. It does not convert frequency, so the output frequency remains the same as the input frequency.

5% Voltage Boost

The transformer's 1:1.05 winding ratio increases the output voltage by approximately 5%. This helps compensate for voltage drops commonly experienced across long shore power cables and marina electrical infrastructure. A 115V input provides approximately 120V output, while a 230V input provides approximately 240V output.

Key Features

  • 4500W power rating with output current ratings of 38A at 115V and 19A at 230V
  • Galvanic isolation between shore power and the vessel's onboard electrical system
  • Configurable 115V or 230V input for different shore power supplies
  • Configurable 120V or 240V output for isolation or voltage conversion
  • Soft-start technology to reduce transformer inrush current and help prevent upstream circuit breakers from tripping
  • 1:1.05 transformer ratio to compensate for common shore power voltage drops
  • Toroidal transformer design for reduced weight and low noise
  • Temperature-controlled fan cooling for reliable thermal management
  • Overtemperature protection that switches the transformer off if overheating occurs
  • Aluminium enclosure finished in Victron blue RAL 5012
  • IP21 protection rating
  • EN 60076 safety compliance

Soft Start and Temperature Protection

High-power transformers can draw significant inrush current when first connected to shore power. The integrated soft-start system limits this initial current, helping prevent the upstream shore-side circuit breaker from tripping when the transformer is switched on.

The transformer is also equipped with temperature-controlled fan cooling. Fan speed increases as the internal temperature rises, while built-in overtemperature protection switches the transformer off if unsafe operating temperatures are detected.

Correct Operation of Onboard Safety Devices

A GFCI must be installed on the AC output of the isolation transformer. For correct GFCI operation, the AC output neutral must be connected to the AC output earth and the vessel's grounding system using the supplied neutral-to-earth jumper.

When the vessel is out of the water for maintenance or winter storage, the vessel earth conductor must be connected directly to the shore power earth conductor. The transformer includes a dedicated connection and supplied jumper wire for this purpose.

Durable and Installation-Friendly Design

The transformer is housed in a durable aluminium enclosure with an IP21 protection rating. Cable glands provide secure entry points for the AC input and output cables, while the supplied hanging bracket and mounting hardware support installation inside the vessel.

The unit measures 362mm high x 258mm wide x 221mm deep and weighs approximately 22.22kg. At least 100mm of clear space should be maintained around the transformer for ventilation, and the cooling fan openings must remain unobstructed.

Professional Installation Required

The Victron 4500W Isolation Transformer is a Safety Class I electrical product and must be installed by a suitably qualified person. Input and output voltage configurations, cable sizes, protective earthing, GFCI protection and circuit breakers must comply with the installation manual and applicable local electrical regulations.

Protect Your Vessel and Onboard Electrical System

Suitable for cruising yachts, motorboats and commercial marine installations, the Victron 4500W Isolation Transformer combines galvanic isolation, voltage conversion and electrical safety in one robust unit. Its configurable voltage options make it especially useful for vessels operating across different shore power systems.

Order the Victron 115/230V 4500W Isolation Transformer today for dependable shore power protection and flexible onboard voltage configuration.
