Isolation Transformer - 2000W - 115/230 VAC
Safety and prevention of galvanic corrosion The Isolation Transformer eliminates any electrical continuity between AC shore power and the boat. It is essential for safety and eliminates the need for galvanic isolators and polarity alarms.
Safety is taken for granted in case of a normal on-shore installation. A fuse will blow or a GFCI (Ground Fault Current Interrupter) will trip in case of a short circuit or current leakage to ground. Connecting the ground wire of the shore-side supply to the metal parts of the boat will result in galvanic corrosion (see below). Bringing only the live and neutral wire on board results in an unsafe situation because GFCIs will not work nor will a fuse blow in case of a short circuit to a metal part on the boat.
Galvanic corrosion occurs when two dissimilar metals in electrical contact are simultaneously exposed to an electrically conducting fluid. Seawater and, to a lesser extent, fresh water are such fluids. In general, the more active alloy of the couple corrodes preferentially while the less active (more noble) material is cathodically protected. The rate of galvanic corrosion is a function of several variables including area ratios, conductivity of the fluid, temperature, nature of the materials, etc.
It is a misunderstanding that galvanic corrosion occurs only in metal and aluminium hulls. In fact it can occur on any boat as soon as a metallic part (the shaft and propeller) is in contact with water. Galvanic corrosion will quickly dissolve your sacrificial anodes, and attack the shaft, propeller and other metal parts in contact with water as soon as the boat is connected to the shore-side supply. It might therefore be tempting not to connect the ground conductor: this is however extremely dangerous because GFCIs will not work nor will a fuse blow in case of a short circuit to a metal part on the boat.
The best solution to avoid galvanic corrosion and at the same time prevent any unsafe situation is to install an Isolation Transformer to connect to the shore-side supply.
The Isolation Transformer eliminates any electrical continuity between shore power and the boat. The shore power is fed to the primary side of the transformer and the ship is connected to the secondary. The Isolation Transformer completely isolates the boat from the shore ground. By connecting all metal parts to the neutral output on the secondary side of the transformer, a GFCI will trip or a fuse will blow in case of a short circuit.
Soft startis a standard feature of a Victron Energy isolation transformer. It will prevent the shore power fuse from blowing due to the inrush current of the transformer, which would otherwise occur

The Victron Energy ITR040202041 Isolation Transformer provides a reliable 2000W power solution designed specifically for marine applications. It ensures safety and prevents galvanic corrosion by electrically isolating your boat from shore power sources, thereby eliminating electrical continuity between the two. This isolation is crucial for maintaining the integrity of your vessel's metal components and safeguarding against corrosion caused by seawater or freshwater exposure. The transformer's primary side connects to the shore power, while the secondary side supplies your boat, effectively disconnecting the electrical grounds and preventing galvanic corrosion without compromising electrical safety.
One of the key features of this transformer is its soft start capability, which minimizes inrush current during startup, thereby protecting your shore power fuse or GFCI from tripping due to sudden power surges. The transformer’s design incorporates safety features that allow all metal parts to be connected to the neutral output on the secondary side, ensuring that any short circuit or leakage will trip a GFCI or blow a fuse, alerting you to potential issues. This setup maintains a safe environment onboard while preventing costly damage to metal components like the shaft and propeller, which are vulnerable to galvanic corrosion when exposed to water.
The Victron Energy isolation transformer is engineered for durability and ease of installation, offering a robust solution for boat owners seeking to enhance safety and system longevity. Its compact size and straightforward wiring make it suitable for a variety of marine configurations. Additionally, Victron’s commitment to quality is backed by a comprehensive warranty, and detailed installation and operation instructions are available via the provided manual link. Proper use of this transformer helps prevent corrosion, ensures compliance with safety standards, and promotes the longevity of your vessel’s metallic parts, making it an essential component for any boat connected to shore power.
