Description
xVictron Energy Galvanic Isolator VDI-16A
The Victron Energy VDI-16A is a galvanic isolator designed to protect boat hulls and shore power wiring from galvanic corrosion. It is rated at 16A continuous and fits into the shore power earth conductor to block low-voltage DC galvanic currents while maintaining full AC earth continuity for safety. It is suited to marina berths, canal boats, and any vessel connected to shore power.
Key Features
- 16A continuous current rating, suitable for standard single-phase shore power connections.
- Blocks DC galvanic currents flowing through the shore earth conductor without interrupting AC earth protection.
- Diode-based design provides a blocking voltage threshold that stops corrosive galvanic currents at source.
- Compact and lightweight at 1.15 kg, allowing straightforward installation in confined bilge or panel spaces.
- Manufactured by Victron Energy, with consistent build quality and compatibility with Victron shore power systems.
Product Overview
Galvanic corrosion occurs when two dissimilar metals are connected through an electrolyte (seawater or canal water) and a conductive path such as the shore power earth cable. Small DC currents flow continuously through this path, gradually dissolving metal fittings, propellers, anodes and hull fittings. The VDI-16A interrupts this DC path by placing a pair of blocking diodes in series with the earth conductor. The diodes present a forward voltage drop that is high enough to stop galvanic currents (typically below 1V) but low enough that the earth conductor remains fully functional for AC fault protection.
The 16A rating matches the capacity of a standard 16A shore power supply, which is the most common connection found at UK and European marina pontoons. The unit is installed in-line on the earth conductor of the shore power cable, inside the vessel. Because it does not interrupt the protective earth under fault conditions, it complies with the principle of maintaining earth continuity required by marine electrical standards. Installers should verify compliance with the specific standard applicable to the vessel type and flag state.

Installation Notes
The VDI-16A must be installed by a qualified marine electrician familiar with the relevant marine electrical standards (such as BS EN ISO 13297 for European recreational craft). It is wired in-line on the earth conductor of the shore power inlet, inside the vessel. Incorrect installation, particularly any wiring that bypasses or interrupts the protective earth under fault conditions, creates a serious shock hazard. Do not install this unit without confirming the final installation meets the applicable standard for your vessel type and flag state.
