These currents can damage underwater metals such as the hull and propeller. The isolator features two anti-parallel diodes internally, which allow current to flow only above a threshold voltage of approximately 1.4 Vdc. Installed directly behind your boat's 230V connection, it prevents electrolytic current under normal conditions. In the event of a higher error voltage in the AC circuit, the diodes conduct, allowing the residual-current device to trip and break the circuit. This passive, maintenance-free component is crucial for reducing the risk of galvanic corrosion on marine AC systems. It is recommended that installation be carried out by a qualified electrician.
This guide is for boat owners who want to protect their vessel from galvanic corrosion. The Victron Energy Galvanic Isolator - 16A is designed to prevent electrolytic corrosion by blocking low voltage DC currents that can enter through the shore power earth wire. A key benefit is the reduction of the risk of damage to underwater metals, leading to significant savings on repairs. However, it's important to note that installation should be carried out by a qualified electrician.

FAQs
What is galvanic corrosion?
Galvanic corrosion is the electrochemical process where one metal corrodes preferentially when in electrical contact with a dissimilar metal in the presence of an electrolyte, such as saltwater. This can damage underwater metals on boats.
How does the galvanic isolator work?
The isolator blocks low-voltage DC currents that cause corrosion while allowing AC current to pass through to power your boat's electrical systems. It uses two anti-parallel diodes to achieve this.
Who should install the galvanic isolator?
The galvanic isolator should be installed by a qualified marine electrician.
Is the galvanic isolator maintenance-free?
Yes, the Victron Energy Galvanic Isolator is a passive, maintenance-free component.
What is the benefit of using a galvanic isolator?
The primary benefit is reducing the risk of galvanic corrosion, which can extend the life of underwater metal components like the hull and propeller, and save on repair costs.
What should I do if my RCD trips after installing the isolator?
If the RCD trips frequently, there might be a ground fault in your system. Consult a qualified electrician to inspect the electrical system and find the fault.
Where is the isolator installed?
The isolator is installed directly behind the boat's 230V AC shore power connection.
What are the common signs of galvanic corrosion?
Common signs include pitting, rust, and degradation of underwater metal components such as the hull, propeller, and shafts.
Troubleshooting
Device is not working after installation.
Check all connections to ensure they are secure and correctly wired. Consult the wiring diagram and have an electrician verify the installation.
RCD trips frequently.
This could indicate a fault in the AC circuit. Check for any ground faults in the system. Consult a qualified electrician to identify the source of the problem.
