A vital safeguard against corrosive damage for your boat's metals.

Product Details

The Victron Energy galvanic isolator serves as a crucial component for preventing electrolytic corrosion on your boat. It effectively blocks low voltage DC currents entering your vessel via the shore power earth wire, which can lead to corrosion on underwater metals such as the hull, propeller, and shaft. Internally, it consists of two diodes arranged in an anti-parallel configuration, permitting current flow only above a threshold voltage of approximately 1.4 Vdc. This isolator should be installed directly behind your boat’s 230V connection. The forward voltage of the galvanic isolator exceeds the potential difference between different metals, ensuring that electrolytic currents are blocked. However, in the event of a higher fault voltage within the AC circuit, the diodes will conduct and allow current through, enabling the residual current device to safely interrupt the circuit.
