Victron Galvanic Galvanic Energy VDI | 16 Galvanic Isolator 2 | 4Boats

The Victron Energy VDI-16 is a passive galvanic isolator for 230 V shore power that uses two anti-parallel diodes to block electrolytic currents until a fault voltage appears.

• Model: VDI-16 from Victron Energy
• Diode pair in anti‑parallel; conduction threshold ≈ 1.4 V DC
• Designed for installation directly behind the boat's 230 V shore inlet
• Forward voltage exceeds typical metal-to-metal potential differences, preventing electrolytic current
• Allows conduction only on higher fault voltages so the residual-current device (RCD) can trip
• Passive, maintenance‑free component-no external power required
• Reduces risk of galvanic corrosion on marine AC systems
• Should be fitted by a qualified electrician for safe operation

Check compatibility with your vessel's shore-power system and consult a marine electrician for installation and testing.
