Victron Energy Galvanic Isolator VDI-16 A – Reliable protection against galvanic corrosion in solar and onboard systems
The Victron Energy Galvanic Isolator VDI-16 A is a compact galvanic separator designed for installation between shore power and the onboard system of motorhomes, boats, and off-grid solar installations. It interrupts harmful equalising currents and protects batteries and electrical components from galvanic corrosion.
Effectively prevents galvanic corrosion by interrupting equalising currents between shore power and onboard system
Rated current of 16 A – ideal for typical shore power connections of motorhomes and boats
Simple inline installation without additional wiring – mounts directly between shore power outlet and onboard system
Robust, compact housing for use in humid and demanding environments
The VDI-16 A from Victron Energy offers a straightforward and effective solution to prevent costly damage to batteries and electrical systems caused by corrosion. Unlike complex isolation relays, it operates purely passively and requires no external power supply or control – making it particularly maintenance-free and reliable in continuous operation.
Ideal for...
This galvanic isolator is the perfect choice for owners of motorhomes, caravans, boats and yachts who regularly connect their vehicle or vessel to shore power. It is also used in off-grid solar installations with battery storage and external power sources – wherever different earthing potentials meet and corrosion threatens.
How to use the Galvanic Isolator VDI-16 A
Mount the device in the supply line between the shore power outlet and your onboard system. Ensure correct orientation of the connections according to the instructions. The isolator requires no separate power supply and begins its protective function immediately. Regularly check the condition of the connection cables and housing.

The brand stands for reliability, durability and technical innovation in the field of energy autonomy.
A galvanic isolator prevents harmful equalising currents between two differently earthed electrical circuits, such as those that can occur between shore power and the onboard system of a motorhome or boat. This effectively prevents electrochemical corrosion of metal parts of the installation.
The VDI-16 A is installed between the shore power supply and the onboard system of a motorhome, caravan or boat. It protects batteries, chassis and other metal components from galvanic corrosion caused by differences in earthing potential.
The Victron Energy Galvanic Isolator VDI-16 A has a rated current of 16 amperes, a weight of approximately 1.16 kg and is classified as a battery monitor accessory. It is designed for 230 V shore power connections.
Yes, installation is relatively straightforward. The isolator is inserted into the supply line between the shore power outlet and the onboard system. No separate power supply is required. It is recommended that a qualified electrician carries out the installation.
Victron Energy provides a 24-month manufacturer warranty on the Galvanic Isolator VDI-16 A. It covers defects in materials and workmanship under normal use conditions.
