The best solution to avoid galvanic corrosion and at the same time prevent any unsafe situation arising from electrical continuity between AC shore power and the boat is to install a Victron Isolation Transformer to connect to the shore-side supply.

The Isolation Transformer eliminates any electrical continuity between shore power and the boat. The shore power is fed to the primary side of the transformer and the ship is connected to the secondary. The Isolation Transformer completely isolates the boat from the shore ground. By connecting all metal parts to the neutral output on the secondary side of the transformer, a GFCI will trip or a fuse will blow in case of a short circuit.

Soft start is a standard feature of a Victron Energy isolation transformer. It will prevent the shore power fuse or breaker from blowing due to the inrush current of the transformer, which would otherwise occur. It is also recommended, for optimal safety, to connect the secondary neutral of the transformer to ground when the boat is out of the water.

This model will automatically switch to 115V or 230V supply, depending on input voltage; output voltage must be configured via jumper to either 115V or 230V output.

Supply 88V – 130V: switches to 115V supply

Supply 185V – 250V: switches to 230V supply range. Note: The AC input voltage is raised by 1:1.05 ratio at the AC output.
