Galvanic Isolators

Galvanic isolators are necessary to protect your boat from electrolysis. Defender Marine offers galvanic isolators from ProMariner, Newmar and Yandina.

What is a galvanic isolator?

In the simplest terms a galvanic isolator interrupts the flow of stray electricity in the water around your boat. The isolator protects your boat from electrolysis and what it misses your anodes, or zincs, will capture.

What to know when choosing a galvanic isolator.

It is important to choose a galvanic isolator rated for the amperage of power your boat uses. Galvanic isolators must be hard wired so an electrician might be a good investment. Galvanic isolators should be tested on a regular basis.
