How to choose this product

boat-alternator

A marine alternator is a mechanical accessory used to generate electrical power. It is designed to withstand the rigors of the maritime environment.

Applications

These devices can be installed directly on the main engine or on a generator set. A step-down/step-up alternator may be used along with a standard model to serve as a supplementary power source. Alternators are extremely useful when a vessel carries equipment with high power demands such as thrusters, windlass and air conditioning.

Technologies

A rotor equipped with carbon brushes revolves around a stator, producing induced current. The mechanism is driven by a belt from the main engine or the generator motor. Most internal combustion engines are equipped with a standard alternator.

An added step-down/step-up model can provide several hundred amperes for charging even the largest battery banks. A regulator allows it to generate the correct level of current needed for charging or for supplying the various loads.

How to choose

Determine electrical needs over 24 hours, both for charging and direct use, to calculate power requirements. Some supplementary power alternators are compatible only with specific engine makes and models. Be sure to supply this information to the manufacturer.

Advantages

- Fast and efficient charging
- Little or no maintenance required

Disadvantages

- Heavy
- Reduces engine performance
