While all of Balmar's high-output alternators are designed and recommended for use with our multi-stage voltage regulators, the 6-Series Alternator utilizes Balmar's Smart Ready®Technology.

If battery loads are relatively small and your engine is running frequently, the alternator's internal regulator may be suficient to support your electrical needs without external regulation.

If your vessel utilizes larger deep-cycle battery banks or the engine's duty cycle is less frequent (as is the case in most sailing applications), the 6-Series Alternator combines and works seamlessly with Balmar's ARS-5 Voltage Regulator or Max Charge Voltage Regulator.

Purchased either as a charging kit or individually, 6-Series Alternators can solve a multitude of charging problems at a reasonable price. All kits come with alternator, regulator and two temperature sensors.

What to consider before you buy...

Before you invest in a high-output charging system, save yourself a lot of trouble and money by ensuring that you buy the correct system for your application. Charging systems vary by type of boat, and a long list of other variables including engine type, engine room space, belt type and size, battery bank size and battery chemistry.
