Balmar 604-Series Alternators deliver high-output performance in a compact case. While all Balmar’s high-output alternators are designed and recommended for use with their multi-stage voltage regulators, the 604-Series Alternator utilizes Balmar’s Smart Ready® Technology. Smart Ready® internal regulation enables the alternator to be used as a stand-alone, charge controller that is ideal as a built-in backup regulator for the cruiser, or as a full-time regulator for systems where Smart Multi-Stage Regulation is not required.  If battery loads are relatively small and your engine is running frequently, the alternator’s internal regulator may be sufficient 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 24 Volt 6-Series Alternator combines and works seamlessly with Balmar’s MC-624 Voltage Regulator.
