Alternators are easily the most economic way to generate on board charge capacity. Having an alternator on board is an excellent alternative to an AC diesel, AC petrol or DC-generator, but your standard alternator will not suffice. These alternators are ideally suited for use as a powerful charging source for those vessels that have need for a tailored charging pattern. These alternators allowing you to rapidly finish charging and turn the engines off when moored without harming your battery bank. With a Charge Regulator the charge process will be handled safely and quickly. Power from the alternator is efficiently transferred to the batteries via the 3 step charge method. The charge voltage is automatically adjusted if there is any risk of gas formation. Electronics permanently regulate voltage, ensuring that the battery is always kept in good condition.
