Smart Regulators For Car Alternators

Car alternators don’t typically make good battery chargers for off-grid homes. The deep cycle battery requires special charging to maintain a long life, as it gets discharged and recharged deeper, and more often than a car battery. There is hope, however, for the ubiquitous car alternator. By driving it with a small engine, and adding a smart regulator to vary it’s field coils, you now can build a high amperage portable battery charger, as we have outlined in our eBook at http://www.green-trust.org/ebooks/. The Smart Regulator of choice is the Ample Power SARV3. It includes the ability to also charge a starting battery, control two alternator fields connected to the same engine, and offers battery temperature compensation. We highly recommend it.
