Charging From AC Power

Using an Alternator Controller

If your regular alternator is inadequate by itself, you can install an alternator controller that will bypass the voltage regulator and boost the alternator’s output voltage during charging. This will increase the alternator’s charging rate at higher battery voltages and ensure more rapid and complete charging. Alternator controllers are available from marine product dealers.

Using a High-Output Alternator

Heavy-duty alternators rated from 100–140A can replace standard alternators and produce the higher current and voltage required to charge multiple battery systems. They are available from RV and marine dealers as well as auto parts suppliers.

Charging From AC Power

When recharging from AC power, use a good quality marine battery charger or RV converter that meets the requirements outlined in “Charging System Requirements” on page 38. For information about battery chargers manufactured by Xantrex, see the Xantrex web site at www.xantrex.com

Do not use chargers intended for occasional recharging of automotive starting batteries. These chargers are not intended for continuous use.
