Charging From AC Power
B–3
Using an Alternator Controller
If your regular alternator is inadequate by itself, you can install an
alternator controller that bypasses the voltage regulator and boosts 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 100–140 A 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 B–2. For information about
battery chargers, visit our 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.
Charging From Alternative Energy Sources
You can also charge your batteries from alternative energy sources such
as solar panels, wind, or hydro systems. Make sure you use the
appropriate battery charge controller for your particular energy source.
CAUTION
Never operate the PROwatt 3000 directly from an energy
source such as a solar panel. The inverter must be connected to
a battery or a well-regulated, high-current DC power supply to
work properly.
