C
Alternators and Charging
Systems
Appendix C provides guidelines for recharging batteries from an
alternator, from AC power, and from alternate energy sources.
A good charging system is important for the health of your batteries. Poor
recharging methods can quickly damage batteries.
Charging System Requirements
Your charging system should be capable of delivering a charging current
equal to 25% of the amp-hour capacity of your battery. For example, if
you have a 200 Ah battery, the charging system should be able to deliver
50 amps. The charging system must also be able to charge each 12 volt
battery up to approximately 14.4 volts and then drop back to a “float”
voltage of 13.5–14 volts (or shut off).
CAUTION
Never operate the inverter directly from an alternator. To work properly, the
inverter must be connected to a battery or a well-regulated, high-current DC
power supply.
