Planning for AC Loads

Running the Alternator While Operating AC and DC Loads

Recharging

Running the alternator does not guarantee that the battery is being fully

 

recharged by the alternator if you are running a combination of large AC

 

and DC loads.

 

The alternator must provide more power than the draw of the combined

 

DC and AC loads for your battery to fully recharge.

Example

This example for a 12 volt battery shows what happens if the alternator is

 

overloaded.

Figure 2-2AC and DC loads powered by the alternator

The alternator is charging at 130 amps while the engine is running and there is a 1000 W (AC) load.

The efficiency of the inverter/charger is approximately 90%, which means it is drawing about 1100 W (DC) from the battery or 92 amps. This leaves 38 amps for all DC loads. If the DC loads require more than 38 amps, the battery will actually discharge even though the alternator is running.
