Planning for AC Loads
DC loads
DC loads are those that run off a 12 volt electrical system. A few examples of DC loads are:
•marker lights, headlights, vehicle lighting, other lights using DC power
•DC refrigerators
•VHF radios
•
•pumps, lights, fans, power vents, LPG leak detector, toilet, and some water heaters.
DC loads and the inverter/charger both rely on the batteries for power. Many DC loads running at one time will shorten the operating times of AC loads.
Problem loads
Problem loads are loads you should not operate from the inverter/charger because they may be damaged or may not operate properly:
•dimmer switches
•some small rechargeable
•small
•variable speed motors
Ambient Temperature
Ambient | The ambient temperature, that is, the air temperature around the inverter/ |
temperature | charger, will affect its output power. |
| Ambient temperature can rise when the vehicle is exposed to hot weather |
| conditions or cabin heat from heaters. |
Temperature | Generally, the output power decreases as the temperature increases. For |
and power | example, at 77 °F (25 °C) the unit delivers 1000 watts for as long as you |
| have sufficient battery power. At 104 °F (40 °C) it delivers 1000 watts for |
| up to 30 minutes before shutting down, 2000 watts for 2 minutes, or 750 |
| watts continuous. |
