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

•factory-installed radios or sound systems

•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 hand-power tools

•small battery-operated appliances such as flashlights, razors, night lights

•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.
