Planning for AC Loads

AC load	AC load refers to an AC appliance you want to operate from the inverter/
	charger. Loads include most appliances that you can plug into a standard
	120 volt household electrical outlet.
Variables	The IP1012 AL inverter/charger can power a wide range of loads. The
affecting AC	size of the load and the length of time you can operate it depends on
loads	variables such as:
	•	type of load,
	•	ambient temperature,
	• size, state of charge, temperature, and condition of batteries.

The larger your battery capacity and the higher the state of charge, the longer the inverter/charger can run your AC loads. Battery capacity is reduced as battery temperature lowers.

Type of Loads

AC loads

	The way in which an AC load draws power may determine how
	effectively it can be powered from the inverter/charger.
Resistive loads	Toasters, coffee pots, and incandescent lights are examples of resistive
	loads which do not need a high start-up current to start running. They use
	a resistive heater element to generate heat or light. They are the simplest
	and easiest loads for an inverter/charger to run. Large resistive loads, such
	as electric stoves and water heaters, are impractical since their high power
	requirements quickly drain the batteries.
Inductive loads	TVs, VCRs, stereos, computers, and electric motors (power tools,
	vacuum cleaners, for example) are examples of inductive loads which
	surge on start up. They require a high startup current compared to a
	resistive load such as a toaster or coffee pot. Depending upon its size, the
	motor can take as much as six times of its operating current to start than it
	does to keep it running once it has started. This surge can sometimes
	exceed the inverter/charger’s maximum output rating and the inverter will
	shut down.
