What Will a 1500-Watt Power Inverter Power?

A 1,500-watt inverter will power approximately the same appliance load that a standard U.S. 120 volt wall outlet will power. This may power a few small appliances, but would not be enough power to supply a larger appliance, such as an electric range.

What Is An Inverter?

A typical toaster may draw more than 1,000 watts.

A power inverter is an electrical device used to convert direct current (dc) power into alternating current (ac) power. Common uses include converting solar (photovoltaic) system-generated power and 12 V battery power into power usable by standard appliances.

Typical Power Draws

According to Solar Energy International, here are some representative possible combinations adding up to 1,500 watts:

(a) One window air conditioner (1,000 W) and a refrigerator (475 W).

(b) Four 100 W light bulbs (400 W), a laptop computer (120 W), a refrigerator (475 W), a gas clothes dryer (300 W), a 25 inch TV (130 W), and a stereo system (50 W).


A 1,500-watt inverter will not supply enough power for certain appliances, such as electric clothes dryers (4,000 W). Also, for appliances with electric motors, make sure the surge capacity of your inverter is at least three times the regular rating, because electric motors temporarily draw much higher currents when they are started (for example, a 1,500 W inverter should have a minimum surge rating of 4,500 W).
