What is an inverter?

A device which changes direct current (DC) into conventional alternating current (AC) power that you can use to operate all kinds of devices … electric lights, kitchen appliances, microwaves, power tools, TVs, radios, computers, to name just a few. You just connect the inverter to a battery, and plug your AC devices into the inverter … and you’ve got portable power … whenever and wherever you need it. The power inverter draws its power from a 12 Volt battery (preferably deep-cycle), or several batteries wired in parallel. The battery will need to be recharged as the power is drawn out of it by the inverter. The battery can be recharged by running the automobile motor, or a gas generator, solar panels, or wind. A very simple way to use an inverter for emergency power (such as during a rolling blackout), is to use a car battery (with the vehicle running), and an extension cord running into the house, where you can then plug in electrical appliances.
