What is a Power Inverter ?
A power inverter is an electronic device that converts low-voltage DC (direct current) power to standard household AC (Alternating current) power. An inverter allows you to operate household appliances and electrical equipment using the power produced by a car, truck or boat battery or renewable energy sources, such as solar panels or wind turbines.
The Input voltage, output voltage and frequency, and overall power handing depend on the design of the specific device or circuitry. The inverter does not produce any power, the power is provided by the DC source.
A Power Inverter can be entirely electronic or may be a combination of mechanical effects (such as a rotary) apparatus and electronic circuitry. Static inverters do not use moving parts in the conversion process.
These are the definitions of power inverter from Wikipedia. Even I have read it, I still can not understand what is a Power Inverter.
A Power Inverter changes DC power from a battery into conventional 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 Inverter draws its power from a 12 Volt battery (preferably deep-cycle), or several batteries wired in parallel. The battery will need to 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. Or you can use a battery charger plugged into an AC outlet to recharge the battery.
And also you can use the Power Inverter for emergency home backup power too. A very simple way to use an inverter for emergency power (such as during a power outage), 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.
