To take full benefit of an independent electrical system, a power inverter – a complex piece of electrical hardware – is very essential. It converts battery supplied power (DC) into an oscillating type of electricity (AC), which is needed to run nearly all devices in and around the house. A 12 volt power inverter is a method of inverting or changing 12 volts to 115 volts. Other power inverter voltage ranges, such as 24 volt input and 240 volt output, are also available.

12 volt power inverters come in many types and sizes. In addition to providing the alteration of one power type to another, they are constantly modified to provide better efficiency and stability. These devices are used to produce the same kind of power made from generators and utility companies.

A 12 volt power inverter enables you to run all home and office appliances, such as microwaves, central heating pumps, lighting, tropical fish aquariums, DVD theaters, fax machines, laptops, etc. Since they are good standby power sources, the inverters are extremely useful during power cuts. They are also ideal for use in your caravan, motor home, boat or RV.

The most common types of 12 volt inverters are modified sine wave inverters or modified square wave inverters. Another variety is a true sine wave inverter that provides utility grade power. Occasionally it offers a better quality than utility grade power. Pure sine wave inverters can power any appliance inside its power range. It is used in most RV and marine 12 volt power inverters.

Once you have decided to buy a 12 volt power inverter, think about what power (wattage) it should be carried. The total wattage is calculated as a product of current and voltage (i.e. Amps x Voltage = Watts). It is wise to purchase a little larger power inverter than you need.

12 volt power inverters are usually connected through a cigarette lighter or hard wired to the battery. Over 300 watts needs a direct battery connection. A good unit features under and over power shield and also low battery alarms. Read and follow your manual for safety and proper installation of your 12 volt power inverter.
