An inverter is a device that is used to turn direct current (DC) power into alternative current (AC) power. It can be either a true sine wave inverter or a modified sine wave inverter. If you use a true sine wave model, the power you are getting is the same amount (or maybe even a little more) than you would get from the electric company. A modified sine wave model will suffice for almost any of your needs, but it will give you slightly less power.
A DC-to-AC inverter does all the work of turning naturally occurring direct energy into alternative energy. It allows the user to run AC devices on a DC power source by changing the way the energy flows.
For home use, a modified sine wave will be able to handle the demands placed on it by laptop computers, cameras, VCRs and DVD players. The 300-watt variety works very well for this type of workload. Larger appliances can be run on a 600-watt inverter, including small cooking devices and small power tools.
If you go up to 1,750 watts, your inverter can provide power for much bigger devices, from toaster ovens to microwaves. As you reach the 3,000-watt mark, you may need to look into alternative wiring options to ensure that your inverter works perfectly and safely. You can run practically anything of normal household size on an inverter with this amount of power.
For fancy equipment, true sine wave inverters are necessary to get the best results. For example, the serious gamer with a queue of graphically intense video games, will get a lot of enjoyment out of a true sine wave inverter.
If you run a power inverter in your car, you are indebted to Vector, a company that made great strides in this field. A Vector inverter is a good option for the power needs that arise when you are on an extended vacation. Some inverters even prepare ahead of time for possible energy lapses and will not shut off in most cases.
Lastly, for those who use an inverter often, an inverter charger might be a good investment.
