When most people hear the words “power inverter,” it makes them think of some high-tech gadget that they'll never have to use. But the truth is that a 3000 watt power inverter is not really all that high-tech, and even technophobes can easily use one. The basic purpose of an inverter of this size is to convert DC (direct current) power to AC (alternating current) power so that you can run AC-compatible devices on DC power sources. These units are easy to find and relatively affordable. If you are going camping and need power, you shouldn't leave home without one.
The difference between DC and AC is that direct current provides a unidirectional flow of electricity, and alternating current provides electricity that flows from one direction to the other at regular intervals. AC is actually the more efficient to produce of the two, which explains why most of the world uses AC power and most electrical devices are designed for use with AC power. But there are still DC power sources out there (batteries, solar cells, thermocouples), and if you have one, you'll need a 3000 watt power inverter in order to use your AC devices on it. Fortunately, a good unit of this size is within reach.
A good 3000 watt power inverter is the perfect way to make sure that you have the power that you need in order to bring your favorite electrical devices along with you on the go. Many people who own a unit with this amount of wattage like to go camping, boating or RVing. This allows you to bring along a simple DC power source, which is more portable than AC, and convert it to AC for use with all of the standard electrical devices that you could dream of using. It's no wonder that they're so popular with people on the go.
If you want to be sure to purchase the right 3000 watt power inverter for your needs, then you first have to ascertain what your needs are, exactly. This means that you have to have a good feel for the types of devices you'll use with your unit, where you'll be keeping your inverter, and even how quietly you'll need it to run. The more features you add, the more expensive it'll get, so you want to make sure to find an inverter with a good balance between simplicity and capacity.
