An inverter can be used for various applications, and its purpose is to convert direct current (DC) into alternating current (AC). Power inverters can be used with renewable energy systems, off grid, backup source of power, marine and RV systems, and much more. This device requires a stable source of DC power, so that it can provide the currents that are required by the system it is hooked up to.
Depending on the type of application you are powering, all aspects of the inverter will vary. This includes, input and output voltage, frequency, and overall power. This device is not designed to supply actual power, as it converts input DC power into output AC energy. Almost all electronic devices require AC power, and not all power sources supply this type of electrical current. That is why an inverter is so important. Otherwise, you would not be able to use your source of power to supply energy to your applications.
The input voltage that is needed will vary according to the design and purpose of the inverter. 12 Volt Inverters will usually get its power from a 12 volt lead acid battery that is rechargeable. 24 or 48 volt inverters are most often used with renewable energy systems. Inverter voltages can reach up to the hundreds of thousands, at which point it would become a part of a high voltage direct current power transmission system.
There are various types of waveforms that inverters use, including:
- Pure Sine Wave – Waves that flow in even curves. These waves are produced by rotating AC machinery. They are a natural result of this process, and that is why they are referred to as “Pure”.This is the closest you will come to getting a wave that is produced by a utility company or a generator. New age devices will all require pure sine waves to operate correctly. It provides the most stable wave of energy, but they are also the most expensive type of inverter.
- Modified Sine Wave – Tend to be more square, but will work for most equipment. Applications will use more power from the inverter, because the power being supplied is low in efficiency. This waveform is cheaper in price, but also a bit noisier. It will supply power in peaks, which means it will create more heat.
Various manufacturers offer inverters, but it is really important that you consider the size of your power system before you make your purchase. As this will ensure you have enough currents to efficiently supply the energy that you need and want.
