Inverters

Inverters are a basic component of any independent power system that requires AC power. An inverter converts DC power stored in batteries into AC power used to run conventional appliances like computers, fridges, power tools and entertainment systems.

Inverters differ in the quality of electricity they produce. Quality can vary in waveform, frequency and voltage. The type of appliance that can run off an inverter depends on the quality of electricity converted.

Jargon
Waveform: Represents how AC electricity varies with time.
Frequency: Number of complete cycles per second of an AC current. Standard unit is Hertz (Hz).
Harmonics: Varying frequencies within one wave cycle. The more harmonics, the worse the quality of the electricity.
Rated power: The maximum power output of an inverter.

Sub  CATEGORIES   Modified Sine Inverter Modified sine wave inverters are a popular option with slightly compromised wave (some harmonics) at a lower cost. They approximates a true sine wave with low harmonics that do not cause problems with household equipment. • Main disadvantage is peak voltage varies with battery voltage. Inexpensive electronic devices with no regulation of power supply may behave erratically when battery voltage fluctuates. • Not all modified sine wave inverters are created equal. A high quality modified sine wave inverter such as the Xantrex DR series will run 99% of loads without a problem. Sine Wave Inverters Sine wave inverters are the ultimate inverter. They produces electricity similar to or better than utilities with virtually no harmonics. • Will run any appliance - typically used to run appliances sensitive to other waveforms like computers and electronic entertainment equipment. • More expensive than modified sine wave inverters Grid-Inertie Inverters • Designed to “sell” power back to the utility when there is a surplus. • Certified products available off the shelf and easy to use. • Available with or without batteries depending on your needs. Power Panels Power panels are the ultimate in installation convenience. Choose from a wide variety of inverter, controller, transformer and other options. Have the whole unit custom-assembled for your installation. Portable Inverters Portable battery / inverter systems provide the ultimate in convenience in an easy, all-in-one package.
