The most sophisticated - and, therefore, most expensive - inverters use the most steps to produce a true or near true sine wave, and, as a result, are the type most found in residential PV systems. As more sensitive electronics such as computers were introduced into homes, these became standard for residences.
The Various Applications Of Inverters In off-grid applications, DC electricity is stored in batteries. An inverter then converts the electricity from the batteries into usable AC electricity. The inverter must be large enough to power all the appliances and devices that will be running at the same time, and must be able to handle surges of power from clothes and dish washers, dryers, etc.
As you can see, an inverter is essential if any or all your electricity comes from solar panels. Advances in inverter technology are being made all the time, with the main drawback being the lack of efficiency, since most inverters operate at only 90-95% efficiency.
Knowing the internal workings of an inverter is not vital, but selecting the right inverter for a particular application is, so consulting a solar professional or company on the right inverter to buy is extremely advisable.
