The main function of an inverter is to convert direct current (DC) into alternating current (AC), and to change the voltage level into a stable 120 or 240 VAC that can be used by household appliances or "sold back" to the utility grid. The word "inverter" was originally used because the output wave form produced by its circuits alternates between a positive and a negative voltage. This device "inverts" the polarity of the power source (typically, a battery or PV array), causing the current to flow in alternating directions through the load. Hence the term "alternating current".

In essence, an old-fashioned mechanical inverter boils down to a switching unit connected to an electricity transformer. If you've studied our article on transformers, you'll know that they're electromagnetic devices that change low-voltage AC to high-voltage AC, or vice-versa, using two coils of wire (called the primary and secondary) wound around a common iron core. In a mechanical inverter, either an electric motor or some other kind of automated switching mechanism flips the incoming direct current back and forth in the primary, simply by reversing the contacts, and that produces alternating current in the secondary-so it's not so very different from the imaginary inverter I sketched out above. The switching device works a bit like the one in an electric doorbell. When the power is connected, it magnetizes the switch, pulling it open and switching it off very briefly. A spring pulls the switch back into position, turning it on again and repeating the process-over and over again.
An inverter is an electrical device for converting 12-volt DC battery power into 220 volt AC power. Inverters are available in sizes ranging from as low as 30 watts up to 4,000 watts or more. For pratical purposes, an inverter size of 2,000-3,000 watts will be needed (or will already be installed) in an RV.
There are two basic kinds of inverters:pure sine wave inverter and modified sine wave inverter. pure sine wave is what comes out of the wall. Modified sine wave is basically a square wave with the corners smoothed a little. Most stores only carry modified sine inverters because they are a lot cheaper. Operation of an inverter is, for the most part, automatic, although most require some settings to be programmed. When shore &/or generator power is lost, the inverter senses this and provides its own power to maintain an uninterupted power source. When shore power is restored or the generator started, the inverter will again sense this and, usually after a short delay, will automatically switch shore or generator power to the RV.
