A power inverter is a key piece of solar equipment and unlike solar panels, which are intuitive to understand, inverters make it sound like you need to make a trip back to high school physics class. Understanding how a power inverter works requires putting meaning into the words "power" and "inverter."
Generally speaking, the point of a solar panel is to create electricity through the renewable, limitless energy of the sun. That's the "power." But how do you get the power from the solar panel to your appliances?
An inverter. Its primary function is to "convert" battery power into AC current. If you have any familiarity with car batteries, an inverter won't be intimidating in the end.
