A Guide to Solar Inverters: How They Work & How to Choose Them

What is a solar power inverter? How does it work? A solar inverter is really a converter, though the rules of physics say otherwise. A solar power inverter converts or inverts the direct current (DC) energy produced by a solar panel into Alternate Current (AC.) Most homes use AC rather than DC energy. DC energy is not safe to use in homes.
