Grid Tied Solar Inverters. A grid tie inverter is an electrical device that allows solar power users to complement their grid power with solar power. It works by regulating the amount of voltage and current that is received from the direct current solar panels (or other D.C. energy source) and converting this into alternating current. The main difference between an inverter and a grid tie inverter is that the latter also ensures that the power supplied will be in phase with the grid power. This allows individuals with surplus power (wind, solar, etc) to sell the power back to the utility. This is sometimes called "spinning the meter backwards" as that is what literally happens.
Many states have introduced laws that make it necessary to have your grid tie inverter inspected and approved before you can begin to sell power to your utility provider. A number of states also require you to install a meter that measures power coming into your residence from the power company as well as the amount going out. Before proceeding with setting up your own grid tie inverter, be sure to check with the local authorities to save yourself potential hassle down the road.
A grid tie inverter monitors the power from the grid and makes sure the power coming from your inverter stays in sync with the phase of the electricity from the grid. Keeping the phase in sync isn’t the only thing that a grid tie inverter does, however. You can think of electricity as flowing downhill.
