What does a Grid Connected (grid tied) system mean?
Part of the situation implicit in a PV power system is that energy is produced during the daytime only, while it is used day and night. How to deal with this situation? Typically there are two solutions, depending upon the circumstances of the installation. Either one dumps extra power during the day into some resevoir, typically a battery backup system; or one uses an inverter which can also be connected to the electric grid. In this latter case, one pumps excess power into the public grid during the day, and withdraws it at night. This is called a grid tied system. Note that each jurisdiction and electric power company will have its own rules and regulations for setting up a grid tied system.
