Inverters
There are two common types of Grid-Tie renewable energy systems: Basic Grid-Tie and Grid-Tie with Battery Back-up, also known as Grid-Interactive.
Basic Grid-Tie System A basic Grid-Tie solar system generates electricity when the sun is shining. It supplies this power to your house and sends any excess back to the utility. It does this by inverting the DC power produced from the solar array into grid compatible AC power which is then sent to your main electrical panel to by used by your household appliances while any excess power is sold back to the utility.
Grid-Interactive Just like a basic Grid-Tie system, a Grid-Interactive solar system generates electricity when the sun is shining and supplies this power to your house while sending any excess power back to the utility.
Where a Grid-Interactive system differs from a Grid-Tie system, is in its ability to charge batteries which are used as a back-up source when the power goes out. In the event of a grid power outage uninterrupted power is supplied to important household loads such as refrigerators, lights, and computers while your solar array continues to produce power and charge your batteries.
