1. On-Grid System Using Standard Grid Tie Inverter
1.1. The Grid Tie inverter converts DC power produced by Solar Panels to AC,
connects to the grid and feed all of the power available from the panels to the
AC load.
1.2. All excess power that is not needed by the load is then exported to the Grid.
1.3. If the Grid fails, then the Grid Tie Inverter will turn off. When the Grid comes
back on line. The Grid Tie Inverter will again supply power to the load and any
excess power is exported to the Grid again.
1.4. If the Solar Panel is producing less power and the GTI cannot deliver all the
power needed by the load, then power
will be supplemented by the Grid.
1.5. Power Meters (Except smart meter) are not aware of the direction of Power
flow. The user then pays for the power exported and delivered by the Grid.
