You can't prevent a grid tied inverter from sourcing energy to the grid, although it may violate contract terms. A simple mechanical energy meter will rotate backwards in this case.

In practice, the energy company won't get aware of it as long as your total bill is in an expectable range.

You're right in case of mechanical it will rotate in reverse direction, but we have Digital Meters and they never go beyond 0. But i want to ask if both Grid Tie Inverter + main line available ? then who will supply the load ? grid + main / 2 ? or grid 1st or main 1st ?
