I understand that the grid-tie inverter produces a higher voltage than the grid to force the current into the grid.
Would a second grid-tie system not cause a race condition where they try to out-raise each other ? Is that what

Is it possible to have 2 grid-tie systems ?
I currently have a 10kW SolarEdge grid-tie system and would like to add more capacity with a separate/new grid-tie system.
Can they both be connected to the same panel in parallel ?
Would they still shut down when the grid is off ?
