If the source (grid) starts to fall in frequency the inverter will
either have to keep in step with it or supply massive currents as the
phase difference between the inverter and the grid begins to increase.
If the inverter tries to stay on-frequency, the time will come when they
are 180-degrees out of step, then things will get far too exciting.
