How correct reactive power settings on your inverter can increase

How this works is if the voltage is too high your inverter can be set to import reactive power (which tends to lower grid voltage) if the voltage is too low your inverter can be set to export reactive power (which tends to raise grid voltage). Note this is all happening over one AC cycle i.e. in a 50th of a second if the grid frequency is 50 Hz.
