I have recently installed solar system that adds energy to the grid. My utility company has installed bi-directional meter at my place to record energy consumed as well as energy added to the grid.
Energy consumed is recorded in meter as kWh which is pretty usual however energy added to grid is given in kVARh, I assume they call it reactive energy. Meter provides positive active energy and positive reactive energy readings.
Is there a way I can calculate how many units I have added to the grid?
