Галерия - Zero feed-in grid-tie system

 

4.0kW grid connected photovoltaic system with 10 microinverters and a management board, that controls the direction of electricity. Computer controlled management board monitors the power factor (cos φ) and when the direction of electricity changes (from the 'house' to the 'grid') it starts to turn off the power of the microinverters consecutively, until electricity fed into the 'grid' is equal to 'zero'.
