Managed network system
Mains photovoltaic system with a capacity of 4.0 kW, 10 micro inverters and control that controls the direction of electricity. The computer control monitors the power factor (cos φ) and when the direction of electricity changes (from 'house' to 'mains') it starts to turn off the power to the microinverters until the power leak to the 'mains' stops.
