Grey: grid (positive or negative): imported or exported – measured  
Blue: consumption of electrical appliances in the facility -calculated (always positive) if the green curve is negative, please reverse the direction of the CT measuring the PV production, if the blue curve is negative, please reverse the direction of the CT measuring the grid import / export
