Abstract

The system comprises: a static switch (16) between an A.C. current supply network mains (12) and a load (10), the switch being controllable to connect or isolate the load from the mains; a voltage booster (20, 22, 24) connectable to the output of a set of photovoltaic panels (18); a static DC/ AC converter (26), connectable to the voltage booster (20, 22, 24) for generating a voltage at 50Hz; a static switch (47) from the output of the static converter (26) to the load (10), and controllable to connect or isolate the load from the photovoltaic generator; and a controller (30) receiving voltage, current and power signals from respective sensors (32, 34, 35, 36, 38, 39, 40, 45), and which is programmed to control the switches in order to instantaneously connect and isolate the load with respect to the mains or the photovoltaic panels, depending on circumstances.
