Claims

[Scope of utility model registration request]

a solar cell, a shunt device connected between an output terminal and a return of the solar cell, a first diode whose anode is connected to the output terminal of the solar cell, and a shunt device connected in series to the cathode of the first diode. a solar array current monitor whose output end constitutes a power bus, a charger and a storage battery connected in series between the power bus and the return, and a second battery connected in parallel with the charger such that its cathode is connected to the power bus. In a power supply system including a power supply device and its load, which is composed of a bus voltage monitor and a capacitor bank connected in parallel between a power supply bus and a return, the output signals of the solar array current monitor and the bus voltage monitor are When it is detected that the output signal of the solar array current monitor is smaller than a certain threshold and the output signal of the bus voltage monitor is also smaller than another certain threshold, it is determined that the area is in the shade, and the load on the power supply system is A power supply device comprising a shade determination device that sends a load reduction command signal to the load in order to control the amount of load reduction.
