Photovoltaic energy-storage inversion control integrated machine short-circuit and overload protecting circuit

The utility model discloses a photovoltaic energy-storage inversion control integrated machine short-circuit and overload protecting circuit. The protecting circuit mainly comprises a current Hall sensor, an adder, two comparators and two resistor voltage-dividing type reference voltage circuits. After the current Hall sensor converts measured output current signals into voltage signals through a resistor, a voltage signal Ub is acquired by means of the adder. The voltage signal Ub is simultaneously sent to the cathode input end of one comparator and the anode input end of the other comparator through a resistor. The two resistor voltage-dividing type reference voltage circuits supply a reference voltage to the two comparators respectively. The output ends of the two comparators are electrically connected with a master control one-chip microcomputer through a protecting signal. By means of the above-mentioned inversion output short-circuit protecting circuit, the short circuit and overload protecting currents
