A photovoltaic intelligent power supply comprises multiple unit modules, a communication unit (103) and a control unit (106). Some unit modules are connected to the control unit (106) and the communication unit (103). Each unit module comprises an input aggregation unit (101), a data collection unit (102), a voltage step-up unit (104), an arc isolation unit (105), and an anti-PID unit (107). The input aggregation unit (101) is connected to a photovoltaic component. The data collection unit (102) is used to collect voltage and current state signals. The voltage step-up unit (104) is used to perform alternate chopping and works in an MPPT mode. The arc isolation unit (105) is used to receive an instruction delivered by the control unit (106) to perform opening and closing. The anti-PID unit (107) is used to receive an instruction delivered by the control unit (106) to form a suitable direct current voltage to be applied between a negative electrode of a battery panel and the ground. The photovoltaic ...
