PHOTOVOLTAIC WEAK-CURRENT ELIMINATION CIRCUIT AND ENERGY STORAGE POWER SOURCE

The present application relates to the technical field of power source protection, and mainly provides a photovoltaic weak-current elimination circuit and an energy storage power source. The photovoltaic weak-current elimination circuit comprises a discharge trigger module, a locking module, a discharge unlocking module and a discharge module, wherein the discharge trigger module is connected to the discharge module, the discharge unlocking module and the locking module, and the discharge module, the discharge trigger module and the discharge unlocking module are all used for connecting to a photovoltaic input source. The discharge trigger module is used for outputting a first control signal when an output voltage of the photovoltaic input source is greater than a preset voltage, so as to control the discharge module to discharge energy of the photovoltaic input source; and after the discharge module operates, by means of the locking module, the discharge trigger module maintains the output of the first contr
