WIPO Patent Application WO/2023/038171
Kind Code:
A1
Abstract:
The present invention provides an intelligent photovoltaic device capable of abnormality diagnosis and predictive control, comprising a junction box, an external sensor unit, a network and a monitoring unit, wherein the junction box comprises: a circuit unit, which is connected to a solar cell array formed by connecting solar cell modules, so as to be capable of transmitting, to an inverter, power generated by solar cells or blocking same; an internal sensor unit connected to the circuit unit to measure the current, voltage, and temperature of a constituent element in the circuit unit; a control unit, which receives information about the external sensor unit and the internal sensor unit, so as to predict the temperature of the constituent element in the circuit unit, and determines whether the constituent element is abnormal to generate a control signal; and a display unit, which receives information about the control unit to display same to the outside so that a manager can be aware of the existence of an abnormality.
