    摘要： This application provides a photovoltaic inverter and a temperature detection apparatus. The photovoltaic inverter includes a plurality of photovoltaic terminals, a converter, a PCB circuit board, a temperature detection circuit, and a controller. The plurality of photovoltaic terminals are correspondingly connected to a plurality of photovoltaic modules. The PCB circuit board includes an electrically conductive layer and at least one thermally conductive insulation layer. One end of each photovoltaic terminal is soldered on the PCB circuit board, and the other end is connected to a corresponding photovoltaic module in a thermally conductive manner. The electrically conductive layer transmits electric energy generated by the plurality of photovoltaic modules to the converter. Each thermally conductive insulation layer conducts heat generated by at least one photovoltaic terminal. The temperature detection circuit detects a temperature of each thermally conductive insulation layer. The controller obtains a temperature of each of the plurality of photovoltaic terminals based on the temperature of each thermally conductive insulation layer. The temperature of the photovoltaic terminal is detected by using the temperature detection circuit, so that an actual temperature of the photovoltaic terminal can be monitored in real time before the photovoltaic terminal catches fire, to ensure reliability of entire photovoltaic power generation.
