1. An installation test circuit for a photovoltaic (PV) system with rapid shutdown, the installation test circuit comprising:
a voltage generator, which is coupled to a solar panel in the PV system, and generates a first output voltage and a second output voltage according to a first control signal, a second control signal and a voltage source outputted by the solar panel, wherein a voltage difference between the first output voltage and the second output voltage is less than or equal to the voltage source,
wherein the first control signal and the second control signal control the voltage generator to determine the first output voltage and the second output voltage; and in an installation test mode, the voltage difference between the first output voltage and the second output voltage ranges from about 0.6 to 1.0 volts.
