description The invention relates to a method for a voltage boosting device isolated from a power grid and applied to a solar power station. A solar cell, an inverter, a circuit breaker unit and the voltage boosting device are included. An output signal line of the voltage boosting device is in signal connection with the circuit breaker unit. An AC detection device is arranged in the inverter and is conductively connected with the negative electrode of the DC end of the solar cell. The circuit breaker unit comprises a plurality of circuit breakers, and each circuit breaker is arranged between the AC detection device and the power grid. The defects in the prior art are overcome. The circuit breaker unit is arranged between the AC end of the inverter and the power grid. When the voltage boosting modulestarts to work and recovers and prevents PID, the circuit breakers are opened, and the inverter is disconnected from the power grid, so that no voltage is applied to the AC detection module, and damage to internal devices of
