A power inverter is disclosed. The power inverter includes an electronic switching circuit designed to be electrically connected to a DC power supply. A power inverter circuit is electrically connected to the electronic switching circuit for converting a DC supply voltage to an AC voltage and has output terminals to output the resulting AC voltage. The power inverter further includes a microprocessor having an oscillating circuit provided therein for counting time. The microprocessor is constructed to be able to send a control signal to the electronic switching circuit at a desired time to order the electronic switching circuit to break the power inverter circuit.
