An inverter system includes inverting circuitry for inverting an input DC signal into a square wave or quasi-square wave AC signal across a resistance, and a controller for causing the inverting circuitry to invert the input DC signal into the AC signal. The DC signal is a DC voltage having a value that ranges from 24-32 volts DC. The AC signal is an AC voltage having a value that ranges from 115-230 volts AC RMS.
