Step 2. The battery inside an inverter is a rechargeable secondary cell (commonly a lead-acid battery of the type described in section 5.10.2, or increasingly a lithium-ion battery), charged from the mains supply whenever mains power is available.
Step 3. When mains power fails, the inverter's electronic circuit rapidly switches the battery's DC output back and forth (an oscillator circuit), and a step-up transformer raises this switched signal to mains voltage, producing a usable AC waveform. …
