Stand-alone inverter

Imagine you want to play with your toy car but you don't have any batteries. You know that if you put batteries in the car, it will start moving. Similarly, a stand-alone inverter is a device that takes the electricity from a battery and turns it into a kind of electricity that can be used to power things at home or at school. Just like how the batteries give power to your toy car, the battery gives power to the inverter and then the inverter gives power to the things that need electricity. This is helpful when you want to use your toy or something else without plugging it into the wall.
