Grid tie inverters, which match phase with a utility-supplied sine wave. Grid-tie inverters are designed to shut down automatically upon loss of utility supply, for safety reasons. They do not provide backup power during utility outages....
A square wave inverter will run simple things like tools with universal motors with no problem - but not much else. These are seldom seen any more except in the very cheap or very old ones....
