A split-phase hybrid inverter makes 120/240 V from a single box, the same service a US house gets from the utility, so it can run 240 V loads such as a well pump, a heat pump or an electric dryer. These are the inverters for whole-home backup and grid-tied solar with a battery. For a permitted, grid-connected install, check for UL 1741 listing (UL 1741 SB in most states now), which utilities and inspectors usually require.
