A hybrid inverter is an all-in-one inverter that incorporates both a solar and battery inverter in one simple unit. This enables storage of excess solar energy in a battery-system for self-use. Hybrid inverters function like a common grid-tie solar inverter but can generally operate in one of several different modes, depending on the application. This includes battery backup mode, which provides a limited level of backup power in the event of a blackout. Most hybrid inverters can operate without a battery and function like a grid-tie solar inverter by exporting excess solar energy to the electricity grid.
