A grid-tie inverter is a power inverter that converts direct current (DC) electricity into alternating current (AC) with an ability to synchronize to interface with a utility line. Its applications are converting DC sources such as solar panels or small wind turbines into AC for tying with the grid.
Off grid inverters are used in renewable energy systems that are not connected to the utility grid.
Hybrid inverters operate on grid (grid-tie) as well as off-grid, hybrid (both on-grid and off-grid at the same time) and Backup (in case of a black out).
