While a standard grid-connected system might run $15,000-$20,000, a complete off-grid setup typically ranges from $45,000-$65,000 for an average home. This significant price difference reflects the additional components needed when you can't rely on the utility grid as backup.

The key role of the grid-interactive or synchronous inverters or simply the grid-tie inverter (GTI) is to synchronize the phase, voltage, and frequency of the power line with that of the grid. Solar grid-tie inverters are designed to quickly disconnect from the grid if the goes down. In the United States, for example, this is an requirement that ensures that in the event of a blackout, the grid tie inverter will shut.
