A(n) ___ inverter has the capability of operating as either off-grid or grid-tied.

A(n) ___ inverter has the capability of operating as either off-grid or grid-tied.

• A. Multimode
• B. Standalone
• C. Interactive
• D. String

Answer: (A)

The key idea is a device that can operate in multiple configurations depending on whether the grid is available or not. A multimode inverter is built to handle both off-grid (islanded) operation and grid-tied operation, and it can switch between these modes as conditions change. This makes it ideal for systems with battery storage or backup needs, where you might want to run independently when the grid is down and still feed power to the grid when it’s up. A standalone inverter, by contrast, is designed for off-grid use only and can’t connect to the utility grid. An interactive or grid-tied inverter is focused on grid-connected operation and may not be designed to island safely or seamlessly; it usually won’t run in off-grid mode. A string inverter is a type of inverter classified by how it handles PV strings, not by its operating mode, so it doesn’t define capability to be both off-grid and grid-tied. So the multimode inverter best fits the requirement.
