A(n) ___ inverter connects or interacts with the grid.

A(n) ___ inverter connects or interacts with the grid.

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

Answer: (C)

Inverters that connect to and coordinate with the utility grid are designed to run in step with the grid’s voltage and frequency and to follow grid conditions. This kind of inverter is grid-aware, feeding power into the grid when available and complying with grid codes, including anti-islanding protections that prevent backfeeding during a outage. That behavior—actively connecting to, monitoring, and reacting to the grid—defines an interactive inverter. Standalone inverters, by contrast, operate independently from the grid and do not interact with it. Central inverters describe a scale or architecture rather than how they relate to the grid. Multimode can operate in several modes, but the phrasing here points to the inverter whose purpose is to connect to and interact with the grid, which is why the interactive type is the best fit.
