Which inverter type is described as interacting with the utility grid to coordinate power exchange?

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

Answer: (C)

Coordinating power exchange with the utility grid requires a grid-aware inverter that synchronizes with the grid’s voltage and frequency and adjusts its output accordingly. An interactive inverter is designed for this role: it stays connected to the grid, can export or import power as needed, and can provide grid-support functions while following the utility’s control requirements. Standalone inverters operate in isolation and don’t coordinate with the grid, so they can’t exchange power with it. Central describes the physical layout rather than grid interaction, and multimode can switch modes but doesn’t inherently capture the grid-coordination feature. Therefore, the inverter type described is interactive.
