What is the primary purpose of interconnection standards for grid-connected generation?

• A. To ensure that distributed generation is allowed to connect with no restrictions.
• B. To ensure safe backfeeding into the grid and accurate billing when connecting distributed generation.
• C. To maximize solar energy production regardless of grid stability.
• D. To dictate warranty terms for PV modules.

Answer: (B)

Interconnection standards define how a grid-connected generator, like a rooftop solar system, must connect to the utility grid so that the system can be added safely and predictably. The key aim is to ensure safe backfeeding into the grid and accurate metering for billing. Safe backfeeding means the system must not energize the lines when the grid is down or when utilities are performing work. Protection schemes, anti-islanding capabilities, and proper interconnection equipment prevent backfeed from creating hazards for workers, causing equipment damage, or destabilizing the network. At the same time, metering requirements ensure that the energy you export and import is measured correctly, so billing or credits (net metering) reflect the actual amount of energy exchanged with the grid. These standards don’t determine warranty terms or aim to maximize solar production regardless of grid conditions. They’re about safe, compatible connection and accurate accounting, which supports grid reliability and fair charges for customers.
