Which components are involved in interconnection for an on-grid PV system?

• A. Interconnection equipment and utility meter
• B. Battery bank and shielded cables
• C. DC wiring only
• D. Inverter bank and transformer

Answer: (A)

When a PV system ties into the electrical grid, the items at the connection point to the utility are what define the interconnection. The interconnection equipment includes the devices that safely connect and disconnect the PV system from the grid, provide protection, and coordinate with the utility’s system. The utility meter is also part of this interface, measuring the energy that flows between the PV system and the grid for billing and net metering purposes. The other elements listed don’t fit this boundary. A battery bank is used for energy storage in off-grid or hybrid setups, not for the grid connection itself. Shielded cables or DC wiring pertain to internal wiring of the system, not the external interconnection with the utility.
