PV Grid Connection Requirements Overview

Connecting a solar system to the grid requires compliance with local grid codes and technical standards. This guide covers the essential requirements for safe, compliant grid connection.

1. Anti-Islanding Protection

When the grid goes down, your PV system must stop supplying power immediately. This protects line workers. All grid-tied inverters have built-in anti-islanding protection.

2. Voltage and Frequency Ride-Through

Grid codes require your system to stay connected during minor voltage and frequency fluctuations. This helps stabilize the grid.

3. Power Factor Control

Most utilities require power factor between 0.95 lagging and 0.95 leading at the point of common coupling.

4. Protection Relays

Over/under voltage, over/under frequency, and earth fault protection are mandatory. The PV grid-connected cabinet houses all these protection devices.

5. Metering and Data

Your utility will install a bi-directional meter. Many grid codes also require remote monitoring and data logging.
