By optimizing performance, the inverter continually enhances energy output, ensuring that users derive maximum benefit from their photovoltaic installations.

INTERCONNECTIVITY WITH THE ELECTRICAL GRID

Photovoltaic systems often operate in conjunction with the electrical grid, which allows for greater flexibility and reliability. When a photovoltaic installation produces more energy than is consumed, the excess can be sent back to the grid, often generating credits for the energy supplier. This arrangement is known as net metering and can substantially offset energy costs over time.

During periods of low solar generation, such as at night or on cloudy days, the system can draw energy from the grid, ensuring continuous power supply. This electrifying interplay between renewable energy sources and traditional grid systems paints a promising picture for the future of energy consumption, demonstrating how solar power can work in harmony with existing infrastructure.
