Photovoltaic Grid-Tie System Based on Deye String Inverter

As solar power becomes a dominant player in the renewable energy sector, the integration of photovoltaic (PV) systems with the grid and backup power sources is increasingly important. Deye string inverters provide an efficient and reliable solution for grid-tied solar systems, offering advanced features that enhance system stability and performance. This blog explores how Deye string inverters enable seamless operation in grid-tied applications and support backup power scenarios.

1. Frequency Droop Control Algorithm & VSG Application

One of the standout features of Deye string inverters is their ability to work alongside diesel generators when the grid is down. Through the frequency droop control algorithm and Virtual Synchronous Generator (VSG) application, these inverters ensure a stable power supply by mimicking the behavior of traditional synchronous generators.

Key benefits include:

• Uninterrupted Power Supply: When the grid is unavailable, Deye string inverters automatically synchronize with diesel generators, allowing continuous power delivery to the connected loads.

• Parallel Connection Support: Unlike conventional setups that require an external controller for multiple parallel connections, Deye string inverters can operate in parallel without additional hardware. This simplifies the system design and reduces installation costs.

• Improved Grid Stability: The VSG function enhances grid stability by enabling the inverter to respond dynamically to fluctuations in load and frequency.

2. Meter Applications

By setting a minimum output power for the diesel generator with a meter, system stability can be ensured.

Conclusion

Deye string inverters offer a smart and efficient solution for photovoltaic grid-tie systems, particularly in scenarios where backup power sources like diesel generators are required. With advanced features such as frequency droop control, VSG applications, and meter-based power regulation, these inverters ensure a seamless transition between grid power and alternative sources. For businesses and homeowners seeking a reliable and cost-effective solar energy solution, Deye string inverters stand out as a top choice.
