High-Efficiency 40-50kW Solar Inverter Products Description
The SUN-40/45/50K-G04 series three-phase grid-tied inverters are designed for large-scale solar applications, offering exceptional efficiency and reliable performance. With a maximum efficiency of up to 98.7%, this inverter series ensures optimal energy conversion, making it ideal for commercial and industrial solar systems.
The inverter supports up to 4 MPPT trackers, a wide MPPT voltage range (200V to 1000V), and includes intelligent monitoring options (GPRS/Wi-Fi/Bluetooth/4G) for real-time system performance tracking. With advanced protection features like anti-PID, overvoltage protection, and overcurrent protection, the inverter ensures the longevity and reliability of your solar system.
What is the function of a on grid inverter?
Simply put, one of the most important functions of a grid tied inverter is to allow users to draw power from the public grid when there is a power shortage, and sell excess power to the grid when there is sufficient power.
