In solar power systems, DC to AC inverters play a crucial role in converting the direct current (DC) generated by photovoltaic (PV) panels into usable alternating current (AC) electricity. This conversion enables the AC electricity to be fed into the electrical grid, making it suitable for powering homes, businesses, and other electrical devices.
String Inverters for ResidentialProjects
String inverters are commonly used in residential solar projects, including rooftop, carport, ground mount, and tracker installations. They offer reliable and efficient DC to AC conversion, ensuring optimal energy output from PV panels. One prominent brand that offers a range of string inverters is Sungrow.
Sungrow’s SG15/20RT string inverter is designed for residential use. It features a wider MPPT voltage range and built-in PID recovery function for higher yield. This inverter is compatible with bifacial modules and has smart IV curve scanning for efficient management. It also has safety features like quick arc fault circuit interrupter and Type II DC & AC SPD. The compact design with push-in connectors makes installation easy, and the over-the-air firmware updates ensure that the inverter is always up-to-date.
Central Inverters for Utility-Scale Applications
Central inverters, on the other hand, are specifically designed for utility-scale applications such as large buildings, industrial facilities, and vast field arrays. The SG3125HV-MV-30 is a central inverter for 1500 Vdc system MV transformer integrated, designed by Sungrow for utility-scale applications. It features advanced three-level technology with a maximum efficiency of 99% and effective cooling for full power operation at 50 ℃. It also has integrated zone monitoring and MV parameters monitoring function for online analysis and troubleshooting, modular design for easy maintenance, and a convenient external touch screen. The product is cost-effective due to its low transportation and installation costs, DC 1500V system, and integrated MV transformer, switchgear, and LV auxiliary power supply. It also has an optional Q at night function and complies with IEC 62271-202, IEC 62271-200, and IEC 60076 standards, with low/high voltage ride-through capability and active/reactive power control. The product is suitable for large-scale utility applications that require high efficiency and reliable performance.
Conclusion
DC to AC inverters play a vital role in solar power systems, enabling the conversion of DC electricity generated by PV panels into usable AC electricity. String inverters offered by Sungrow are ideal for residential and commercial projects, while their central inverters cater to utility-scale applications. With a wide range of products and a reputation for efficiency and reliability, Sungrow is a trusted brand for those seeking high-quality inverters for their solar power systems.
