The centralized grid-connected inverter system has no redundancy ability. If it stops because of a fault, the entire system will stop power generation. The string inverter is suitable for small and medium-sized rooftop photovoltaic power generation systems and small ground power stations.
Inverter scheme comparison Central inverter: The power is between 100kW and 2500kW. With the development of power electronics technology, the string inverter is having an increasingly bigger market, and the central inverters below 500KW have already basically been eliminated from the market. The power device adopts high-current IGBT.
Power Electronics is a leading provider of central inverters for large solar projects. Their HEC V1000, HEM, and HEMK series are designed for utility-scale installations, offering robust and efficient performance. Power ratings up to 5 MW per inverter. Advanced MPPT technology for optimized energy harvest.
The most common types of solar inverters are string and central inverters, used as power conversion systems for grid-tie solar applications.
In the centralized grid-tied inverter system, the component square array reaches the power inverter through two convergences, and the maximum power tracking function (MPPT) of the inverter cannot monitor the operation of each component, so it is unable to make each component in the best working condition.
The top central inverter manufacturers, including Sungrow, GE Renewable Energy, Power Electronics, and SMA, offer advanced technologies such as MPPT, grid voltage regulation, and remote monitoring to maximize energy yield and ensure grid stability.
