Reducing the cost per kilowatt-hour, improving quality and efficiency, and integrating with multiple industries are the development trends of the modern photovoltaic industry, which places higher demands on the performance of photovoltaic products, including photovoltaic inverters. Although inverters account for a small percentage of the initial investment, their role as a bridge connecting the power grid and photovoltaic power generation units cannot be underestimated.
Inverters are the core equipment of photovoltaic power plants. Through power electronic inverter technology, they convert the direct current generated by photovoltaic modules into alternating current that can be connected to the power grid. In the field of photovoltaic inverters, string inverters, centralized inverters, and distributed inverters are the three main technologies, each with its own strengths.
Among them, the compact string inverter is most favored by small and medium-sized photovoltaic power stations. Its application scenarios are very wide, playing a key role in industrial and commercial distributed rooftops, residential photovoltaic systems, and village-level photovoltaic poverty alleviation power stations.
String photovoltaic systems have secured a place in the market thanks to the following advantages: easy installation, wall-mounted installation saves space, making them particularly suitable for small and medium-sized distributed photovoltaic applications; flexible technology, with up to 4 MPPT channels, flexible module access schemes, and applicability to various module installation orientations; wide maximum efficiency tracking range and longer power generation time; and simple maintenance, with equipment repair using whole-unit replacement, eliminating the need for professional technicians.
To meet the needs of industrial, commercial, residential, and poverty alleviation customers, Kehua Hengsheng, a provider of new energy solutions and integrated energy services, has independently developed a series of string photovoltaic grid-connected inverters, which can provide customers with four major values: high-efficiency power generation, safety and reliability, intelligent management, and good economic performance.
