How many advantages do leading string photovoltaic inverters have?

Reducing the cost per kilowatt-hour, improving quality and efficiency, and integrating multiple industries are the development trends of the modern photovoltaic industry, which puts higher requirements on the performance of photovoltaic products including photovoltaic inverters. Although the inverter accounts for a small proportion of the initial investment, its role as a bridge connecting the power grid and the photovoltaic power generation unit cannot be underestimated.

The inverter is the core equipment of a photovoltaic power station. It uses power electronic inversion technology to 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, the three major mainstream technologies, string type, centralized type, and distributed type, are leading the way.

Among them, the compact string inverter is the most popular among small and medium-sized photovoltaic power stations. It has a wide range of application scenarios and plays a key role in industrial and commercial distributed rooftops, household photovoltaic systems, and village-level photovoltaic poverty alleviation power stations.

The string type has been able to occupy a place in the market due to the following advantages: easy installation, wall-mounted type does not take up space, and is particularly suitable for small and medium-sized distributed photovoltaic application scenarios; flexible technology, up to 4 MPPT channels, flexible component access solutions, and suitable for various component installation orientations; wide maximum efficiency tracking range and longer power generation time; simple maintenance, equipment maintenance uses complete machine replacement, and no professional technicians are required for maintenance.

In response to the needs of customers in the industrial, commercial, household, and poverty alleviation sectors, Kehua Hengsheng, a new energy solution and integrated energy service provider, independently developed a series of string photovoltaic grid-connected inverters to provide customers with four major values: efficient power generation, safety and reliability, intelligent management, and good economy.
