Reducing the cost of electricity, improving quality and efficiency, and multi-industry integration are the development trends of the modern photovoltaic industry. This places higher demands on the performance of photovoltaic products, including photovoltaic inverters. Although the inverter accounts for a small proportion of initial investment, its role as a bridge connecting the grid and photovoltaic power generation units cannot be ignored.
The inverter is the core equipment of the photovoltaic power plant. Through the power electronics inverter technology, the DC power generated by the PV modules is converted into AC power that can be integrated into the grid. In the field of photovoltaic inverters, the three major mainstream technologies, namely string, centralized, and distributed, are leading the way.
Among them, the compact string string inverter is most favored by medium and small photovoltaic power plants. Its application scenario is very extensive. It has played a key role in industrial and commercial distributed rooftops, household photovoltaic systems for household use, and village-level PV-powered poverty alleviation power stations.
The string type can occupy a place in the market, thanks to the following advantages: easy installation, wall-mounting does not occupy space, especially suitable for small and medium-sized distributed photovoltaic applications; flexible technology, up to 4 MPPT channels, components The access scheme is flexible, and it can be applied to the installation orientation of various components. The maximum efficiency of the tracking range is wide, and the power generation time is longer. The maintenance is simple, and the equipment maintenance is replaced by a complete machine, which does not require the maintenance of professional technicians.
For the needs of customers in industry and commerce, household and poverty alleviation industries, the new energy solutions and integrated energy service provider Kehua Hengsheng independently developed a series of photovoltaic grid-connected inverter series, which can provide customers with efficient power generation, safe and reliable, intelligent management The four major economic values ​​are good.
