What are the advantages of leading string photovoltaic inverters?

Reducing the cost of electricity per kilowatt-hour, improving quality and efficiency, and multi-industry integration are the development trends of the modern photovoltaic industry, which puts forward higher requirements for 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 underestimated.




Inverter is the core equipment of photovoltaic power station. Through power electronic inverter technology, the direct current generated by photovoltaic modules is converted into alternating current that can be integrated into the power grid. In the field of photovoltaic inverters, the three mainstream technologies of string type, centralized type and distributed type are leading the way.




Among them, the compact string inverter is most favored by small and medium-sized photovoltaic power plants. Its application scenarios are very wide, and it plays a key role in industrial and commercial distributed roofs, household photovoltaic systems, and village-level photovoltaic poverty alleviation power stations.




The string type can occupy a place in the market thanks to the following advantages: easy installation, wall-mounted type does not occupy space, especially suitable for small and medium-sized distributed photovoltaic application scenarios; flexible technology, up to 4 MPPT channels, modules The access scheme is flexible and applicable to the installation orientation of various components; the maximum efficiency tracking range is wide, and the power generation time is longer; the maintenance is simple, and the equipment maintenance is replaced by the whole machine without the maintenance of professional technicians.


In response to the needs of customers in the industrial and commercial, household, and poverty alleviation industries, SAFESAVE, a new energy solution and integrated energy service provider, independently developed a series of string photovoltaic grid-connected inverters, which can provide customers with efficient power generation, safety and reliability, intelligent management, and economy Four values of good sex.
