Necessity of circuit breakers in photovoltaic systems   Circuit breaker is one of the indispensable components in the photovoltaic system, two main functions:    1: Electrical isolation function, used to cut off the electrical connection between photovoltaic modules, inverters, power distribution cabinets and the grid during installation and maintenance, to provide operato...

  In recent years, the technology of the photovoltaic industry has developed faster and faster, the power of a single module has become larger and larger, and the current of the string has become larger and larger,  the current of high-power modules has reached more than 17A. Using high-power components and reasonable matching can reduce the initial investment cost and kWh cost of the sy...

At 10:40 am on November 3, 2022, there was a "click" sound in the 10kV switch station of Huaneng Yueyang Leigutai Photovoltaic Power Station, and Anhui Jinli Photovoltaic Intelligent Energy Saving System was officially put into use in the power station, helping the power station's energy saving with our surge protective device and other products. Questions about friends in the circle: 1. Why do ph...

As photovoltaic (PV) systems become more widespread, ensuring their safety and reliability is essential, especially in preventing lightning and surge interference. Low Voltage Surge Protection Device (SPD) play a critical role in PV systems by reducing the risk of equipment damage. Here are some important considerations for applying SPD in PV systems. Ⅰ. Selection of SPD PV systems have relatively...
