Photovoltaic AC grid-connected cabinets, grid-connected boxes and photovoltaic combiner boxes are suitable for distributed photovoltaic power generation. Installed between the AC output terminal of the inverter and the mains grid connection point, they provide overcurrent protection, short circuit protection, lightning protection, overvoltage protection, undervoltage protection and leakage protection for the line. During maintenance, disconnect the knife switch and there is an obvious visible breakpoint. The cabinet is made of cold-rolled steel plate, with a safe and reliable structure and sufficient mechanical strength to ensure that there is no shaking or deformation of the components after installation and during operation. The protection level is IP30 or IP54, which meets the requirements of indoor or outdoor installation. It is equipped with circuit breakers, photovoltaic automatic reclosing circuit breakers or frame circuit breakers, lightning arresters and knife switches. It has long delay, short delay and instantaneous three-stage protection, lightning protection, overvoltage protection, undervoltage protection and leakage protection. When the mains power is off, the photovoltaic automatic reclosing circuit breaker in the grid-connected cabinet will automatically disconnect, when the mains power is restored, the photovoltaic automatic reclosing circuit breaker in the grid-connected cabinet will automatically close.
Photovoltaic grid-connected cabinets are a vital component of photovoltaic power generation systems. They undertake the important mission of integrating photovoltaic power into the power grid safely, stably and efficiently.
Advanced power conversion technology
The high-performance inverter can accurately and quickly convert the direct current generated by the photovoltaic array into alternating current with the same frequency, phase and amplitude as the power grid. Ensure high power conversion efficiency and low loss, and maximize the power generation efficiency of the photovoltaic system.
Multiple safety protection mechanisms
Equipped with complete protection devices, including overvoltage protection, undervoltage protection, overcurrent protection, short circuit protection, island protection, etc. Once an abnormality is detected in the power grid or photovoltaic system, the connection can be quickly cut off to ensure the safety of equipment and personnel, while avoiding adverse effects on the power grid.
Accurate power quality control
The built-in power quality monitoring and governance module can effectively suppress harmonics, improve power factor, ensure that the output power meets the strict quality standards of the power grid, reduce interference to the power grid, and improve the stability and reliability of the power grid.
Intelligent monitoring and remote communication
It has an intelligent monitoring system that collects and displays various operating parameters in real time, such as voltage, current, power, power generation, etc. Through the remote communication function, users can obtain the operating status information of the equipment through mobile phones or computers anytime and anywhere, and perform remote control and parameter adjustment.
