Overview:
This product is primarily used in residential photovoltaic (PV) distributed grid-connected power generation systems and small commercial PV power generation systems. It is installed between the grid-tied inverter and the power grid, offering a range of protections including anti-islanding protection, under-voltage and over-voltage detection, automatic closing upon voltage restoration, tripping upon voltage loss, grid low-voltage and over-voltage protection, lightning protection for input, system overcurrent protection, and grid isolation. Additionally, it features accurate energy metering, transmission, and intelligent operation control, making it an essential component in household grid-tied power generation systems. The product is certified according to industry standards, including CCC certification and CE certification.
