Welcome to Shenzhen Dongshengyuan Electrical Equipment Co., Ltd.
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.
Main Features:
- Reserved installation space for a meter and collector;
- Visible window for the meter and sealed lead outlet (anti-tampering);
- Integrated design concept where the distribution section is completely isolated from the metering section, reducing electromagnetic interference;
- Optional self-resetting over-voltage and under-voltage protectors, as well as photovoltaic-specific reclosing circuit breakers, to meet the usage requirements and acceptance standards of different regions;
- The box cover requires a specialized key for opening, ensuring professional management;
- Options for powder-coated or stainless steel enclosures;
- Safe for outdoor installation;
- Customizable for special requirements and functions.
