Product overview: In order to reduce the connection line between the photovoltaic grid-connected inverter and the grid-connected cabinet, facilitate maintenance and improve reliability, the general large-scale photovoltaic grid-connected power generation system needs to add a distribution box between the photovoltaic grid-connected inverter and the grid-connected cabinet. In order to improve the reliability and practicability of the system, the workers have installed AC lightning protection module, AC fuse and waterproof terminal in the AC distribution box. The protection grade of the industrial AC distribution box is IP65, with waterproof, moisture-proof, ash-proof, rust-proof and salt fog-proof functions, which can meet the requirements of outdoor installation. Functional features: 1. The cabinet body is made of hot-dip galvanized steel plate. The structure of the cabinet body is safe and reliable with sufficient mechanical strength. 2. Equipped with photovoltaic special circuit breaker, photovoltaic special lightning protector, photovoltaic special waterproof joint. 3. The wire of the box body adopts high-quality copper wires and high-quality copper bars to ensure safe and reliable connection. 4. The box body is compact in design and neatly arranged to meet the electrical design requirements. 5. AC box can be customized with rated voltage of 480V or 380V according to series inverters. 6. The lightning protector can be equipped with Class B or Class C lightning protection. 7. The AC box is equipped with multi-functional instruments, and the collected current and voltage, the status of circuit breaker and lightning protection device are sent to the background monitoring system through RS485 communication. The instruments have a rated voltage of 480V for power supply.
