Darui Electric recommends
Photovoltaic DC Control Cabinet adopts high-performance components and intelligent design. It has many advantages such as high performance-price ratio, beautiful appearance, and easy installation and use. It can detect each circuit's current, voltage, lightning protection status, and switch status. Through the intelligent instrument's large-screen LCD display of voltage, current, power, etc., it communicates with the monitoring system via RS485 communication interface to realize intelligent management of the DC distribution cabinet.

Modular design, using high-performance Hall sensors for acquisition;

Uses a large-screen LCD display intelligent instrument, which can collect up to 16 channels of current and output voltage. The LCD displays voltage, current, power, lightning protection status, switch status and other information. It has a standard RS485 digital communication interface to connect with the monitoring system;

The surge protector N+1 adopts internationally or domestically renowned products (e.g., DEHN, PHEONIX, CITEL).

The anti-reverse diode uses modular rectifier diodes, low power consumption, stable performance.

Internal wiring is reasonable, layout is beautiful, and internal connections use copper busbars;

Lightning protection grounding meets the technical requirements of lightning protection specifications.

The photovoltaic AC control cabinet is designed according to the grid-connected power generation unit. It needs to be equipped with an AC lightning protection distribution cabinet, mainly to connect the AC cable output from the inverter, then connect to the grid through a circuit breaker to supply power to electrical appliances. Convenient operation and maintenance. This series of distribution cabinet devices is suitable for low-voltage distribution systems with AC 50Hz rated voltage up to 690V and maximum rated current up to 3150A. As control equipment for various power generation, transmission, distribution, energy conversion, and energy consumption, it is widely used in new energy power systems, petrochemical, industrial and mining enterprises, public utilities, municipal engineering, commercial buildings and other low-voltage distribution systems. It can fully meet various application requirements in the market.
