  1 Overview

  The intelligent photovoltaic lightning protection DC cabinet is a function cabinet that summarizes, monitors and protects the DC power after the convergence of the photovoltaic combiner box (generally refers to the electric cabinet that summarizes the DC load), and the DC lightning protection cabinet can aggregate the multiple DC inputs into one current output. Each circuit has protection devices (circuit breakers, fuses, etc.), anti-reverse diodes, etc., and can monitor each voltage and current, and can realize remote communication.

  2, product features

  High-performance components and intelligent design. It has the advantages of high cost performance, beautiful appearance, convenient installation and use. It can monitor multiple current, voltage, power and switch status, and communicate with the monitoring system through RS485 communication interface to realize intelligent management of DC power distribution cabinet. Modular design, components adopt international or domestic famous brands, with excellent performance, safe and reliable. The internal wiring is reasonable and beautiful; the lightning protection grounding meets the technical requirements of lightning protection specifications. High breaking capacity, good thermal stability, flexible and convenient combination of electrical solutions, and practicality, can be customized according to customer needs.

  3. Implementation standards

  GB50254 "Code for construction and acceptance of low-voltage electrical installations for electrical installations"

  GB4208-2008 "Shell protection grade (IP code)"
