HJDXH Series of Photovoltaic - Utility Hybrid Power Supply System of Huijue: A Reliable Guarantee for Power Supply of Communication Base Stations

I. Product Overview

The HJDXH series of photovoltaic – utility hybrid power supply system of Huijue is a control and management system that uses a mixture of solar energy and utility power to supply power to communication equipment rooms. Its core function is to convert the power from solar panel arrays, utility power, or diesel – generator sets into stable and reliable low – voltage direct current for the use of communication equipment.

II. Working Principle

1. Energy Coordination and Storage

The system can maximize the utilization of solar energy by skillfully coordinating various power inputs. When there is sufficient sunlight, the solar panel arrays generate electricity, and the system will store the surplus electricity in the storage batteries. In this way, when there is insufficient sunlight, the electricity in the storage batteries can continue to supply power to the communication equipment.

When there is an input at the utility power input interface and the solar output is insufficient, the system will automatically switch to use the utility power to maintain the load operation and charge the battery pack at the same time. This flexible energy – switching mechanism ensures the continuity of power supply.

Even in the extreme case of long – term rainy weather and no available utility power, the storage battery pack can discharge to supply power to the load, ensuring the normal operation of the communication equipment.

2. Wide Applicability

The HJDXH series of photovoltaic – utility hybrid power supply system of Huijue is applicable to various indoor and outdoor communication base stations and distributed base stations. Whether it is an indoor communication equipment room in the city or an outdoor base station in a remote mountainous area, this product can play its role as a reliable power supply guarantee.

III. Product Features

1. Multi – energy Solutions

This product can flexibly form different forms of complementary power supply systems with solar energy, utility power, and diesel – generators according to different site environments. This multi – energy combination method can meet the power supply requirements of communication base stations under different geographical environments and climate conditions.

2. Energy – saving Management Mode

The system adopts an energy – saving management mode that gives priority to using solar energy for power supply to the greatest extent, with utility power (or diesel – generators) as supplementary energy and battery packs as backup energy. Through this mode, not only can green energy be fully utilized, reducing dependence on utility power and diesel – generators, but also operating costs and carbon emissions can be reduced.

3. Battery Management Function

The photovoltaic – utility hybrid power supply system of Huijue can ensure the normal battery charge – discharge management and protection functions of the system. This helps to extend the service life of the batteries and ensure that the batteries can supply power reliably at critical moments.

4. Modular Design

The system adopts a modular design, and the system capacity can be flexibly configured. This design makes the product more convenient and faster for installation and capacity expansion, and can be flexibly adjusted according to the actual electricity demand.

5. MPPT Function

The system has the MPPT function with a maximum power tracking accuracy greater than 99.5% and a solar energy system conversion efficiency greater than 95%. This feature can ensure that the solar panel arrays can convert electrical energy efficiently under different lighting conditions and improve the utilization rate of solar energy.

6. Simple Maintenance

The system has front – side operation, and all modules can be hot – swapped and replaced online. This means that when performing system maintenance or module replacement, no complicated operations and long – term shutdowns are required, greatly improving maintenance efficiency and reducing the impact on communication services.

7. Monitoring and Control Function

The HJDXH series of photovoltaic – utility hybrid power supply system of Huijue has local/remote real – time monitoring system functions and is equipped with RS – 232/RS – 485 interfaces. Through these interfaces and monitoring functions, operation and maintenance personnel can conveniently monitor the running status of the system in real – time and carry out remote control, and timely discover and solve potential problems.

The HJDXH series of photovoltaic – utility hybrid power supply system of Huijue provides comprehensive guarantee for the power supply of communication base stations with its advanced technology, flexible energy management, and reliable performance, and is an ideal choice for power supply solutions of modern communication infrastructure.
