Since 2019, China has accelerated the construction of 5G infrastructure in all aspects. As of the end of July this year, the total number of 5G base stations reached 3.055 million, accounting for 26.9% of the total mobile base stations; China's 5G mobile phone users reached 695 million households, accounting for 40.6% of mobile phone users, an increase of 7.3 percentage points from the end of the previous year. Overall, the development of China's 5G base stations is promising, with ample future market space. Meanwhile, in the current thriving development of 5G, energy consumption is equally significant. Both Huawei and ZTE have previously released power consumption data for 5G devices, resulting in approximately three times the power consumption of 4G devices. According to statistics, the annual power consumption of a 5G base station is 37,500 kWh. Calculated at the current average price of 0.8 yuan/kWh for supplied electricity, the annual electricity cost for a 5G base station amounts to 30,000 yuan.

To ensure uninterrupted communication services, telecommunications base stations require 24/7 continuous and stable power supply. However, due to the instability of the power grid or even sudden power outages, communication services of telecommunication base stations may be interrupted. Therefore, the base stations need an additional power supply system as a backup power source. When the power grid fails, it can be promptly switched to power the entire system, ensuring the normal operation of telecommunication base stations. With the gradual development of "solar storage charging," the concept of "5G base station + photovoltaic" has been proposed. Compared to traditional solutions, the combination of solar storage charging and base stations not only enables flexible adjustment during peak and off-peak electricity consumption but also aligns with the country's ecological civilization construction requirements of "carbon neutrality and peak carbon emissions," thereby achieving low-carbon operations.

The Honeybee700 photovoltaic optimizer is the latest addition to the EnergyEase Honeybee series of products, specifically designed for solar storage charging systems for telecommunications base stations. It aims to solve component mismatch issues caused by shadow obstruction, inconsistent orientation, component aging, and reduce power loss and enhance safety.

Unlike other Honeybee series serial optimizers, the Honeybee700 employs innovative boosting optimization technology, allowing parallel connection with photovoltaic modules on the DC bus to achieve maximum power point tracking for each module, thereby improving the overall system's power generation. Additionally, the Honeybee700 photovoltaic optimizer features rapid shutdown functionality, which cuts off the optimizer's output in case of abnormal conditions such as overvoltage, overcurrent, overheating, or reverse current, ensuring the safety of the photovoltaic system. Furthermore, it supports component-level monitoring and fault diagnosis. Through wired or wireless communication interfaces, it provides real-time feedback on the working status and parameters of each component to the monitoring system, enabling users to remotely control and manage them using a computer or smartphone.

In addition to base station projects, the Honeybee700 is also suitable for other grid-connected or off-grid photovoltaic projects with energy storage batteries. Its lifespan of up to 25 years and reliability help reduce costs and increase efficiency in photovoltaic systems, effectively improve power generation efficiency and safety, reduce operational costs and maintenance difficulties, ultimately achieving green environmental protection and carbon peak and carbon neutrality.
