Pure Solar Telecom Power Systems — ONESUN Provides Complete Off-Grid Communication Energy Solutions

Publish Time: 2025-11-26

As today’s communication networks continue expanding—especially across remote mountains, deserts, rural areas, and temporary base-station sites—traditional grid electricity often becomes difficult to access. Ensuring stable power supply has therefore become a major challenge for many operators and telecom engineering teams. In these scenarios, a “pure solar + battery storage + smart inverter” photovoltaic power system is rapidly becoming a popular, efficient, and environmentally friendly solution. Among the global suppliers in this field, the internationally recognized brand ONESUN stands out as a provider worth paying attention to.

Founded in 2014, ONESUN is a manufacturer specializing in integrated systems combining solar PV, energy storage, and inverters. The company not only produces Li-ion batteries but also designs and manufactures its own inverters, BMS (Battery Management Systems), and PCBA units. This allows ONESUN to build a vertically integrated supply chain—from battery cells to inverters and complete system solutions.

From a technical standpoint, ONESUN uses Class-A LiFePO₄ batteries supplied by top-tier Chinese manufacturers, ensuring high safety and long service life.

Its inverters use core components from globally recognized brands (such as Infineon IGBT modules and Toshiba MOSFETs), ensuring system stability, durability, and strong compatibility with telecom power requirements.

Additionally, the company has strong production capacity, with an annual output exceeding 768 MW. Its products have been exported to more than 70 countries, with cumulative project deliveries surpassing 3 GW and a customer satisfaction rate of approximately 90%.

ONESUN’s Telecom / Base-Station Power Solutions

For telecom base stations, relay stations, or remote communication sites, ONESUN provides dedicated “telecom room backup power / solar + storage systems.”
According to their official product list, offerings such as the “Communication Rack Battery — 51.2V 200Ah” are designed specifically for telecom backup and primary power applications.

In locations without access to grid power, a full solar configuration can be deployed, consisting of PV panels + battery storage + inverter. During daylight, solar panels generate electricity and charge the batteries. At night or during cloudy periods, the batteries supply continuous power to ensure 24-hour operation of telecom equipment. This approach reduces grid extension costs, lowers maintenance requirements, and is ideal for remote, unmanned, or temporary deployments.

Moreover, ONESUN’s system architecture is optimized for telecom environments: BMS functionality, inverter compatibility, and overall system stability are enhanced to withstand harsh conditions such as temperature fluctuations, dust, vibration, or outdoor cabinet settings—making them well-suited for tower base stations and high-reliability telecommunications infrastructure.

ONESUN offers ready-made all-in-one energy storage systems and also supports free customized battery service. If standard models do not fit project requirements, customers can work directly with ONESUN’s engineering team to design a system tailored to specific power loads, environmental conditions, and equipment requirements.

Because pricing depends on system size, configuration, customization level, and destination, there is no universal public retail price listed on the website. The typical process is:
customer contacts ONESUN → requirement confirmation → official quotation → contract → shipment.

For any telecom site requiring a pure solar communications power system, you can contact ONESUN directly for a project-specific quotation and system layout drawings.

Compared with traditional grid power or diesel generators, ONESUN’s pure solar telecom power system offers several clear advantages:

1. Green and zero-emission, aligning with the telecom industry’s low-carbon development goals.
2. Low long-term operating cost—no fuel consumption and low battery replacement frequency.
3. High feasibility and reliability in remote or off-grid areas where conventional power is unavailable.

However, it’s important to note that solar telecom systems require careful initial planning—including accurate load evaluation, assessment of local sunlight conditions, proper sizing of batteries and inverters, and ensuring BMS reliability and protective measures.

Overall, ONESUN’s pure-solar telecom power system is a solution worth serious consideration for operators, tower companies, and communication network builders in remote or off-grid regions, offering long-term operational and economic benefits.
