Focusing on energy saving and emission reduction, Huawei provides two power supply solutions: the diesel generator-battery hybrid solution and alternative energy solution, aiming to meet the power requirement in the regions where the mains supply is unavailable or unstable. In addition, the two solutions reduce the OPEX, and increase the return rate of investment.

D.G.-battery Hybrid Power Solution (Power 1000)
In this solution, the core control unit controls the diesel generator and the battery working in an alternative mode intelligently. The diesel generator charges the battery when providing the power supply to the site, as increasing its load capability. After the charging is finished, the battery starts to provide the power to the site, and the diesel generator stops. The alternative working mode between the diesel generator and the battery reduces the operation time and fuel consumption of the diesel generator. In addition, it reduces the cost of the diesel generator refueling and maintenance.
Alternative Energy Solution (Power 2000)
The alternative energy solutions consist of the solar power solution, solar-diesel generator hybrid power solution, solar-wind hybrid power solution, and solar-wind-diesel generator hybrid power solution. They are flexibly configured according to customers' needs and local climates. These solutions support various application scenarios, lower the TCO, and meet the requirements of energy saving and emission reduction. These solutions are applied in more than 1500 sites in over 30 countries and regions at present.
As a mature technology and environment-friendly power solution, it meets the requirements for convenient maintenance, high reliability, and little influence on the environment. Because of the reduction of power consumption and the cost of solar panels, the improvement of solar conversion efficiency, and using of Huawei MPPT controller, over 60% of the operation cost for a single site, and over 40% of the footprint requirement are reduced, compared with those in 2007. Large-scale application of the solution is mature.
According to different requirements, the solar power supply system developed by Huawei has various anti-theft strategies to enhance the anti-theft performance at the site.
The solar-wind hybrid power supply system uses two renewable green energies, namely solar energy and wind energy, to supply stable and reliable power to the site. The system provides the site with a reliable 24-hour power supply in both sunny days and rainy days by implementing the solar energy and wind energy, thus enhancing the system stability. This solution features with light maintenance, complementary resources, high reliability, and little influence on the environment.
The solar-diesel generator hybrid power solution provides the power to the site by complementing the solar energy and diesel generator. It eliminates the risk of the solar power solution caused by rainy days or the fluctuation of the sunshine duration in different period. Therefore, the solution is supplementary to the solar power solution. Meantime, the solar-diesel generator hybrid power solution aims to reduce the initial cost, and achieve the best investment return through optimized configuration of the diesel generator and the solar panel. For the site with the diesel generator, the solution is applied by using the previous diesel generator, thus greatly reducing the fuel and maintenance cost for the diesel generator.
