Product Description
Product Description
Integrated control system for wind, solar, and energy storage
A subsidiary of Chengming Metal Technology (Shandong) Co., Ltd. is a national high-tech enterprise focused on the development and utilization of new energy. The new energy development investment platform, Sunshine New Energy, focuses on the fields of photovoltaic, wind power, wind and solar energy storage, hydrogen charging, and multi energy integration, providing comprehensive solutions covering the entire lifecycle of new energy development, including system research and development, development investment, design and construction, and operation management. It is the world's largest developer of photovoltaic power stations.
As a leader in the field of new energy system technology, the company was one of the earliest to establish a new energy system technology research and development center in the industry, creating a unique PowMart smart energy solution group, constructing three core technology systems of "efficient power generation, system integration, and full life cycle optimization of power stations", leading the formulation of multiple industry standards, and possessing strong independent research and innovation capabilities.
We are a leading one-stop solution provider for distributed photovoltaic power station systems in China, dedicated to professional production factories in the research and development, production, and testing of photovoltaic module products. And it is a comprehensive service provider that integrates research and development of new energy products, investment in power stations, production, sales, design, installation, grid connection, and operation and maintenance, from photovoltaic products to intelligent solutions. It is the first one-stop centralized procurement and operation center for photovoltaic power stations. The company has multiple TUV certified intelligent automated photovoltaic module production lines.
This includes suppliers of photovoltaic module materials (Longi, JA, Jinko, Tongwei, Huawei, Sunshine, etc.), production equipment manufacturers, and terminal sales service providers, covering countries such as Southeast Asia, Europe and America, South America, and Africa. With the joint participation of professional elites and sectors, the entire industry forms complementarity, multi chain collaboration, highly concentrated industrial chains, and rapidly soaring industrial scale and quality, constantly innovating and leading industry progress.
Environment condition1.Temperature of ambient air: -5°C~+40°C; The average daily temperature shall not be higher than +35°C. In case of excess, the capacity shall be reduced according to the actual situation.
2.Altitude: ≤ 2000m.
3.relative humidity: the maximum temperature of +40°C is not more than 50%, at a lower temperature allowed to have a large relative humidity: such as +20°C is 90%, should take into account the temperature changes may occasionally produce the impact of condensation. 4.The mounting incline shall not exceed 5. and the whole group of cabinets is relatively flat (in line with GBJ232-82 standard). 5.Switchgear should be installed in places free from severe vibration and shock and not enough to cause undue corrosion of electrical components.
