Distributed photovoltaic power generation system, also known as decentralized power generation or distributed power supply, refers to the deployment of smaller photovoltaic power generation systems at the user site or near the site to meet the needs of specific users and to support the economy of existing distribution networks. Run, or meet both requirements at the same time.
The basic equipment of the distributed photovoltaic power generation system includes photovoltaic cell modules, photovoltaic square array supports, DC combiner boxes, DC distribution cabinets, grid-connected inverters, and AC distribution cabinets, as well as power supply system monitoring devices and environmental monitoring. Device. The operating mode is that under the condition of solar radiation, the solar cell module array of the photovoltaic power generation system converts the output energy of the solar energy into the DC distribution cabinet through the DC convergence box and reverses the conversion from the grid-connected inverter to the alternating current supply. The building itself is loaded, excess or insufficient power is regulated by connecting the grid
Distributed photovoltaic generation definition
Photovoltaic power generation: According to the photovoltaic effect principle, solar photovoltaic cells are used to directly convert solar radiation energy into electrical energy. Photovoltaic power generation is currently the mainstream of solar power generation. Nowadays, people usually say that solar power generation mainly refers to photovoltaic power generation.
Distributed photovoltaic power generation refers to the photovoltaic power generation facilities that are constructed and operated near the user's site, and are characterized by user-side self-use, superfluous capacity with voltage levels below 35 dry volts, and balanced adjustment of the distribution network system; Features are: Spontaneous use, near consumption, Internet access, grid regulation.
Distributed photovoltaic grid-connected system advantages
1. The blue sky solar photovoltaic power generation system design, scientific and reasonable, beautiful and generous;
2. Can effectively use the vacant floor of the building to produce clean electricity;
3. It can not only be used for production, work and daily life, but also can be used to implement surplus electricity and grid sales;
4. The system runs fully automatically, is stable and reliable, has a long service life, and has a significant energy saving effect. The one-time investment has benefited for more than 20 years.

Duplex Stainless Steel Overview
Duplex Stainless Steels, also referred to as austenitic-ferritic stainless steels, are a family of grades with about equal proportions of ferrite and austenite. These steels have a duplex microstructure which contributes to their high strength and high resistance to stress corrosion cracking. Due to their high content of chromium, nitrogen and molybdenum, duplex steels offer good resistance to local and uniform corrosion. Duplex stainless steels have good weldability.
Today, modern duplex stainless steels can be divided into three groups:
Lean Duplex such as LDX2101
Standard Duplex such as 2205, the work-horse grade accounting for more than 80% of duplex usage
Super Duplex such as Ferralium 255 and Zeron 100 and LDX2507
Of the duplex grades, duplex 2205 is the most widely used. However, the super duplex steels like Zeron® 100 and LDX2507 are excellent for servicing severe corrosive environments, such as offshore and marine applications. Lean duplex 2101 is available as an economic alternative to 300 series stainless steels.
