TBEA Xinjiang Sunoasis Co., Ltd. products

PV array combiner box is mainly applied in medium and large scale surface power station, as the firstly combine device, it is used for the output power of strings combination, DC line protection and parameters monitoring, etc. The product provide reliable guarantee for power station with the characteristic with optimized structural design, strict components selection and reliable fault warning function.

It is mainly used for medium and large-scale power station as secondary return equipment of PV power station, which is in charge of connecting the DC cables from combiner box to grid-connected inverter after combination. The optimized heat flow design, convenient maintenance and design prior modulization, variety configuration selection as well as flexible interface design provide the powerful electric power auxiliary product for user.

TBEA central inverters ranging from 100KW to 1250KW are specifically designed for large scale solar power plant. The most advanced technology and excellent workmanship are integrated: advanced three phase full bridge topology structure, advanced dual LCL filter patent technology to realize lower power loss and to enhance the conversion efficiency as much as 98.7%. High efficiency, proven components, compact and modular design and a host of life cycle service ensure TBEA central inverters provide a high return on investment.

1250kW non-isolated type PV grid-connected inverter is a significant research result of NATIONAL 863 PROJECT undertaken by us. The successful research and applying of various technical development patents for product marks China has reached international advanced level in the field of large-scale centralized grid-connected inverter technology, but also represents we have been in the leading rank of international excellent inverter supplier.

The isolation type grid-connected inverters are with protection degree IP54, which can be applied in rainy and dusty outdoor environment. The industrial grade product design idea and the advanced full-bridge topological structure guarantee the inverter reliably operates with low loss and high performance. The advanced PR control technology ensures the output power with high quality and the on-grid current THDi

As the transition equipment of photovoltaic board and inverter, convergence box and DC power distribution cabinet achieve current convergence, and can achieve the multi-level isolation protection of high-power inverter system, easy maintenance, and other functions. Monitoring platform has a friendly man-machine interface and supports multiple languages, with the features of powerful cloud platform support, real-time data visualization, and rich graphical display.

Advanced topological structure, excellent AC output filtering design, efficient MPPT strategy, SVPWM technology with the minimum switching loss, perfect protection function, excellent cooling capacity, high product efficiency, super-strong product reliability, perfect anti-PID attenuation strategy, reliable islanding protection, excellent power quality, good power grid access, and the certification of CQC new energy standards.

Higher reliability (non-derating operation below less elevation 2000m), lower loss (intelligent start and stop), more excellent performance (excellent resonance suppression and harmonic compensation function, and reliable power grid fault ride-through capability), smaller floor area (floor space reduces by more than 30%), lower system cost (system integrated design and modular maintenance).

Have polycrystalline silicon chip, monocrystalline silicon chip, polycrystalline square rod, and monocrystalline quasi- square rod; monocrystalline product efficiency is more than 19.8%, polycrystalline product conversion efficiency is more than 18.5%.

It is a form of monatomic silicon, with gray and metallic luster. Density: 2.32-2.34; melting point: 1410 ?; boiling point: 2355 °C. It is soluble in the mixed acid of hydrofluoric acid and nitric acid, but does not dissolve in water, nitric acid and hydrochloric acid. Its hardness is between germanium and quartz; it is brittle at room temperature, and easy to break at the time of cutting. When it is heated to above 800 ? , it becomes ductile, and shows obvious deformation at 1300 ?. It is not active at room temperature, but reacts with oxygen, nitrogen, and sulfur at high temperatures. In melting state at high temperatures, it has large chemical activity, and can react with almost any materials.
