Adding to the green trend: How one-to-eight high-power micro-inverters can help the traditional textile industry reduce costs and increase efficiency

Traditional textile enterprises have the characteristics of large electricity consumption and high energy consumption. Therefore, under the background of "dual carbon goals", it is urgent to reduce their carbon emission intensity and form efficient and green production methods. The combination of photovoltaics and traditional textile industry provides an effective way for its green transformation and development and achieving cost reduction and efficiency improvement.

Just recently, a large textile factory in Jiaxing, Zhejiang installed a photovoltaic power station on its roof, with a total capacity of 1.99MW. The project fully adopted the QT2D micro inverter of APEC Technology with an output power of 3520W, and was put into use in a mode of self-generation and self-use, with surplus power connected to the grid.

After the system was put into operation, it not only met the company's daily electricity needs, but also reduced its energy consumption and electricity expenditure, helping the company to obtain obvious green and low-carbon benefits. The construction of the photovoltaic power station has injected new color and new momentum into this traditional textile company, and also played a demonstration and leading role in the implementation of the "dual carbon goals" by other local companies.

Extreme safety, careful protection

It is reported that the factory mainly produces chemical fiber fabrics, and the entire factory area pays special attention to fire safety, especially the workshops and factories. There are a large number of machines and equipment in the factory, and the load density is high. Therefore, at the beginning of the project selection and design, the owner made multiple assessments on the safety of the system and finally selected the QT2D micro inverter of AP Energy Technology.

Different from string inverter systems, QT2D adopts a low-voltage design. There is no DC high voltage when the system is running, which can eliminate the "high-voltage DC arcing fire risk" and "rescue risk", effectively avoid the occurrence of fire, ensure the ultimate safety of the DC end of the power station, and "escort" the safety of the factory building.

Reduce costs and increase efficiency, empower zero carbon

As a textile factory of considerable size in the local area, the factory has multiple production workshops and a large number of machines and equipment, and its electricity consumption is very huge, belonging to the industry and commerce with high load density. The owner was suffering from the actual electricity consumption situation and decided to install a photovoltaic system to solve the huge electricity consumption problem, and at the same time, it can also better help the enterprise reduce energy consumption and achieve green and low-carbon transformation and development.

Since the system was put into operation, the micro inverter QT2D has relied on its powerful maximum power point tracking (MPPT) function to effectively overcome the "short board effect", without fear of shadow obstruction, and greatly reduce power generation losses. In addition, compared with the single-phase grid-connected system, QT2D, as a three-phase intelligent micro inverter, can continuously output three-phase balanced AC power, further reducing system costs and improving power quality.

Intelligent operation and maintenance, one-stop service

As can be seen from the figure, the factory has a large roof area and many factory buildings. Its photovoltaic modules are distributed on multiple roofs, and the number is huge, which is a huge challenge for system operation and maintenance personnel. In the traditional string inverter system, once the equipment fails, the operation and maintenance personnel need to check each module one by one to finally determine the fault location, which is time-consuming, labor-intensive, and inefficient.

It is worth mentioning that the micro inverter QT2D comes with a digital intelligent operation and maintenance system. Through the APpower Technology EMA intelligent operation and maintenance platform, we can view the power generation, location and other information of the components. When the equipment fails, the user clicks on the problem component in the system to view the component's serial number and other location information, clearly find the "problem component", and achieve precise positioning in one step. It can even remotely diagnose power station faults without the need for on-site operation and maintenance, greatly saving operation and maintenance costs.

Technology empowers and makes zero-carbon life visible. AP Energy Technology has been committed to the research and development and innovation of MLPE technology, insisting on using the power of technology to promote the green and low-carbon development of society, and using safer, more efficient and intelligent products to help the low-carbon development of industry and commerce, so that more sunshine can gather the tremendous power to promote social development.
