Off Grid Solar Hybrid Inverter The Development Trend Jul 17, 2017

Off Grid Solar Hybrid Inverter The development trend

China's converter market is currently in a period of high growth, widely used in air conditioning, elevator, metallurgical and mechanical industries. According to statistics, in the past few years China's inverter market maintained a 12% growth rate of 15%, the rate has been far more than the level of GDP growth in recent years, and at least in the next five years maintained a more than 10% growth rate. Given that about 4-6% of the price is falling, the increase in capacity (power) in China's market is actually about 20%. At this rate of development and demand in the Chinese market, the market will be saturated and mature in at least 10 years. Therefore, China's converter market has broad development space.

Energy saving, consumption, top priority

"China's current energy problems are more of a bottleneck than a crisis," according to industry representatives during the two sessions. Energy tensions are relative, not absolute. China's energy shortage, structure and distribution are extremely unreasonable. Energy waste and environmental pollution caused by technological level and production capacity are becoming more and more problems. Therefore, rational development and use of energy requires a coordinated process.

Energy saving and energy consumption, frequency converter

Reducing energy consumption is not simply energy saving, it involves energy extraction, processing and downstream energy use.

This requires us to improve the efficiency of energy development, production and processing, and reduce waste. We should adopt advanced technology equipment and products to save energy, reduce consumption, water conservation and environmental protection, and upgrade or eliminate the outdated production capacity, technology and products that consume high and pollution. Among them, the automation enterprise opportunity is huge, the most direct is the inverter production enterprise. From the upstream oil, natural gas, coal mining, to energy transportation and power generation, to downstream petrochemical, steel, automobile production until the later water treatment, environmental protection, everything.

The original purpose of frequency converter is to control speed and apply to printing, elevator, textile, machine tool and production line. However, a considerable number of applications are aimed at energy conservation. Due to China's energy consumption power, energy efficiency is relatively low, while China's energy reserves are relatively poor, so the state vigorously advocated various energy-saving measures, and by the state economic and trade commission and the state planning commission in 2001 developed "save electricity management method", on the technology of frequency converter speed control. In the field of water pump and central air conditioning, the frequency converter can replace the traditional technology of limiting valve and backflow bypass to make full use of energy saving effect. In the industry of thermal power, metallurgy, mining and building materials, the economic value of the ac motor system with high voltage frequency conversion is being reflected.

Domestic companies are ready to go

In recent years, domestic variable frequency enterprises have mushroomed in the market demand of energy conservation and environmental protection, but few enterprises have been named in the quality of products. Speaking, according to the personage inside course of study is compared with the frequency conversion enterprises abroad, walk at the top of the technology of several domestic enterprises is of great competitive advantage, the domestic enterprise product design completely suitable for domestic users demand indicators, in performance quite inverter products, in price, a third of the product is higher than domestic products abroad, and foreign enterprises in the aspect of after-sales service is more expensive, most domestic enterprises has the disadvantage of insufficient funds, so can't big hair extension market, believe that as the user to further improve the energy conservation and environmental protection consciousness, after two or three years of its development, domestic enterprises will catch up with and surpass the overseas enterprise, occupy a larger share of the domestic market.

Market research shows that at present domestic belt fluctuates load, the motor with energy-saving potential has at least 180 million kilowatts in China. Therefore, the energy efficiency and consumption demand of energy intensity have provided a broader space for the application of inverter and brought more development opportunities for inverter enterprises
