Environmental adaptability of solar on grid inverter

Environmental adaptability refers to the ability of a product to achieve all its intended functions, performance and non-destructive ability under the action of various environments it may encounter in its life cycle prediction. It is an important quality characteristic. It can be seen that environmental adaptability has two elements, one is product and the other is environment. The same product has different environmental adaptability in different environments, and different products have different environmental adaptability in the same environment. Environmental adaptability is one of the quality characteristics of equipment. Once the product is finalized, the materials, components, structural composition and selected process have been solidified, and the environmental adaptability for the given environmental profile is fixed. It can be seen that environmental adaptability is the inherent quality characteristics of products, determined by design and manufacturing, and guaranteed by testing and management.

Generally speaking, the factors that affect product environmental adaptability are as follows.
1.Environmental adaptability of the selected materials and components.
2.The level of structural design includes thermal design, anti vibration, impact protection, corrosion prevention, PCB layout and other design levels.
3.The manufacturing level includes the technological level of structural parts, components, components and veneer protection.

Solar power generation system is usually directly exposed to the outdoor environment, often encounter high temperature, cold, humidity, wind and sand, rain, salt fog and other adverse weather conditions, solar on grid inverter as the key equipment of the whole solar power system, undertake the important role of current conversion, system communication, fault diagnosis and protection. Solar on grid inverter must be able to adapt to different operating environment, especially in harsh environment can still work stably.

Temperature challenges faced by PV grid-connected inverter mainly come from diurnal temperature difference, seasonal temperature difference, weather changes and self-heating. In many northern areas, the temperature is below – 20℃ in winter, over 40℃ in summer, big temperature difference between day and night, big seasonal temperature difference, inconsistent temperature change between the inverter shell and the internal temperature, easy to form temperature difference in the internal cavity, frequent temperature changes, product design, component selection are a serious challenge. The inverter running in wet environment such as coastal and beach will also face the risk of corrosion.

Correct selection of backup time for UPS

图片
UPS backup time is generally a problem concerned by customer in the purchase process. Usually most people prefer to choose the  UPS  which power backup the longer the better, in fact, this is not correct. We must firstly clear that the seller will usually have standard type UPS and long-acting UPS. Standard type UPS with built-in battery, after a power interruption can supply power to the load equipment in general for a few minutes to tens of minutes, of course, the length of time depends on the load. Long acting UPS can not only meet the power requirement of load, but also meet the requirements of customers and work types and so on, so the long-term UPS is usually equipped with an external battery pack. If the client is not particularly strict to the work condition of the load, and the power of the load is not particularly large, usually with standard type UPS would be enough. Because the choice of long backup time UPS is bound to increase the number of battery groups an...

126th Canton Fair

图片
On Oct 15th 2019, as one of the most important trade promotion platforms for Chinese enterprises to expand the global market, Canton Fair in Guangzhou focused on highlighting innovation driven, and “independent brand” became a high-frequency word of Canton Fair. Xu Bing, a spokesman for the Canton Fair and deputy director of the China Foreign Trade Center, said that the domestic and foreign environment faced by China’s foreign trade development this year is more complex and uncertain. The majority of exhibitors accelerated quality improvement and innovation, and continued to make efforts in technology research and development, product innovation, brand cultivation, etc., with high technology, high quality, high added value and independent brand products emerging. Many independent innovative R & D products are welcomed by the market. At the same time, purchasers are less sensitive to price and pay more attention to the technology, brand, quality and service of products. In ...

How to maximize the efficiency of your UPS

图片
1.Use of AC voltage regulator After using  UPS power supply , there is no need to add AC voltage regulator. If it must be added, it should be added to the front level of UPS, that is, the mains power first passes through the AC voltage regulator, then through the ups, and then to the load. 2.Battery balanced charging skills At present, valve regulated lead-acid battery (VRLA) used in many ups power supply is called maintenance free battery from the beginning, which gives users a misunderstanding that it seems that this battery is durable and does not need maintenance at all. Under this kind of misleading, many users have not carried out maintenance and management since they installed the battery. When the battery in UPS power supply meets the following conditions, the battery shall be charged evenly: when the terminal voltage is lower than the specified calibration voltage due to excessive discharge. For 12 V small sealed lead-acid batteries, the discharge calibration voltage is...
