Why does the inverter need heat dissipation

The solar inverter is a very important equipment of solar power system, the main role is to send out DC from PV modules into alternating current, in addition, the inverter also have the functions of detection component, power cable operation state, communication and external communication, system security and so on. In the standard NB32004-2013 of the photovoltaic industry, the inverter has more than 100 strict technical parameters, and each parameter is qualified to get the certificate. The state quality inspection administration will also checks on the protection of solar on grid inverterproducts every year, connecting contact current, solid insulation withstand voltage, rated output, conversion efficiency, harmonics and waveform distortion, power factor, DC component and AC output side / undervoltage protection 9 items were tested. A new inverter, from development to production, need more than two years, in addition to the under voltage protection function, inverter has many little-known high-tech, such as leakage current control, thermal design, electromagnetic compatibility, harmonic suppression, control efficiency and so on, need to invest a lot of manpower and material resources to development and testing.
Now is the winter, many people are worried about the inverter can withstand cold, actually there are few inverter failed because of cold weather. The most important problem of the inverter is the heat dissipation, by the report of world famous BCC survey, the reason of most of the current electronic products failure 55% is due to heat dissipation was not done well, the reliability of electronic devices the work is very sensitive to temperature, the temperature in 70-80 degrees every increase of 1 degrees, the reliability will decrease by 5%. High temperature will shorten the life of the inverter and reduce the reliability of the machine.

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...
