The working environment of solar inverter

1.Solar power inverter requires high efficiency. Due to the high price of solar cells, in order to maximize the use of solar cells, improve system efficiency, we must try to improve the efficiency of the solar inverter.
2.Solar inverter requires high reliability. Solar power generation system is mainly used in remote areas, many power station unattended and no maintenance, which requires the inverter with a reasonable circuit structure, strict screening of components, and requires the solar system inverter with various protection functions, such as input DC reverse polarity protection, output short circuit protection, overheating protection, overload protection etc..
3.Solar inverter requires a wide range of DC input voltage. The solar battery terminal voltage varies with load and sunshine intensity, although the voltage of solar cell battery plays an important role, but because of the battery voltage fluctuate varies with the change of residual capacity and internal resistance of battery, especially when the battery aging, the change range of terminal voltage is very wide, such as 12V battery, the voltage can be the change in 10V ~ 16V, which requires the inverter must ensure the normal operation in a wide range of DC input voltage, and ensure the stability of output voltage.
4.In the middle and large capacity solar power system, the output of the inverter should be a sine wave with small distortion. This is because in the middle and large capacity system, if use square wave power supply, the output will contain many harmonic parts, which will produce additional losses. Many loads of the solar power system is a communication or instrumentation equipment, these devices have higher requirements on the quality of the power grid. In order to avoid the pollution of the power grid, the inverter output sine wave current is needed.

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...
