Solar hybrid grid tie inverter development prospects

From the perspective of photovoltaic development, the grid connected system installed capacity will occupy 90% of the market, the establishment of large power plants, rooftop solar energy applications is the main direction of development of photovoltaic industry. But with the future power generation costs reaching the level of conventional hydropower and thermal power costs, the proportion of off grid applications will increase. At present, the hybrid on grid inverter is the focus of development for all manufacturers, and its technical indicators represent the level of solar inverter technology.
However, since 2007, the selection of hybrid grid tie inverter installed in foreign grid connected soalr power generation system became more and more inclined to miniaturization, intelligent, modular development, the use of small soalr hybrid on grid inverter has become the development trend of soalr grid. The reason is the rise of large-scale foreign PV systems market, from small household power plant construction to use hundreds thousand KW class power station has been more common; in the grid connected power generation, cost control, security, reliability and other aspects of foreign countries have accumulated rich experience, and established a detailed and reliable grid connected power generation database.
In addition, the market demand for solar off grid inverters has also increased. Off grid solar power generation system is composed of solar controller, the management of charging and discharging the battery, and provide power to the DC load or the hybrid on grid inverter provides a new power supply power to the AC load, is widely used in the harsh environment of the plateau Island, Remote mountainous area and field operation, but also can be used as a telecom station, advertising light boxes, lamps and other power supply.
Off grid solar system will be widely promoted in the process of rural electrification, so the market demand of off grid inverter is expanding accordingly. By 2020, the global system will be 20% of the total installed capacity, and will reach 30% by 2030.

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...
