How to choose the inverter for cold weather to ensure normal operation of PV power station

Low temperature will bring changes in physical properties of electronic components, and this change tends to be in an unfavorable direction. Blizzard has a great impact on photovoltaic power stations. Too thick snow will lead to over icing of components, affecting the power generation and life of the system, resulting in a decline in power generation and even stop work. For solar inverter, it is a severe test. Cold climate conditions may make the inverter can not work steadily, such as can not start, frequent alarm, power generation reduction and other problems.

How to choose inverter to deal with the erosion of extreme weather?
1.Select components of wide range of working temperature to fully meet the low temperature service conditions.
2.Takes full account of the demand for low temperature work in the design of the product, leaving enough margin (including capacity margin and time margin).
3.The product should be tested for a long time at low temperature to ensure the validation of theoretical value.

How to do the inspection of the outdoor inverter well?
After long time use, there will be aging phenomenon in the connection of inverter.The inverter has its own insulation impedance detection, which can reliably protect the inverter. At the same time, it needs to pass the on-site inspection, and the thermal imager can scan the connection points of each cable at work; Check whether the inverter PV input terminal is stable or loose; Whether the AC terminal is aging and loosening; Whether there is grounding in the PV line under the sun plate.

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

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...
