4 methods to distinguish the quality of the solar controller

1.Using what kind of charging technology

At present, there are three technologies in the mainstream of the market, such as switching, PWM and MPPT. What kind of charging technology is used directly determines the quality and cost of the controller. The solar MPPT charge controller is better than the PWM, and the PWM is better than the switch type. And the price is also proportional, the technical difficulty is also more complex.

2.Whether the operation and installation of the solar controller is convenient

Because the workers at the construction site are often not very familiar with the use and characteristics of the products. Therefore, it is best to have the wiring diagram of the screen lamp controller on the shell of the street lamp controller, which is easy to install, clearly marked and easy to understand. If the installation is too cumbersome, it may cause the system to work unnormally, resulting in customer complaints.

3.The waterproof effect of solar street lamp controller

It is known that solar street lamps are installed outside and work all day. Perennial work in bad working environment, if waterproof is not good, it is easy to cause corrosion, rust, aging lines and a series of problems, which seriously affect the life of the controller. So waterproofing is an important index to judge a controller. The mainstream way is to use aluminum alloy shell and full potting treatment. IP68 is also the highest waterproof index at present.

4.Technical maturity of solar street lamp controller

In order to speed up the launch of new products and seize the market as soon as possible, many manufacturers rush to launch the market without the full maturity of products. They haven’t done any complete tests at all. Such products will inevitably encounter many technical problems. So when we choose the solar street lamp controller, we need to know the company’s previous product information to analyze the maturity of its product technology.

SOROTEC Solar MPPT Charge Controller

1.Adopt advanced MCU microprocessor control technology.
2.12v/24v self detect to choose output voltage.
3. Advanced MPPT technology ,high converting efficiency higher than 97% for minimizing energy loss.
4.Capable of selecting different charging mode for various type of batteries
5.capable of connecting additional DC load for wide applications.
6.Three stage charge control system(bulk , absorption, and float mode)with optional temperature compensation.
7.LED indicators display charge status in real time.
8.Pulse Width Modulation(PWM)technology combined with a multi-stage charge control algorithm leads to superior charging and enhanced battery performances.

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...
