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.
