How to distinguish the quality of solar street light controller.
As the core component of the solar street light, the solar street light controller plays the role of charging and discharging. If there is a problem with the controller, the entire street light will not work properly, and it may even cause damage to the battery. If it causes overheating, it can also cause a fire.
However, with market competition, the price of solar street light controllers is getting lower and lower. In this case, can the quality of the controller be guaranteed?
1. Solar street light controller with what charging skills.
At present, the mainstream charging skills on the market include three types of skills: switching, PWM, and MPPT. Which charging technology is used directly determines the quality and cost of the controller. MPPT street lamp controller is better than PWM, and PWM is better than switching. And its price is directly proportional, and the skill difficulty is also very complicated.

2. Whether the operation and installation of the solar street light controller is convenient.
Because in the construction site, there are some workers who are not familiar with the use and characteristics of the product, so there is a silk-printed street light controller wiring diagram on the housing of the street light control, and the installation is simple and quick, and the marking is clear. The setup is simple and easy to understand. If the installation setting is too cumbersome, it may cause the system to work abnormally.
3. Waterproof effect of solar street light controller.
Everyone knows that solar street lights are installed outdoors and work around the clock. Working in a harsh working environment all year round, if there is no waterproof protection, it will easily lead to a series of problems such as corrosion, rust, and line aging, which will seriously affect the service life of the controller. All waterproofness is an important criterion for judging a controller. The current mainstream method is to use aluminum alloy shell and full potting treatment. IP68 is also the main waterproof method currently used.
