How to judge the quality of the solar street light controller?
When the charging voltage of the solar controller is higher than the protection voltage, it will automatically shut down to charge the battery. After that, when the voltage drops to the maintenance voltage, the battery will enter the floating charge state. When the voltage is lower than the recovery voltage, the float charge will be turned off and enter the equal charge state. When the battery voltage is lower than the protection voltage, the controller automatically turns off the output to protect the battery from damage; when the battery is recharged, it can automatically restore power. In order to launch new products and occupy the market as soon as possible, many street lamp manufacturers often launch the market before the products are fully mature. They have not done some complete tests at all. Such solar controllers will inevitably have many technical problems. Therefore, we need to understand the company's product information when choosing a solar controller to analyze the maturity of its product technology. The charging mode of the conventional solar controller is to copy the three-stage charging method of the mains charger, namely the three stages of constant current, constant voltage, and floating charge. If the current generated by the battery panel is greater than the current limited by the controller, it will cause a drop in charging efficiency. The MCT charging method is to track the current of the battery board without causing waste. By detecting the voltage of the battery and calculating the temperature compensation value, when the voltage of the battery is close to the peak value, the pulse-type trickle charging method is adopted, which can make the battery fully and also fully charged. Prevent the battery from overcharging. Coastal users can realize that a non-waterproof controller may corrode the circuit board in about half a year. In order to facilitate maintenance, most customers put the controller on the base of the light pole. However, many light pole manufacturers have poor airtightness of the base. When it rains, rainwater will enter, so the controller that is not completely waterproof is very useful. It may be corroded due to water entering. When the amount of rainwater entering is large, the controller circuit will be short-circuited in an instant.
