The solar street light controller is an intelligent charge and discharge controller that is controlled and displayed by a microprocessor. It uses high-quality, low-loss, long-life components to ensure reliable performance, allowing the solar street light system to operate normally for a long time and reduce maintenance costs. So, what functions does the solar street light controller have? Here are some insights shared by Century Sunshine Lighting:
1. Overcharge Protection: The controller automatically disconnects charging when the charging voltage exceeds the protection voltage. Subsequently, when the voltage drops to the maintenance voltage, the battery enters a float charge state. Once below the recovery voltage, the float charge stops and the battery transitions to an equalization charge state.
2. Over-discharge Protection: When the battery voltage drops below the protection voltage, the controller automatically shuts off the output to protect the battery from damage. After the battery is recharged, power supply is automatically restored.
3. Load Overcurrent and Short Circuit Protection: If the load current exceeds 10A or a short circuit occurs, the fuse will blow, and after replacement, the system can continue to be used.
4. Lightning Strike Protection: When a lightning strike occurs, a varistor can prevent damage to the controller.
5. Anti-Reverse Charging Function: A Schottky diode is used to prevent the battery from charging the solar panel.
6. Overvoltage Protection: The controller automatically shuts off output when the voltage is too high, protecting electrical appliances from damage.
The functions of the solar street light controller have been shared here. The solar street light controller is an essential component of the solar street light system and serves as the control core. It connects the lights, batteries, and photovoltaic panels to ensure the entire system operates normally. If an unsuitable controller is used, the lights may not function properly, potentially damaging either the controller or the lights.
