What conditions should be met for the selection of solar street light controllers?

Regardless of the size of the solar street light, a well-functioning charge-discharge controller is essential. The following functions are required: (1) High voltage (HVD) disconnection and recovery function: The controller shall have the function of input high voltage disconnection and recovery connection. (2) Low-voltage (LVG) alarm and recovery function: when the battery voltage drops to the low-voltage alarm point, the controller should be able to automatically send out an audible and visual alarm signal. (3) Low voltage (LVD) disconnection and recovery function: This function can prevent the battery from over-discharging. Connect the load through a relay or electronic switch, which can automatically cut off the load at a given low voltage point. When the voltage rises to a safe operating range, the load will automatically reconnect or require manual reconnection. (4) Protection functions: ①Circuit protection to prevent any load short circuit; ②Circuit protection to prevent internal short circuit of the charge controller; ③Protection against reverse discharge of the battery through the solar cell module at night; ④Protection against load, solar cell module or battery polarity Circuit protection for reverse connection; ⑤Protection against breakdown caused by lightning strikes in many minefields. (5) Temperature compensation function: When the battery temperature is lower than 25℃, the battery should require a higher charging voltage in order to complete the charging process. Conversely, above this temperature the battery requires a lower charging voltage. Usually the temperature compensation coefficient of lead-acid batteries is -5mv/oC/CELL. The solar LED street light adopts LED light source, which has a long service life, up to 1,000,000 hours, low operating voltage, no need for an inverter, and high light efficiency. With the advancement of technology, the performance of LED will be further improved. is a trend. For details, please log in: www.chz-lighting.com.
