Solar Street Lights
The main light source of solar street lights is solar energy derived from sunlight, which is a very unique and environmentally friendly energy source. It is important to understand that solar street lights rely on sunlight to charge solar panels during the day, converting light energy into electrical energy and storing it in batteries. So, what are the protection modes for solar street lights?
Uniform Voltage Control
During the actual protection process of
solar street lights
, after the charging is completed, it is observed that the entire battery is maintained by the charge-discharge controller for a period of time, allowing the voltage to naturally drop. When the voltage returns to a certain level, it enters a uniform charging state. The duration of uniform charging should not be excessively long.
Over-Discharge Protection Cut-off Voltage
During actual charging, the battery of the
solar street lights
should not be discharged below a specified value, which is essentially the normal requirement. For safety reasons, a 12-volt battery is usually set to a protective cut-off voltage. This serves as a temperature compensation and aids in correcting the zero drift in the entire circuit.
Direct Charge Protection Cut-off Voltage
When using
solar street lights
, if the battery voltage is relatively low, a high current or relatively high voltage can be used for charging. The voltage protection during charging typically corresponds to the over-charge protection cut-off voltage. The battery voltage must not exceed this level during charging, otherwise damage may occur.
