The professional team selects Lingrui as the manufacturer of street lights, with direct sales technical guidance and professional construction team.
The after-sales service is perfect and the price is reasonable, and the professional design and manufacturing of engineering street lights and outdoor lighting fixtures are directly sold by manufacturers, providing worry free after-sales service.
Component 1: Solar panel
In southern regions where there are more rainy days and less sunlight, it is better to use monocrystalline silicon solar cells because their performance parameters are relatively stable.
Component 2: Solar controller
1: System functions
● Charging
● Discharge
● Automatic switch on/off lights
● Automatic power reduction
When the battery voltage drops to the set voltage, the controller begins to reduce the output power of the light source in a certain proportion to achieve the function of extending rainy days.
This function is actually a double-edged sword, with the advantage of greatly extending the support time on rainy days.
The disadvantage is that during the long-term rainy season, the battery will fall into low potential charging and discharging for a long time, which increases the risk of battery overdraft and has no impact on the battery's lifespan Having adverse effects.
Especially for lead-acid batteries, it is easy to overdischarge and shorten their lifespan.
2: Protection function
● Overcharging.
The important function of overcharging protection for batteries is to prevent overcharging, which is of great significance for maximizing battery life.
● Over discharge.
Overdischarge is also a protection for the battery. When the battery voltage drops to the set protection voltage, the controller switches off the load and no longer allows the battery to consume electricity.
It is not until the battery voltage is recharged to the recovery voltage that it begins to discharge again.
● Wiring protection.
Wiring protection includes reverse connection protection, short circuit protection, and open circuit protection, all of which are aimed at protecting the load.
If the load has reverse connection, short circuit, or open circuit conditions, the controller will turn off the output to the load.
However, if the battery and solar panel are connected incorrectly, the controller cannot be protected, so it is important to pay attention when wiring.
The incorrect wiring of the battery and solar panel may directly damage the controller.
