Solar controller which used for solar photovoltaic systems to coordinate solar panels, batteries and loads is a very important component in photovoltaic system, it makes the whole solar system work effiently and safe.
Lighting controller is specially used for street lights with time control and light contro, wellsee manufacture 12V/24V/48V 6A/10A/15A/20A/25A/30A/40A/50A/60A specifications.
Functions:
1. Wellsee Solar Street Lamp Controller can prevent the battery from over-charging and over-discharging.
2. Wellsee Street Light Controller can prevent reverse charging (the battery charges the solar panel).
3. Wellsee waterproof lamp controller can prevent reverse connection of the battery and solar panel.
4. Wellsee solar garden light controller will start up the lighting system in the evening automatically according to the intensity of the light.
5. Wellsee Solar Lighting Controller will shut down the lighting system according to the time setting or shut down the lighting system automatically when it is dawn.
6. Wellsee Solar road lamp controller has a LET indicator of the working condition of charging and discharging:
l One piece of Charge Indicator LED (mark: Charge). When the light is on, the battery is being charged; flickering light means floating charge, no light means charging stops.
l One piece of Load Indicator LED (mark: Light). When it is bright, there is output and load can work; if LED goes out, there is no output and the load cannot work.
l Battery indicator: red under =voltage Green =full Yellow =normal
Lighting controlellers can set time except for basic functions, some types can adjust light strength.
Moreover, there are many other types of solar controller:
Some kind solar controller can work 24 hours a day, as they own large power consumption, it will consume some energy, the best choice for power control in less than 1 mA.
Some can automatically track the maximum current of solar panels,especially in the winter or periods of insufficient light, 10%-30% higher effiency than normal.
Some are two-way adjustable solar controllers, the solar controller has a power adjustment has been widely promoted, few pedestrians at night time can be automatically shut down one or two light, saving electricity, you can adjust for power LED lamps . In addition to the above selected power-saving features, it should also focus on batteries and other components of the controller protection features, such as a trickle charge mode of the controller can well protect the battery, increasing battery life, the other to set the controller undervoltage protect the value, try to protect the value of the transferred voltage in ≥ 11.1V, to prevent battery over discharge.
When designing lighting controllers, the Solar lights are the sun’s light as the main source of energy during the day will be free to charge at night use. Without laying any complex and expensive circuits and pipelines, but also the layout can be adjusted lighting, security, energy efficient and free of other pollutants,the process of charging and the use of switches with automatic light control, without manual operation, stable and reliable, saving electricity costs and power resources, maintenance-free, solar street light utility has been fully recognized by the people, this paper is based on single chip controller for solar street lamp design, 12V and 24V batteries can be automatically identified, the battery can be realized scientific management, can be indicative of the battery, overvoltage, undervoltage, etc. running, and has two load outputs, each load rated current up to 5A, two load can be arbitrarily set to the same light, timing light, separate timing and other variety of operating modes, while the load current, short circuit protect function; and a higher degree of automation and intelligence.
Wellsee solar controller has the battery charging management. Battery open circuit protection: if the battery open circuit, if the normal charge in the solar cell, the controller will turn off the load, to ensure that the load is not damaged, if at night or when the solar battery is not charging, the controller due to its lack of power, not there will be any action.
Wellsee solar controllers have overcharge Protection: charging voltage higher than the protection voltage (14.4V), automaticaly cut off the battery charge, when the battery voltage is lower than the protection voltage (11V), the controller automatically turns off the load switch to protect battery from damage.
Through the PWM charging circuit (intelligent three-stage charging), can maximize the effectiveness of solar panels to improve the efficiency of the system charge. The system supports reverse battery, over charge, over discharge. Load output control and detection circuit design of the system two load output, the output of each channel has independent control and inspection, has improved the over-current, short circuit protection.
