One: exit protection voltage
Some customers often find that solar lights in the bright after a period of time, especially after a continuous rainy days, the street will be a few days or even many days do not light, the detection of battery voltage is normal, the controller, the lights are not fault.
This problem has been a lot of engineers doubts, in fact, this is the "exit undervoltage protection" voltage value of the problem, the higher the value set, after the recovery time in less pressure, it will cause a lot of days can not be bright light.
On this issue, the Industrial Controller allows each customer to set the voltage to exit the protection according to the configuration. But it is worth noting that the configuration of the battery panel must be reasonable, if the battery charge per day can not meet the night's discharge, the long run, the battery is often in the depth of discharge, life is greatly reduced, so the battery must be installed to enlarge the margin , The greater the configuration of the battery, exit the protection of the voltage can be set lower, this will not cause the impact of the battery.
Two: LED lamp constant current output
LED due to its own characteristics, must be technical means to its constant current or current limit, or can not be used normally. Common LED lights are by adding a drive power to achieve the constant current LED lights, but this drive accounts for the total power of the total 10% -20%, such as a theoretical value of 42W LED lights, plus After driving the actual power may be about 46-50W. In the calculation of solar panel power and battery capacity, you must add 10% -20% to meet the drive caused by the power consumption. In addition, the addition of a drive on the more than a link. Industrial controller through the software without power consumption constant current, high stability, reducing the overall power consumption.
Three: output time
Ordinary controller can only be set to turn on the lights after 4 hours or 8 hours and several hours off, has been unable to meet the needs of many customers. Industrial controller can be divided into three periods, each time period can be set arbitrarily, according to the use of different environments, each time period can be set to a closed state. For example, some factories or scenic no one at night, you can put the second time (late) closed, or the second and third period are closed, reduce the use of cost.
Four: LED light output power adjustment
In the application of solar energy lamps, LED lights are most suitable for the pulse width adjustment to achieve the output of different power. Limit the pulse width or limit the current at the same time, the LED output of the entire duty cycle to adjust, for example, a single 1W LED 7 string 5 and a total of 35W LED lights, at night discharge, you can late and early morning hours were Power adjustment, such as the night adjusted to 15W, the morning adjusted to 25W, and lock the current, so that can meet all night lighting, but also saves the battery, battery configuration costs. Long-term test proved that the pulse width adjustment mode of the LED lights, the whole light generated by the heat to be much smaller, to extend the life of the LED.
Some light factory in order to achieve the purpose of saving the night, the LED lights made of internal 2-way power, turn off all the way to power to achieve half of the output power, but the practice has proved that this method will only lead to half of the light source first light Failure, brightness inconsistency or an early light source damage.
