1. Power control function:
2. Communication function: a simple indicator, protocol communication, background management.
3. Perfect protection: reverse electrical protection, short circuit, over current
How Solar Charge Controller Work?
1. Solar Charge Controller Exit the protection voltage
Some customers often find that the bright solar lights for some time, especially the consecutive rainy days, the street will be several days or even many days off, testing the battery voltage is normal, controller, lights, were not failures.
It used to make a lot of works to doubt, in fact, this is the “exit voltage protection,” the voltage problems, set this value higher, the voltage the longer the recovery time after, it caused a lot of days are not bright lights.
2. LED lights constant current output
LED Because of its characteristics, must be constant through technical means or limiting them, or not work properly. LED lights are often driven by an additional power supply to achieve constant current LED lights, but the driver has accounted for the light of the total power of about 10% -20%, such as a theoretical value of 42W of LED lights, plus After driving the actual power may be around 46-50W. In the calculation of solar panel power and battery capacity, it must pay more to meet the 10% -20% power consumption caused by the driver. In addition, the more the drive to produce more of a link failure. Industrial version of controller software without power constant, high stability, reducing overall power consumption.
3. Solar Charge Controller Output time
The controller general of ordinary lights can be set only after 4 hours or 8 hours in a number of hours off, has been unable to meet the needs of many customers. Industrial version of the controller can be divided into three periods, each period of time can be set, according to the different use of the environment, each time can be set off. For example, some plant or scenic night no one can put the second period (night) turned off, or the second and third sessions are closed to reduce the cost.
4. LED light output power adjustment
Among the application of solar energy lamps, LED lamps are most suitable for output by pulse width modulation to achieve different power. Pulse current limit or restrict the same time, the duty cycle of LED lights to regulate the output, for example, a single 1W LED 7 series 5 and the total 35W of LED lights at night discharge, can be late at night and early morning hours, respectively power regulation, such as regulating the night into 15W, am adjusted to 25W, and lock the current, so that can meet the night lighting, but also saves the battery plates, battery configuration costs. The long-term trials show that pulse width modulation mode LED lights, the heat generated by the whole lamp is smaller the more that can extend the LED life.
Some light power plant in order to achieve the purpose of the night, the LED lamp made of 2-way power-house, at night all the way off the power to achieve the output power by half, but the practice proved that this method will only lead to the first half of the light source failure, inconsistent or brightness all the way to light early damage.
5. Solar Charge Controller line loss compensation
Line loss compensation controller is currently difficult to do routine, because of the need software settings, depending on the diameter and length to give automatic compensation. Line loss compensation in the low-pressure system is very important, because the low voltage, line losses are relatively large, without a corresponding voltage line loss compensation, the output voltage may be lower than a lot of input, which would result in battery in advance under-voltage protection, battery capacity is the practical application of discounted rates. It is worth noting that we use the low-pressure system, in order to reduce line losses drop, try not to use too thin wire, cable should not be too long.
6. Solar Charge Controller Thermal
Many controllers in order to reduce costs, without considering heat dissipation, so that the larger the load current or charging current is large, the heat increases, the controller was increased resistance of field management, resulting in charging efficiency dropped significantly, field service life after heat pipe greatly reduced or even destroyed, especially in summer, the outdoor ambient temperature is high, so a good cooling device controller should be essential.
7. Solar Charge Controller MCT charge mode
Conventional solar charge controller model is copied the city’s three-stage battery charger charging method, that is, constant current, constant voltage, float three stages. Electricity grid because of infinite energy and, if not for constant current charging, the battery charge will directly lead to explosive damage, but the solar panels power streetlight system is limited, so the controller to continue to use electricity is not constant current charging method Science, if the solar panels generate more than the current limit of the current controller first, then caused a decline in charging efficiency.
MCT way to track the solar panels charge the maximum current, not to cause waste, by detecting the battery voltage and temperature compensation value calculation, when the battery voltage is close to the peak time, and then trickle to pulse charging method, both to charge batteries also prevents battery overcharge.
