The Role of Solar Controller

The solar controller protects the voltage

Some customers have encountered solar street light for some time after a period of time is not bright phenomenon, and this phenomenon occurs in continuous rainy weather, by detecting the election of batteries, lights, controller no problem. What is the reason for this? This phenomenon is because the voltage out of under voltage protection there is a problem, to avoid the occurrence of this problem requires you to choose a good performance of the solar controller.

The solar controller can control the current output

In the use of solar lights, solar street lights LED lights due to their own characteristics, must be through the solar controller for its constant current or current limiting to normal use, but the common solar LED lights are added by a drive power to achieve the lamp of the constant current, this will take up a large proportion of the total power of the lamp, the emergence of solar controllers undoubtedly solve this problem.

The solar controller can control the output period

Imagine if your solar lights in the daytime in the lighting, is not a waste? Solar controller will be able to control its lighting period to ensure that no lighting during the day and night lights. This saves maintenance costs and costs.

The solar controller can assist in heat dissipation

Many manufacturers of solar street lights and other products in order to save costs, the choice of solar controller will ignore the heat, this is actually a very wrong behavior, if you ignore the heat, it is undoubtedly the load current and charge current withstand capacity of the load, which will reduce the charging efficiency.

Using a digital LED display and settings, one-click operation to complete all settings, the use of extremely convenient and intuitive role is to control the working status of the entire system, and the battery played overcharge protection, over discharge protection. In the larger temperature difference, the qualified controller should also have the function of temperature compensation.

How to Connect Solar Panels and Batteries?

How to connect solar panels and batteries to produce a stable voltage can provide power? Can be directly connected? Is it feasible to charge the battery with a solar panel while the battery is supplying power to the external circuit?

Solar cells and batteries connected, it is best to use a photovoltaic charging controller. This can control the output voltage of solar cells, and can protect the battery is not overcharged, but also at night when the solar cells do not generate electricity to prevent the battery of the electricity back.

The connection is as follows: Solar battery ---- photovoltaic controller --- battery --- DC load.

In this case, the load of electricity will be given priority to the direct use of solar cell power, the remaining charge to the battery. On the contrary, if the solar battery power is not enough, in the case of solar power to the battery is fully charged at the same time, will also take power from the battery.

Solar Energy: Solar Energy generally refers to the sun's radiation energy, in the modern general for power generation. Radiation energy released by the high-temperature fusion reaction inside the sun about two billionth of which reach the Earth's atmosphere, is the source of light and heat for the Earth. Earth-forming organisms live mainly on the heat and light provided by the sun. Know how to sun dried objects, but reduced in fossil fuels, only interested in the further development of solar energy. The use of solar energy has passive use (light and heat conversion) and photoelectric conversion in two ways. Solar power is a new kind of renewable energy. The broad sense of solar energy is the source of many power on earth, such as wind energy, chemical energy, water potential energy and so on. Solar energy is generated by the fusion of internal hydrogen atoms produce a huge nuclear energy generated by the energy from the sun's radiation.

The Mainly Function of Solar Controller

Self-test: When the controller is affected by natural factors or man-made operation is not the time. You can let the controller self-test. Let the person know whether the solar controller is intact. Reducing the number of unnecessary work hours. In order to win the project quality and duration to create the conditions. (D series of these products have this feature, see here on the "Modifier Manual")

Anti-anti-charge protection: to prevent the black days, or cloudy day without sunlight. The battery of electricity on the solar cell discharge (often said to be anti-charge). So as not to waste energy and damage the system.

Overcharge protection: When the battery is full to stop charging the battery, if too much charge will make the battery inside the chemical composition of other reactions, NI battery will crystallize, which directly affect the battery capacity and life.

Over-discharge protection: When the battery power is low to stop the battery discharge, if too deep discharge will also affect the battery capacity and life.

Recovery Interval: The recovery interval for overcharge or over-discharge protection. In order to avoid the line resistance or battery self-recovery characteristics caused by the work load of the fight.

Temperature compensation: monitor the battery temperature, the charge and discharge value into the very correction, so that the battery work in the ideal state.

Light control: more for automatic lighting, when the environment is bright enough. The controller will automatically turn off the load output; and dark environment will automatically open after the load. To achieve the function of automatic control.

How to Choose the Models of Hanfong Solar Charge Controller?

How to choose the right model on lots of solar controller models? In a general way, basically to consider the bigger one between the ratio of solar panels power and the battery voltage with the ratio of load power and the battery voltage. For example, the load power is 60w, panels is 100w, battery voltage is 12v, 60w/12v=5A, 100W/12V=8.333A.So, to choose 12v 10A solar controller is the best.

Of course, you also need other functions, that is going to tell your demand. You can choose the utility complementary controller when the battery without electricity but you have to stay in work. You can choose the controller taking half power  when you need the light in full power before 5 hours, but the half power later. You can choose double time frame controller when you need the controller working from the black to 0'clock, and at 4 am. to the morning. You can choose dual controller when you want the system has two load power.
