Q:Solar controller 10a, a represents what
A (Ampere) is the basic unit of current expressed in the International System of Units, referred to as Ann, Symbol A. 10A refers to the controller can control the output device maximum current of 10A, select the load device when the device current can not exceed this value
Q:What is the power of the solar controller?
If you are 12V system, select the 10A controller, then the controller with the power of 12V × 10A = 120W, up to the battery with no more than 150W.
Q:The principle of solar controller
Solar energy is a kind of radiant energy, it must be by means of energy conversion device can be transformed into electric energy.This kind of radiant energy into energy energy conversion device, is the solar cell.C solar cell is the use of photoelectric conversion principle of the sun's radiation through the semiconductor Material conversion into electrical energy devices, this photoelectric conversion process is often called "photovoltaic effect", solar cells, also known as "photovoltaic cells." When the sunlight to the P, N type two different types of conductive semiconductor Material under the PN junction, under certain conditions, the solar radiation is absorbed by the semiconductor material to form a built-in electrostatic field.If the two sides from the built-in electrostatic field leads to the electrode and connected to the appropriate load, it will form a current, which is The basic principle of solar cells. Monolithic solar cell is a thin piece of semiconductor PN junction. Under standard lighting conditions, the rated output voltage is 0.48V. In order to obtain a higher output voltage and larger capacity, often more than one solar cells connected together , At present, the solar cell photoelectric conversion rate is generally around 15%, individual developed countries, laboratory solar cell photoelectric turn The rate has been able to reach about 30%.
Q:Solar controller water level display is not correct how to do
Re-adjust the water level to control, choose their own water.
Q:How to adjust the solar controller
Solar controller mode: 1, pure light control mode: when there is no sunlight, the light intensity dropped to the starting point, the controller delay 10 minutes to confirm the start signal, according to set the parameters to open the load, the load began to work; when there is sunlight , The light rises to the start point, the controller delay 10 minutes to confirm the closure of the signal after the closure of the output, the load stops working.
Q:How the solar panels with the controller
Light control on + delay off - open delay + light control off the double time mode: the work process is open when the dark load (light control on), delay to set the first time after the closure of the load, turn off the load After the day until the day before the set of the second time to open the load again, to the dawn when the load off (light control off), the night when the load is closed to save power. The controller uses fuzzy control to automatically identify and effectively correct the darkness to the dawn of the entire night time, that is, according to the length of the night to automatically adjust the time to close the load at night to ensure that the load only in the dark and before dawn Set the time period to open, the other time is closed.
Q:Solar controller use
And then anti-backlash protection, short circuit protection, overcharge and over discharge protection
Q:Solar controller one machine how
You should include a charge and inverter as one of the machines. This product is also very good, but for many users is not very applicable, such as I hope to enter the input, but the output power can not meet, and configure the inverter is more waste. If your needs and configuration just right, it is still relatively easy to use. The cost of the above is higher.
Q:How does the solar controller set up Sheung Shui?
Press the Set key to enter the settings of these two parameters. At this time, the parameters of the upper limit of the temperature and the upper limit of the water level are kept flashing. Use the water level key to change the upper limit of the water level (factory 100% ), Use the heating water temperature key to modify the temperature upper limit value (factory 50, setting range 50-90), wait 5 seconds to automatically save and exit.
Q:What is a solar controller?
Solar controller is used to control the charge and discharge and has a reverse charge protection, overcurrent protection, overload protection, short circuit protection, digital display parameters and other functions of electronic equipment. To select a solar controller, it is recommended to choose from the ENF website. Which includes the well-known domestic and foreign manufacturers of information and product information. Under normal circumstances the controller has waterproof protection measures. To choose according to different needs
