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 one machine how
Built-in high-precision step-up constant current source, no need to reprovision LED constant current source, can directly drive LED lamp beads, single string up to 18, up to 9 groups in parallel, the output power can reach 160W, to meet all the market LED street lamps;
Q:How to choose a solar controller
With full short-circuit, overload, unique anti-reverse protection, full, over-automatic shutdown, recovery and other full-function protection measures, detailed charge instructions, battery status, load and a variety of fault instructions. The controller through the computer chip on the battery terminal voltage, discharge current, ambient temperature and other parameters related to the battery capacity of the sample, through the special control model calculation, to achieve the characteristics of the battery discharge rate, temperature compensation correction of high efficiency, high accuracy rate control , And adopted a high efficiency PWM battery charging mode, to ensure that the battery work in the best condition, greatly extending the battery life. With a variety of work patterns, output mode selection, to meet the various needs of users.
Q:Solar panels for solar panels
The use of a single chip and special software to achieve the intelligent control; the use of battery discharge rate characteristics of the correct discharge control. The discharge voltage is controlled by the discharge rate curve of the control point, eliminating the simple voltage control overdosed inaccuracies, consistent with the inherent characteristics of the battery, that is, different discharge rates have different end voltage. With overcharge, over discharge, electronic short circuit, overload protection, unique anti-reverse protection and other automatic control; the above protection does not damage any parts, do not burn insurance;
Q:What is a solar controller?
The controller is the microcomputer on the water valve above the show solar water tank temperature control Sheung Shui to a certain level of electronic valve will automatically shut down the water is not on the water level to the most electronic valve will automatically open the solar water tank temperature is higher than 75 degrees above the water tank That is, no water, the electronic valve will not open to avoid solar vacuum tube break
Q:How to debug a solar street light controller
Press the button for more than 3s digital tube began to flash, the system into the adjustment mode, release the button, each press a button, digital tube digital will change a number until the digital display of the number of users from the table selected mode corresponding The number of so far, such as digital tube to stop flashing or press the button more than 3s to complete the set.
Q:What is the system voltage of the solar controller?
Solar controller battery terminal 12V battery, the load side can be directly connected to the 12V DC lamp? ----- This DC lamp, are 12V, can.
Q:What is the meaning of the 30A solar controller?
Solar controller above the marked 30A is the maximum current of the controller is 30A, the general solar controller has 12 / 24V10A 12 / 24V / 15A 12 / 24V20A 12 / 24V30A 24 / 48V10A 24 / 48V20A 24 / 48V30A 24 / 48V60A and so many Type of model. Customers can choose according to their own power size! The The When purchasing the capacity of the controller must be greater than the capacity of solar panels and load! The The
Q:Solar controller use
And then anti-backlash protection, short circuit protection, overcharge and over discharge protection
Q:How the inverter is connected to the solar controller
The controller combines the logic controller and the microprogram controller, both of which have strengths and weaknesses. The combination of logic controller design trouble, complex structure, once the design is completed, can not be modified or expanded, but it is fast. Microprogram controller is easy to design, simple structure, modify or expand are convenient, modify the function of a machine instruction, just repeat the corresponding micro-program; to add a machine instruction, just add a micro-program in the control memory, However, it is done by performing a short process. The specific comparison is as follows: Combination logic controller, also known as hard-wired controller, composed of logic circuit, completely by hardware to achieve the function of the instruction.
