- 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: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 can not charge what is the reason
- Float control point voltage: the general charge is completed, the battery is also standing for some time, so that the end voltage naturally fall, when the drop to the "maintenance voltage" point, it entered the float state, are currently using PWM (both Pulse width modulation), similar to the "trickle charge" (that is, a small current charge), a low battery voltage to charge a little, a low charge on the point, an share of a place to avoid the battery temperature continues to rise, This is very good for the battery, because the internal temperature of the battery charge and discharge a great impact. In fact, the PWM method is mainly designed to stabilize the battery terminal voltage, by adjusting the pulse width to reduce the battery charge current. This is a very scientific charge management system. Specifically, at the end of the charge, when the remaining capacity of the battery (SOC)> 80%, it is necessary to reduce the charging current to prevent excessive release (oxygen, hydrogen and acid gas) due to overcharging.
- Q:Solar panels for solar panels
- Using the series PWM charging the main circuit, so that the charging circuit voltage loss than the use of diode charging circuit reduced by nearly half, the charging efficiency of 3% -6% higher than non-PWM, increased power consumption; over discharge recovery to enhance the charge, Normal direct charge, float the automatic control mode so that the system from a longer life; at the same time with high precision temperature compensation; intuitive LED LED indicates the current battery status, allowing users to understand the use of the situation; all control all use industrial chip ( Only with I industrial controller), in the cold, high temperature, humid environment to run freely. At the same time the use of crystal timing control, timing control accuracy.
- 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:How to debug a solar street light controller
- Debug mode (6 ·): used for system debugging, when the optical signal is closed load, no light signal load, easy installation and commissioning check the correct installation of the system. Normally open mode (7 ·): The power load remains in the output state, which is suitable for 24 hours power supply.
- Q:Solar water heater controller power screen is not displayed
- Check the circuit, if the circuit is good, then you have to get the seller to see, because you know where is bad, you no tool material, can not change.
- 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:Solar controller red light flashing
- Installation of the controller should pay attention to: 1, waterproof; some of the controller on the market is not easy to produce waterproof, easy to penetrate the water vapor in the poles, resulting in short circuit and other issues; 2, pay attention to the controller and system rationality, 3, the main function of the controller is to protect the battery, must pay attention to.
- 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
