Product Description:

Descriptions: 

 

A charge controller, or charge regulator is basically a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and current coming from the solar panels going to the battery. Most "12 volt" panels put out about 16 to 20 volts, so if there is no regulation the batteries will be damaged from overcharging. Most batteries need around 14 to 14.5 volts to get fully charged.

Q:What is the use of solar controller
Solar controller is the power (including battery and electricity), solar panels, the load of the center connector, why say so? Because the above components must be connected with the solar controller in order to be able to achieve the work, in general, the controller's main function is to control the solar panels on the battery charge or disconnect, control the load power supply or disconnect, control the city Electricity and battery switching between the main is that these features, and other, such as light control to open, light control off, timing delay off, manual switch, and debugging and other functions.
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 does not heat how to heat
Solar energy itself is the hot water of the stuff, certainly can be heated, but not with electric heating only.
Q:What brand of solar controller is good
In today's solar industry, brand-name products in terms of quality to after-sales service, are guaranteed. And consumers want to compare through their own observation to choose, there are some difficulties. Such as the key components of solar water heaters is the insulation of the tank and the material and thickness of the liner steel, only the water tank can be destroyed before the amount of liner thickness and material. There is the quality of the vacuum tube, these things even if our industry people, without destroying the product, do not use precision instruments in the case, can not be identified
Q:Solar controller red light flashing
Solar controller flashing red light according to the different brands of the representative of the meaning of the controller are not the same, but in general terms, the red light flashing a saying that the battery is charging the battery is expressed as a red light flashing, green , The yellow light does not shine; another kind is the battery high pressure state or battery low voltage state that is red light flashing, green light does not light, hope to help you
Q:Solar controller can not charge what is the reason
Overdischarge protection Termination voltage: This is better understood. Battery discharge can not be lower than this value, which is the provisions of the national standard. Although the battery manufacturers have their own protection parameters (standard or line standard), but ultimately to close to the national standard. It should be noted that, for safety reasons, the general 12V battery over the protection point voltage plus 0.3v as a temperature compensation or control circuit zero drift correction, so 12V battery over discharge protection voltage is: 11.10v, then 24V system over discharge protection point voltage is 22.20V. At present, many manufacturers of charge and discharge controller are used 22.2v (24v system) standard.
Q:What are the solar controller models?
The controller is designed for solar DC power supply system, solar DC street lamp system design, and the use of a dedicated computer chip intelligent controller. Use a one-touch touch switch to complete all operations and settings. 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:How to debug a solar street light controller
Pure light control (0): When there is no sunlight, the light intensity drops to the starting point, the controller delay 10 minutes to confirm the start signal, according to the set parameters to open the load, the load began to work; when there is sunlight, light intensity to 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:What is the meaning of the 30A solar controller?
The maximum current is 30A
Q:What is the power of the solar controller?
Generally in accordance with the current to count. Depending on your system voltage, such as 12V or 24V
