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:What is the system voltage of the solar controller?
Solar controller is called solar charge and discharge controller, is used in solar power system, the control of multi-channel solar cell battery charging and battery to the solar inverter load power supply automatic control equipment.
Q:What are the solar controller models?
Contact manufacturers, different manufacturers adjustable model is not the same as our company is this model: (light control + time control, time control, testing three models) Beijing reed hi Yuan New Energy Technology Co., Ltd.
Q:Solar water heater controller power screen is not displayed
Probably the relay is burned out
Q:How to adjust the solar controller
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.
Q:Solar controller 10a, a represents what
10A indicates that it can control the maximum current is 10 amps, the use of the load can not be greater than this current.
Q:How the inverter is connected to the solar controller
What are your requirements, the inverter is the battery
Q:Solar controller water level display is not correct how to do
If not explain the control board or tube water level sensor bad, consider, for reference!
Q:How does the solar controller set up Sheung Shui?
Click the timer key, there are addition and subtraction keys can be set, the specific I did not use Norit big, do not know, you still consult their customer service department, the instructions should also have.
Q:How the solar panels with the controller
Battery status indication: When the battery voltage is in the normal range, the status indicator (2) is green; if the status indicator is green slow flashing; when the battery voltage drops to undervoltage, the status indicator turns orange; when the battery When the voltage continues to decrease to the overdischarge voltage, the status indicator (2) turns red, and the controller will automatically turn off the output to remind the user to replenish the power in time. When the battery voltage returns to the normal operating range, the output enable action will be automatically enabled and the status indicator (2) will turn green;
