Q:What is the meaning of the DC load above the solar controller?
Solar power systems are generally DC storage, of course, there are grid-connected power generation, the output is AC, but this system is still relatively small in the country, especially for some small systems. If it is a solar street light system,
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: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:Solar controller use
The controller as a core component of solar energy must be a reliable product, otherwise no matter how good the solar system can not play its due role.
Q:What is the use of solar controller
Power adjustment function
Q:Solar controller one machine how
4LED display status, dual digital display mode of operation (a key operation intuitive, with power saving mode); can also be compatible with 12V system and 24V system (fully compatible) LED lamp operating current size, that is, the first period of work adjustable power ; The second time period, the third time period the power size adjustable, adjustable range of 10% -90%; the first time period, the second time period, the third time period, before dawn lights time adjustable; Tune, that is, after a few days after the delay in time to turn on the lights.
Q:What brand of solar controller is good
Do you ask the controller for photovoltaic power generation?
Q:A solar controller 12v20A battery 12v 20A Will the need for a few watts of solar panels can be normal charge
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.
