Product Introduction

Solar controller is control device which can control solar panel and transform solar energy into electricity then store to the battery bank. Solar controller is the most important part in offgrid system, whose performance has much effect on life expectancy and operation of the whole system, especially the battery expectancy. 

Application Areas

Standalone Photovoltaic power station

Standalone Domestic household photovoltaic power system

Mobil communication base stations, expressway and other non-residential regions.

Coastal islands, remote mountainous, border posts for regions shortage of or without electricity.

Government demonstration projects, landscape lighting project etc.

Q:Solar panels for solar panels
Cancel the potentiometer to adjust the control set point, and the use of E-side memory records the work of the control point, so that set the digital, eliminating the potential deviation due to potentiometer, temperature drift, so that the control point error reduction accuracy, reliability Factor; use of digital LED display and settings, one-button operation to complete all settings, the use of extremely convenient and intuitive role is to control the work of the entire system, and the battery played a charge protection, over discharge protection role. In the larger temperature difference, the qualified controller should also have the function of temperature compensation. Other additional functions such as light control switch, time control switch should be the option of the controller;
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?
General solar energy is now used LED lights, because the solar power is limited, with LED more power, the general 3, 4 watts when the general lights a 20 watts of brightness.
Q:Solar controller water level display is not correct how to do
Re-adjust the water level to control, choose their own water.
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:How the solar panels with the 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 intensity rises to the starting point, the controller delay 10 minutes to confirm the closure of the signal after the closure of the output, the load to stop working.
Q:What is the use of solar controller
Some controllers also have a negative load power adjustment mode. Explain that the above is based on electricity and photoelectric interiors to describe the street system, but you can make independent of the other system
Q:Solar controller does not heat how to heat
The above heating of the controller is in the absence of the sun and you need to use hot water to add, so that you can use hot and cold weather.
Q:Solar controller red light flashing
Look at the flash of red light shows what is the logo, the general controller should be a bad flash line
Q:How the solar controller wiring,
Carefully follow the instructions on the wiring
