1, Product  desciption

Inverter circuits designed to produce a variable output voltage range are often used within motor speed controllers.

The DC power for the inverter section can be derived from a normal AC wall outlet or some other source. Control and feedback circuitry is used to adjust the final output of the inverter section which will ultimately determine the speed of the motor operating under its mechanical load.

Motor speed control needs are numerous and include things like: industrial motor driven equipment, electric vehicles, rail transport systems, and power tools. (See related: variable-frequency drive ) Switching states are developed for positive, negative and zero voltages as per the patterns given in the switching Table.

The generated gate pulses are given to each switch in accordance with the developed pattern and thus the output is obtained.

Solar power is energy from the sun. "Solar" is the Latin word for "sun" and
And Powerful source of energy. Without it, there will be no life.
Solar energy is considered as a serious source of energy for many years
of the vast amounts of energy that is made freely available, if harnessed by modern technology.

A magnifying glass can be used to heat up a small amount of water.
The short piece of copper tube is sealed at one end and filled with water.
And magnifying glass is then used to warm up the pipe.
Using more than one magnifying glass will increase the temperature more rapidly. 


2, Features of  the  product


Inverters convert low frequency main AC power to higher frequency for use in induction heating.

To do this, AC power is first rectified to provide DC power. The inverter then changes the DC power to high frequency AC power. Due to the reduction in the number of DC Sources employed, the structure becomes more reliable and the output voltage has higher resolution due to an increase in the number of steps so that the reference sinusoidal voltage can be better achieved.

This configuration has recently become very popular in AC power supply and adjustable speed drive applications. This new inverter can avoid extra clamping diodes or voltage balancing capacitors. There are three kinds of level shifted modulation techniques, namely: 1,High and stable conversion efficienly based on over 4 years professional experience

2 ,High reliability with guaranteed +/-10% output power tolerance

3,Proven materials,tempered front glass,and a sturdy anodized aluminum frame allow modules to operate reliably in multiple mountily configurations

4,Combination of high efficicncy and attractive appearance


The first thing to figure out is the length of road in need of street lights.

This can be a small entrance road only a couple hundred of feet long to miles of streets through an area. Does the area currently have any type of lighting available.

 What is the reason for needing street lights in this area


Is the electrical grid already nearby or would you need to call in the power company to bring in electrical lines.

 If the electric needs to be brought to the area, how much is this going to cost? Depending on how far the grid electric is from the location of the needed lighting, this can be quite expensive.

 How much lighting is needed on the street? Do the lights need to be dark sky compliant.

Do the street lights need to run from dusk to dawn or for only a specified number of hours at night.

Are the street lights able to dim in the middle of the night and still provide enough lighting.

These questions need to be answered before you can decide on how many lights you will need to complete the project.

Q:What is good for solar lights?
Under normal circumstances is south by west point, because it can get more sufficient sunshine, of course, also has a relationship with the angle, so according to the specific installation location to configure the.
Q:What are the advantages of solar led street light?
And in the winter only half, cloudy day is generally only about 1/5, so that the energy density is very low. Therefore, in the use of solar energy, you want to get a certain conversion power, often need a considerable area of ​​a collection and conversion equipment, cost higher.
Q:What are the components of the solar street light
Utilizing solar power, unparalleled cleanliness, high safety, relatively extensive and sufficient energy, long life and maintenance-free benefits from other conventional sources of energy, photovoltaic energy is considered to be the twenty-first century The most important new energy.
Q:What are the features and advantages of solar street lights?
with ordinary light, there are indeed many incomparable advantages. First of all, he is not ditching embedding, the engineering quantity is relatively small, as long as the installation of a cement base, with stainless steel screws fixed on the line. 
Q:What are the problems of LED solar lights such as high damage rate and low brightness
The utilization of solar energy itself is not high, only 15%-17%. An ordinary 100WLED street lamp cost even if 2000 yuan, then with the wind and solar complementary system is estimated to be ten thousand yuan. 
Q:What is the working principle of solar lighting?
The use of photovoltaic effect of the principle of solar solar panels solar solar panels to receive solar radiation and converted into electrical energy output, through the charge and discharge controller stored in the battery, the night when the illumination gradually reduced to 10lux or so, the solar panel open circuit voltage 4.5V
Q:Solar lights do not always open but charge every day, the battery will be bad
Working principle: the use of photovoltaic effect of the principle of solar cells, solar panels during the day to receive solar radiation and converted into electrical energy output, through the charge and discharge controller stored in the battery, the night when the illumination gradually reduced to about 101ux, solar panels
Q:How to handmade a small solar light
power system can do what, as long as the power enough 2 solar water heaters are basically two types, boring drying and tube A boring drying tube type solar water heater simple, find a container, such as large gasoline barrels, then the water and outlet pipes, put the sun a good sun, There is hot water.
Q:How long can a solar street light be used?
small plant life shorter, to 3 years 5 years the actual capacity of the battery than the initial capacity to reduce a lot, replace a battery price Not too high, then where the purchase can be replaced. The fourth controller, the controller price is relatively low more than 100 dollars, the service life of 5 years or so, and finally part of the poles, most companies are currently available for you are hot-dip galvanized spray poles, by 10,20 Year will not be damaged.
Q:Can a solar-charged watch be filled with a fluorescent lamp?
In short, the output current when the fluorescent lamp is very small, unless the load current is very small appliances, or nothing meaningful.
