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.

Grid-tie inverters that are available on the market today use a number of different technologies. The inverters may use the newer high-frequency transformers, conventional low-frequency transformers, or no transformer. Instead of converting direct current directly to 120 or 240 volts AC, high-frequency transformers employ a computerized multi-step process that involves converting the power to high-frequency AC and then back to DC and then to the final AC output voltage.

Historically, there have been concerns about having transformerless electrical systems feed into the public utility grid. The concerns stem from the fact that there is a lack of galvanic isolation between the DC and AC circuits, which could allow the passage of dangerous DC faults to be transmitted to the AC side. Since 2005, the NFPA's NEC allows transformerless (or non-galvanically) inverters. The VDE 0126-1-1 and IEC 6210 also have been amended to allow and define the safety mechanisms needed for such systems. Primarily, residual or ground current detection is used to detect possible fault conditions. Also isolation tests are performed to insure DC to AC separation.

Many solar inverters are designed to be connected to a utility grid, and will not operate when they do not detect the presence of the grid. They contain special circuitry to precisely match the voltage and frequency of the grid.

A charge controller may be used to power DC equipment with solar panels. The charge controller provides a regulated DC output and stores excess energy in a battery as well as monitoring the battery voltage to prevent under/over charging. More expensive units will also perform maximum power point tracking. An inverter can be connected to the output of a charge controller to drive AC loads.
