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.


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:




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:The principle of solar controller
The controller is divided into square matrix (series, parallel) and DC-DC conversion (with MPPT and no MPPT). The principle of withdrawal is the controller to detect the voltage of the battery, when the set value to withdraw from the square: parallel type of Chiang out of the square in parallel to the controller on the dummy load; series directly to the square open circuit. DC-DC conversion type: some parameters will be cured to the controller (usually the charging voltage is set to 55.2V), the square output voltage through the converter fixed to the set value to the battery charge; with MPPT with the above function , But also through the internal MPPT module to track the maximum power point of the matrix so that the matrix has been working in the solar cell's maximum operating point.
Q:How to choose a solar controller
The choice of solar street light controller, generally in accordance with the current, and the current mainly depends on the battery power and battery voltage ratio and the load power with the battery voltage ratio, who take those who, such as the load is 60W, battery with 100W, battery Voltage 12V, 60W / 12V = 5A, 100W / 12V = 8.333A, so choose 12V10A solar controller
Q:What is the system voltage of the solar controller?
The system voltage is the voltage you use the battery, such as 12V or 24V. According to your overall configuration, if your battery is a working voltage of 18V, then the system voltage can only use 12V, 36V is used on the 24V.
Q:How to adjust the solar 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 rises to the start point, the controller delay 10 minutes to confirm the closure of the signal after the closure of the output, the load stops working.
Q:Solar water heater all intelligent controller how to install
The controller can also control the electric heating. When the electric heating key is pressed, the controller turns on the power of the electric heater 7 and the electric heater operates until the user specifies the temperature. When the temperature drops below the specified temperature 3-5 degrees, the controller restarts the electric heating and heats the water to the specified temperature. Users can also specify the heating time, at a time, the temperature of the solar water tank can not reach the set temperature, the controller will turn on the electric heater, the water tank to the water set to the temperature so far. The controller also has a protective effect, and when the water level drops to a certain point, the electric heating stops until the water level rises above that point. (Usually 50% of the water level).
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:Solar controller one machine how
Built-in high-precision step-up constant current source, no need to reprovision LED constant current source, can directly drive LED lamp beads, single string up to 18, up to 9 groups in parallel, the output power can reach 160W, to meet all the market LED street lamps;
Q:How does the solar controller set up Sheung Shui?
Solar water, heating is fully automatic operation, so users do not have to do any operation. The user can use the "SET" key to adjust the Beijing time and all-weather timing Sheung Shui, regular heating time, use ← left shift, right shift key to select the adjustment items, use ↑ to rise, ↓ down key to adjust the parameters, press "SET" Sheung Shui, heating, heat preservation, cycle key can start the corresponding function, after starting, Sheung Shui, heating, insulation, cycle icon flashing. The user continues to hold down the "SET" key to restore all parameters of the all-weather mode set by the factory.
Q:A solar controller 12v20A battery 12v 20A Will the need for a few watts of solar panels can be normal charge
Solar controller uses high-speed CPU microprocessor and high-precision A / D analog-to-digital converter, is a computer data acquisition and monitoring and control system. It can collect the working data of the PV station in real time, obtain the working information of the PV station at any time, and accumulate the historical data of the PV station in detail, and provide the accurate and reliable evaluation of the reliability of the PV system design and the reliability of the quality of the inspection system Full basis. In addition, the solar controller also has a serial communication data transmission function, can be a number of photovoltaic systems sub-station for centralized management and remote control.
Q:How to debug a solar street light controller
Pure light control (0): When there is no sunlight, the light intensity drops to the starting point, the controller delay 10 minutes to confirm the start signal, according to the set parameters to open the load, the load began to work; when there is sunlight, light intensity to start Point, the controller delay 10 minutes to confirm the closure of the signal after the closure of the output, the load stops working.
