The principle of the PWM controller is based on the fact that narrow pulses with equal impulse but different shapes have the same effect when applied to the link with inertia. PWM control principle: divide the waveform into 6 equal parts, which can be equivalently replaced by these 6 square waves. There are many classification methods of pulse width modulation, such as single polarity and bipolarity, synchronous and asynchronous, rectangular wave modulation and sine wave modulation, and so on.
Centrifugal pump refers to the centrifugal force produced when the impeller rotates to transport the liquid pump. Centrifugal pump is the use of impeller rotation and make the water centrifugal movement to work. We should not only know what is centrifugal pump, but also pay attention to the main points when choosing products. In this article, Inverter.com will show you the steps to choose a centrifugal pump.
As the solar panel is always made of waterproof materials, and uses a good sealant for its internal solar cells and wiring, there is no worry when we see rains drop on solar panels for long time. The damage which may be happened due to water is very rare. Actually the solar panel is designed to work effectively when it is rained on for even decades.
It's an electrical equipment that provides us a feedback about the electrical energy usage on our home or building, it displays how much energy is used, and the cost of used energy. Many types of such monitors are existing in the market with different capabilities. Actually there are many benefits we harvest when installing such energy monitoring devices, Here we will introduce some of these benefits as following.
Hiring a cleaning service is the easiest way to clean your solar panels, moreover using the cleaning service provided to you from your original solar panels provider will be better, more economical, and very easy as well. Most of solar panels suppliers provide the cleaning service fees as a part of their installation package, and that should be listed in the contract signed between the solar panels supplier and the solar system owner.
What is the Solar Watch?
-Wednesday, November 9, 2022
In order to save our planet from pollution, we proceed different ways and techniques, like lights turning off when Not needed, water turning off when Not needed, keeping garden and planets, and using different kinds of renewable energy sources, like wind energy, nuclear energy, and solar energy.
Our target of installing the solar system is to harvest as much electrical energy as possible to power and run our home appliances, and electronic equipment. However, to do so, there are some factors affecting how much electricity we shall gain, like; solar panels tilt angle, solar panels sun directions, location, surrounding climate, location latitude, and the season.
Sine wave inverter is an electric energy conversion device that converts direct current into alternating current. It completes the inverter task by conducting and turning off power semiconductor devices according to specific rules. With the rapid development of power electronics technology and the improvement of inverter control performance requirements in various industries, sine wave inverter has also been rapidly developed. In this article, we mainly talk about the development direction of sine wave inverter.
What is PV Power?
-Friday, October 28, 2022
The electricity produced by PV modules is direct current, which can be converted into alternating current by inverters and then used, or all of it can be delivered to the public grid. From another point of view, the electricity generated by the PV power generation system can be used immediately, or the electricity can be stored in storage devices such as batteries and released for use at any time as needed.
Solar photovoltaic system consists of solar cell, solar controller and battery. Solar panel is the core part of solar photovoltaic system, the role of solar panel is to convert the sun's light energy into electric energy, output direct current into storage battery. Photovoltaics is an electronic process that occurs naturally in semiconductor materials. When sunlight hits semiconductor materials, electrons are released and can travel through circuits, producing electricity that powers our electrical devices.
Watt is the power unit, we use it in electrical circuit, and electricity mechanism. A simple example to clear the meaning; With the higher number of watts of electrical lamp, the brighter light it produces. So, with the higher number of solar panel watts, the more electrical energy it will be able to generate.
The grid tied inverter is generally used in the system of large-scale photovoltaic power stations. Many parallel photovoltaic strings are connected to the DC input end of the same centralized inverter. Generally, 3 phase IGBT power modules with high power are used, and the power is relatively high. Small uses field effect transistors, while using a DSP conversion controller to improve the quality of the power produced, making it very close to a sine wave current.
A voltage converter is a static electrical device that converts an AC voltage of a certain value into a voltage with the same frequency but different values. Transformers are made of two or more sets of coils wound on the same bobbin or on the same iron core.
A wind turbine is a power machine that converts wind energy into mechanical work. Generally speaking, it is a thermal energy generator that uses the sun's micro-heat source and the atmosphere as the working medium. Wind turbines use natural energy, which is much better than diesel power generation.
The solar generator generates electricity by direct sunlight on the solar panel, and charges the battery, which can supply power for DC energy-saving lamps, tape recorders, TVs, DVDs, satellite TV receivers and other products. It has protection functions, including overcharge, over discharge, short circuit, temperature compensation and reverse battery connection. The solar generator can provide 12V DC and 220V AC output.
What is UPS?
-Tuesday, December 21, 2021
UPS means uninterruptible power supply that contains energy storage devices. It is mainly used to provide uninterrupted power supply to some equipment which requires high stability of power supply.
Types of Wind Energy
-Tuesday, October 12, 2021
The wind is a renewable energy source caused by uneven heating on the earth's surfaces by the sun. Wind power refers to converting the kinetic energy of wind into electricity. It is a kind of clean and pollution-free renewable energy, has been used by people in the early time, mainly through the windmill to pump water, grinding surface and so on. Using wind power to generate electricity is environmentally friendly, and the wind energy accumulation is huge.
What is PV Combiner Box?
-Friday, September 24, 2021
As we all know, the current urban landscape is seriously polluted. In addition, the amount of natural resources is drying up. Although it is considered that sustainable resources in the world today are better than exhausted resources, the current resources are still insufficient to meet the necessary quotas of the entire society. Like sun, water, and wind into energy to solve this problem. To convert and make good use of solar energy, the “Solar Combiner box” has been invented.
What is Solar Power System?
-Monday, September 13, 2021
All solar power systems work on the same basic principles. Solar panels first use the photovoltaic (PV) effect to convert solar energy or sunlight into direct current electricity. Direct current can then be stored in batteries or converted to alternating current through solar inverters to run household appliances. Depending on the type of system, excess solar energy can be fed into the grid to earn credits or stored in a variety of different battery storage systems.
Its easier for solar panels system to be used to charge electric car batteries while its parked in your garage, and/or to run the electric car directly instead of connected to the power grid for synchronization (grid tie solar system). The solar system can be used not for only the car, but for train, bus and tram, and its highly expected that such electric vehicle will be one of the most preferred transport method in the coming few years, it will be widely used in homes and business. And the price of solar panels is also very cheap, almost every household can use it.
