A voltage converter or transformer is an electrical device that takes power from a wall outlet and increases or decreases energy, so we can use electrical equipment in different regions or countries. Power converters allow you to run your equipment at the same speed as when it was manufactured, allowing you to use your equipment safely and comfortably anywhere in the world. First, knowing that while higher voltages will never damage your device, using underpowered converters can easily damage your device. How do you choose the most suitable voltage converter?

The popularity of ups inverters is on the rise and a large number of homes are switching from traditional generators to household ups inverters. Since the cost of ups inverter is much less than that of generator, switching does make sense. Buying a uninterruptible power supply inverter is a good move. There are various other reasons. This article will list several reasons why it's worth buying.

Currently, the power supply of the machines stops working. The UPS and inverters are used to combine with providing the backup power and you can get lots of electricity outage. However, the important functions of the store the electricity process. The following is about the advantages of ups inverter.

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.

Whether you need to keep the lights on when the power grid is off, or you want to charge your mobile phone while camping, solar generators are a good way to have extra energy on hand. Constant radiation from the sun is converted into electricity through solar panels. By using solar generators, this energy can be stored for future use. This is only one of the many benefits of a solar generator. To learn more about solar generator benefits, check out what’s below to know.

With this year's home order and social distance, we all rely more on the power supply at home. Finding a suitable backup power source for your home is an important safety measure if the power grid fails, breaks down or people are trapped in their homes. Two of the most popular power solutions are solar generators and traditional gas powered generators. Each option has its advantages, but solar generators are more cost-effective, resilient and sustainable than gas generators.

Sea-land breeze is a diurnal local wind that occurs in offshore and coastal areas. Land and sea winds are caused by the temperature difference between land and sea during the alternation of day and night. That is, the temperature over the sea is lower than the land during the day and higher than the land at night. The temperature difference brings about the density and pressure difference of the near-surface atmosphere, and the pressure gradient force pushes the air flow from regions of high pressure (low temperature) to regions of low pressure (high temperature).

Due to wind data is essential for documenting eddies and protecting wind turbines, wind turbines need accurate wind operating information in order to operate safely. 300W wind turbine with low starting wind speed and low running vibration. When the anemometer speed does not change rapidly, such as when the bearing belt is faulty, the eddy current cannot be accurately measured. The turbine control system adjusts the blade spacing and rotor speed separately according to the degree of turbulence in order to protect the blades and drive mechanism from fatigue damage caused by improper use of rotating blades.

Safety rules will guide in making our whole solar system to be well cabled together and having the appropriate and correct size protection devices/fuses, in addition to good labeling and the existing of the operating manuals for all solar system components according to international and local standards.

Net Metering is one of the dominant arrangements the electricity company dealing us in billing when we install our new solar photovoltaic system. Under this arrangement, the electricity generated from the solar inverters and the solar photovoltaic system will go to feed our home (electrical loads) at first, and then the additional excess generated electricity which is not required by our home electrical appliances/loads will be exported to the power grid.

In some kind of solar photo voltaic system called Off Grid system, your solar system will incorporate batteries that can feed your loads with electricity in case of low sun radiation and night time. But such batteries add a significant cost to your solar system, so it is usually recommended to be used in remote areas in where there is No regular electricity supply exists.

The energy metering system is an important component in our solar system, because it tells us how much electricity our solar system generates, how much electricity our electrical appliances and equipment are using and the amount of electricity we are still buying for the power utility or export to the power utility after connecting our solar system to the power grid.

There are many different solar photo-voltaic monitoring systems in the market, and the basic element which doing such monitoring is the solar inverter itself. So, the solar inverter usually comes with some monitoring levels starting from simple convenient level to sophisticated level.

The solar inverter is the main crucial part of our solar photovoltaic system, so we have to take care about all details related to it, like mainly choosing the high quality brand when purchasing, and proper technical installation, etc. One of the important details is: Should we install it inside or outside the home? Where we should install it in our home? And what is the best place?

Actually there are three main types of solar panel in the market, and they differ between each other mainly in 3 parameters: Efficiency, capability to withstand high environment temperature, and capability to deal with diffused sun light.

After installing our new solar photovoltaic system, our electricity consumption from the electric grid may be changed, resulting in new / modified electricity consumption pattern. Also, as a result we may be subjected to a new metering regulations according to our country rules. The question is: Will there be a tariff change due to our new solar system installation? The answer for this question will be provided by your electricity retailer. Moreover, we have to get the answer for this question even before installing our solar panel power inverter, so we can weigh up the dis-advantages and advantages of the new installation before making our decision.

When Solar System company/installer design our solar photo-voltaic array, they specify two standard slopes: The first is the orientation which means the solar panels face direction, whether it will be to North, South, East or West, and the second is tilt angle which means the solar panel angel with horizontal surface "roof angle". Ideally, solar panels should face the south, and the tilt angle should equal to the solar system location latitude, so we can get maximum electricity production from our solar phot-voltaic system.

In grid tie solar photovoltaic system in which the solar inverter output is connected to the AC power grid, there are 2 ways of electrical energy metering scheme: gross metering and net metering. And here we shall discuss the difference in between.

The solar panel efficiency is the ability of the panel to convert sunlight power to usable electrical power, for example, if the solar panel efficiency is 16%, that means only 16% of the sun light hits the panel will be converted to usable electricity. Actually in the market, the average solar panels efficiency ratings vary in the range 15% up to 20%.
