Solar photovoltaic system is a new type of new energy technology, rapid development in recent years, but also to bring a lot of convenience household electricity, solar home has become increasingly popular. Solar panels produce DC electricity. DC power in one direction by moving electrons, created from negative to positive. It is mainly used in batteries, including the use of basic applications, such as flashlights, are also good to use in a short distance.
Most have run on AC power household appliances and electronic equipment. AC power by moving electrons back and forth between negative and positive terminals generate a sine wave created. AC power advantage is that the voltage can be adjusted so that it is easier to move longer distances, which is why its use in the home.
Since the solar panel can produce direct current, an inverter for converting DC into AC power into usable. An inverter to convert DC to AC step to produce a variety of waveforms. The basic square wave inverter, but only a small voltage, so these are just used to run small appliances and light bulbs. If you want to run your coffee pot, this should do fine.
More sophisticated use of the inverter more steps to produce a modified square wave, sine wave or modified, because they can be more generally known, which is an excellent motor, lamps and TV and high power wave Chung, but may cause problems and more sensitive electronic equipment. The solor pv inverter also generates harmonic distortion, resulting in the background hum of audio equipment.
In the off-grid applications, the DC power stored in batteries. The inverter then converts alternating current from the battery into usable electricity. The inverter must be large enough to supply all the appliances and equipment that will run at the same time, and must be able to handle the power surge from clothes and dishwashers, dryers, etc.
And inverter provides power to families in need, any excess electricity fed into the grid. They include sophisticated detection equipment to ensure that they shut down the power grid outage detection, or when workers need to work grid tools.
Works grid tied inverters with battery backup same grid tied inverter, as long as the power grid has to, but if a power outage occurs, they will switch the power supply into the home through the battery. When power returns to normal, the inverter switch back to using the grid, while charging the battery.
As you can see, the inverter is essential, solar panels, if any or all of the electricity comes from. Advances in inverter technology is making all the time, the main drawback is the lack of efficiency, because most of the inverter is only 90-95% efficient operation.
