Investment in renewable energies such as wind power and biofuels leapt to a record $100 billion in 2006 and worries about global warming are likely to sustain the boom, a UN report said . Among this fund, almost 10 percent of there 2006 inverstments were in China. Its forecasted that by 2020, more than $40bn will be invested on slar sector , acocunt for about 16% of the total RE inverstment in China. power inverter

solar inverters
Direct current is used to charge batteries, and in nearly all electronic systems as the power supply.
Very large quantities of direct-current power are used in production of aluminum and other electrochemical processes. Direct current is used for some railway propulsion, especially in urban areas. High voltage direct current is used to transmit large amounts of power from remote generation sites or to interconnect alternating current power grids

switching device
The electromechanical version of the switching device includes two stationary contacts and a spring supported moving contact. The spring holds the movable contact against one of the stationary contacts and an electromagnet pulls the movable contact to the opposite stationary contact. The current in the electromagnet is interrupted by the action of the switch so that the switch continually switches rapidly back and forth. This type of electromechanical inverter switch, called a vibrator or buzzer, was once used in vacuum tube automobile radios. A similar mechanism has been used in door bells, buzzers and tattoo guns.

functions --- inverter
An inverter changes direct current “DC” energy that solar panels produce into alternating current or “AC” energy that your t.v. and computer uses. In fact, unless you’re out in the middle of nowhere and off the grid, anything you plug is going to require AC energy. So the inverter is necessary for solar systems
inverter
We can expect to see and hear even more about inverters as the demand for power increases because of their ability to save fuel and keep drivers out of the hot seat in no-idle zones.

inverter
Power inverters are great for camping at parks that do not provide electricity. The toaster, blender, and boom box can all still be used. On your boat you can plug in the digital movie camera to capture those great water-skiing videos you might have missed after the camera's battery ran low! find more on www.siminvent.com

car inverters
Car inverter is a kind of work in the high-current, high-frequency environment of power products, the potential failure rate quite high. Therefore, consumers must be careful when buying. First of all, from the inverter output waveform on the election, it is best not to less than the quasi-sine wave; Secondly, the inverter must have a complete circuit protection functions; third, manufacturers have a good after-sales service commitments; fourth, circuit, and products over a period of test of time.

inverter efficiency
Inverter input power is higher than its output power. The efficiency of inverter that is inverter input power and output power ratio. If a Simin inverter DC input of 100 watts, the output of 90 watts of alternating current, then it's efficiency is 90%.
