Power Inverter from DC to AC,dc to ac converter for solar panel

A power inverter, or inverter, is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). It changes DC power from a battery into conventional AC power that you can use to operate all kinds of devices, such as electric lights, kitchen appliances, microwaves, power tools, TVs, radios, computers, to name just a few. Just connect the inverter to a battery, and plug your AC devices into the inverter. Then you will get portable power whenever and wherever you need it.

 

The inverter draws its power from a 12 Volt battery (preferably deep-cycle), or several batteries wired in parallel. The battery will need to be recharged as the power is drawn out of it by the inverter. The battery can be recharged by running the automobile motor or a gas generator or solar panels or wind.

 

 

 

1、High Efficiency and quick start.

 

2、The inverter is safe and dependable for its functions of short-circuit, overload, over voltage, under voltage and over temperature protection.

 

3、The inverter has good physical performance. It adopts aluminum shell good heat dissipation. Hard anodizing technology is applied to deal with the surface. Therefore, the inverter is of good rub resistance.

 

4、The inverter is well-adapted and of good stability.

 

 

Inverter will consume part of the electricity when it is working. Therefore, the input power is supposed to be higher than its output power. The efficiency of inverter is the ratio of output power to input power. If the input power of an inverter is 100W direct current and output power is 90W, then the efficiency is 90％.

 

 

According to the types of power supply, the inverters can be divided into coal power inverter, solar power inverter, wind power inverter and nuclear power inverter. According to the application purpose, the inverters can be divided into independent control inverter and grid-connected inverter. According to the output wave, the inverters can be divided into sine wave inverter and square wave inverter.

 

The sine wave inverter outputs sine wave alternating current. It is better than the output current of power grid because there is no electromagnetic pollution.

 

The square wave inverter outputs square alternating current of poor quality which brings instability to the load and the inverter itself. Besides, the load capacity is equal to 40％-60％ of rated load capacity.

 

In conclusion, the sine wave inverter can output alternating current of high quality which can drive all types of loads. However, the cost is high and the technical requirements is hard to meet. The sine wave inverter can meet most of our power demand. The high efficiency, low noise and reasonable price make it the mainstream product in the market. The manufacturing technology is backward and the square wave inverter adopts simple multivibrator. This type of inverter will gradually be phased out.

 

 

1、The chosen battery voltage value is supposed to be the same as the input voltage value of inverter. For example, 12V inverter should be matched with 12V battery.

 

2、The output efficiency of inverter is supposed to be higher than the service efficiency of appliances, especially those with high start-up efficiency, such as air-conditioner and refrigerator.

 

3、The distance from the inverter to surrounding objects should be more than 20cm. Besides, it should be far away from flammable and explosive articles. Please do not place other objects on the machine.

 

4、The inverter should be placed in a ventilated and dry place so that it can be protected from the rain. The working environment temperature is supposed to be less than 40℃.

 

5、When the inverter works, it can not be charged.

 

6、Please restart the inverter after 5 seconds.

 

7、Please use the dry cloth or anti-static cloth to clean the inverter.

 

8、The inverter should be properly grounded.

 

9、For the sake of safety, users are forbidden to open the case and operate.

 

10、If there is mechanical fault, do not continue to operate and use. The input and output should be cut off immediately. The inverter should be checked and repaired by qualified maintenance personnel or maintenance organizations.

 

11、When connecting the inverter to battery, make sure that there are no metal objects on your hands. Otherwise, there will be short-circuit and people may be burned.
