DC-AC Solar Inverter

Solar power inverter (car power) is a way to convert the DC DC12V and AC220V AC mains the same for general electrical use, is a convenient power adapter.Some users in the country for convenience some of the DC current electrical appliances such as: mobile phones, laptops, PDA, etc. do not use their own in the car with the 220V power supply and coupled with simple adapter plugs directly into cigarette lighter, so that is not right , car battery voltage instability, direct access to electrical power may be destroyed very safe and may significantly affect the electrical service life, because the original manufacturer with the 220V power supply is designed specifically for electrical appliances, has an excellent stability.Almost every vehicle in a foreign country can find a car kit solar inverter, because it’s useful too, with it, your car becomes your home electricity outlet plate, you are free to Use your previous non-use of electrical appliances in the car was.

Office equipment: fax machines, laptop computers, mobile phones, printers and monitors
Household appliances: TVs, VCRs, game consoles, audio, VCD, DVD, and refrigerators, etc.
Outings: outdoor lighting, microwave ovens, cooking, etc.
Outdoor work: power tools, vehicles for assistance, disaster relief, commercial promotions
Entertainment: phone, PDA, digital cameras, digital cameras, batteries, GPS satellite navigation.
 

With solar power inverter, you can use direct current (batteries, switching power supply, fuel cell, etc.) into alternating current for electrical appliances have power to provide stable and reliable protection, such as laptops, mobile phones, handheld PC, digital camera and a variety of instruments ; solar inverter can also supporting the use of the generator can effectively conserve fuel and reduce noise; in wind energy, solar energy, solar inverter is essential. Solar Inverter can also use small cars, ships, portable power devices, in the field to provide AC power.

Solar inverter technology commonly used parameters:

1. The use of solar power inverter environmental conditions, the inverter normal conditions of use: altitude does not exceed 1000m, the air temperature 0 ~ +40 ℃.
2. DC input power conditions, the input DC voltage range: the value of the battery pack rated voltage ± 15%.
3. Rated output voltage, input power conditions specified, the output rated current, the inverter rated output voltage should be. Voltage fluctuation range: single phase 220V ± 5%, three-phase 380 ± 5%.
4. Rated output current, the required output frequency and load power factor, the rated inverter output current should be.
5. Rated output frequency, the required conditions, the fixed frequency inverter rated output frequency is 50Hz: Frequency fluctuation range: 50Hz ± 2%.
6. The largest solar inverter harmonics, sine wave inverter, in the resistive load, the maximum output voltage harmonic content should be ≤ 10%.
7. Solar inverter overload, under specified conditions, in a relatively short period of time, the inverter rated output current capability. Inverter overload capacity should be provided under the load power factor to meet certain requirements.
8. Inverter efficiency at rated output voltage, output, what-flow and under a specified load power factor, active power and the input inverter output active power (or DC power) ratio.
9. Load power factor, power factor inverter allows the load range, the recommended values 0.7-1.0.
10. Asymmetric load, in 10% of the non-symmetric load, fixed frequency three-phase solar inverter output voltage asymmetry should be ≤ 10%.
11. The output voltage of the asymmetry in normal operating conditions, the load of each phase symmetry, asymmetry of output voltage should be ≤ 5%.
12. Starting characteristics, under normal operating conditions, the inverter at full load and no-load operating conditions, should be able to start for 5 times normal.
13. Protection, the inverter should be set: short-circuit protection, over current protection, over voltage, under voltage protection and phase protection.
14. Interference and interference, the inverter should be required under normal operating conditions, the general environment can withstand electromagnetic interference. Anti-jamming performance and the inverter should meet the electromagnetic compatibility standards.
15. Not always operation, monitoring and maintenance of solar inverters, should be ≤ 95db; regular operation, monitoring and maintenance of the inverter, should be ≤ 80db.
16. Shows that there should be exchange of inverter output voltage, output current and output frequency and other parameters of the data, and input electric, power and fault status of the signal display.

In the PV / wind hybrid systems use inverter, first and foremost is to determine the inverter are several main technical parameters: input DC voltage range, such as DC24V, 48V, 110V, 220V, etc.;
Rated output voltage, such as three-phase 380V, single phase or 220V; output voltage waveform, such as sine wave, trapezoidal wave or square wave.
