First half of 2011, market development of solar inverter as expected, but showed sluggish situation. Suggesting the possible for two reasons: first, in 2010 Q2 to Q3 market demand, so that a large number of repeat customers orders, which led to excessive production of 1000w with charger inverter main reason, but also the start of the fourth quarter of 2010, the solar inverter the stock continues to climb. To the first half of 2011, distributors are still trying to clear the 2010 inventory dilemma. Second, the cost of solar energy subsidies continue to reduce the major European markets, resulting in a substantial decline in end-market demand, but also to relative demand for solar inverter greatly reduced.

From the current development of the market, it can be observed five trends of solar inverter:

• (3) requires a wide input voltage range of adaptation
Since the terminal voltage of the solar cell with the load and sunlight intensity changes. Particularly when the aging battery terminal voltage variation range is large, such as a 12V battery, the terminal voltage between 10V ~ 16V may change, which requires the 4000w charge inverter to ensure the normal work in a wide DC input voltage range .

Such inverter output voltage waveform is a stepped wave. Inverters achieve stair-step output also has a variety of different lines. The number of stairs output waveform varies greatly.
Advantages step wave inverters are: wave output waveform example, a significant improvement in reducing high harmonic content, when the ladder to reach 17 or more quasi-sine wave output waveform can be achieved, when using transformerless output high overall efficiency .
The disadvantage is that the ladder wave superimposed line use more power switches, which form some lines also require multiple sets of DC power input. This gives the PV array wiring and balanced grouping and rechargeable battery are in trouble. Further staircase voltage radio communications equipment and some are still some high-frequency interference.

Then let the pulse wave formed by a simple sinusoidal filter.

Solar inverter design

Solar 3000w home inverter is now widely used, for those who can not support themselves national energy, solar energy and other alternative energy sources has indisputable advantages, we can help them to reduce fossil fuel consumption and achieve energy independence purposes. Replace fossil fuel energy with alternative energy systems will have a significant impact on the global economy and human life. But the problem is the cost of the cost of alternative energy generation with fossil fuel generation to be similar or less, in order to truly reduce oil consumption.
In the development of solar technology, engineers put much attention has been placed on how to improve the efficiency of photovoltaic cells. But another important issue can not be ignored is how to design the direct current generated by the battery into alternating current circuits. In order to compete with the cost of power generation burning coal, oil and other fossil fuels, engineers every one percentage point increase best power inverter efficiency efforts are very important.
Some solar energy conversion system manufacturers to battery power inverter conversion efficiency from 92% to 96%, so their chances of success in the market will increase. One way is to design transformerless DC / DC converter. In the conversion system, the energy loss caused by the transformer is approximately 2% to 3%. So we must use higher voltage transistors.

Brief sine wave inverter

Inverters have square wave inverter and sine wave inverter two categories, square wave inverter although single-cylinder structure, low cost, but due to harmonics too, is not suitable for inductive, capacitive circuit work, and sine wave inverter on the market price is relatively high, so some users difficult to accept, thus limiting its promotion and application. A brief introduction and practical 600w car inverter.
Sinusoidal pulse modulation Solar power inverters is the key, they all require a sine wave generator, use it to generate the sine wave and triangular wave (sawtooth) were compared realize sine wave modulation. Many ways and means to generate a sine wave. Methods commonly employed analog and digital two, through a variety of different ways to achieve. As with a filter circuit with a sine wave oscillator generator and the positive feedback amplifier circuit, which is the most common classic circuit, but the adjustment is more complex, frequency accuracy is not high. There are other methods used to generate a sine wave function generator circuit. With large-scale ASIC and MCU constituted sinusoidal pulse width modulation circuit. Using EPROM and D / A converter reference sinusoidal voltage generation is a common method. DSP processors with high-speed data is the latest of a pulse width modulation method, the introduction of computer technology, we need to increase the number of software development and design work, despite the complexity and cost of the circuit coefficient has increased, but it really is great A good design approach capacity 6000w power inverter.

The development prospects of solar inverter uses and processes

Solar AC power generation system consists of solar panels, charge controllers, inverters and batteries composed. Mainly composed of electronic components, it does not involve machinery parts, thus generating equipment is extremely refined, reliable, stable, long life, easy installation and maintenance. Compared with the conventional thermal power system, solar power system in addition to polluting emissions, but also has short construction period and can be used roofing advantage. Wherein the with bypass inverter is a key component of the entire solar system. Because of the direct solar energy output are generally 12VDC, 24VDC, 48VDC. If you want to 220VAC to provide electrical power, solar power system needs to be issued by the DC energy into AC power, this time on the need to use an inverter. In addition, it can be a variable DC output of photovoltaic cells to convert into a clean sinusoidal current at 50 or 60Hz, it is also ideal for providing power to the commercial power grid or local grid. With the development of the solar PV market, solar inverter market will inevitably bring a new spring.
Generally speaking, there are step-up transformer and two types of isolation transformer is applied in the 5000w inverter charger electronic transformers. Since the input DC voltage than AC output voltage level is higher, but the solar panels provide input source voltage is usually not so high, so the system to the AC output side of the step-up transformers to boost voltage. At the same time, both sides need to isolate the circuit transformer isolation to prevent flow AC DC side, improved circuit protection, but also increase the safety of users.
Power inverter can be divided by converting frequency conversion and high-frequency transformation. Frequency transformation is the use of discrete devices or manifold generate 50Hz square wave signal, and then use the signal to push the power switch, the use of frequency step-up transformer to generate 220V AC. As a result of frequency transformer, bulky, heavy, high prices, currently used in large-scale solar photovoltaic power plants. But as the technology matures and the magnetic power MOSFET improving the quality, high-frequency inverter transform it to market. High-frequency 12v car inverter is converted by high-frequency DC / DC conversion technology, the first low-voltage DC power to high-frequency low-voltage AC, after the pulse transformer and then rectified high voltage DC boost.

The inverter schematics and principles explain

The inverter is a direct current energy (battery, battery) into alternating current (typically 220 volts 50HZ sine wave or square wave) devices. The most common emergency power, usually the bottle is inverted into 220V DC communication. Simply put, the 4000w solar inverter is a kind of direct current into alternating current devices.
Whether in remote villages or the wild need or emergency power, the inverter is a very good choice. More common is the engine room of the UPS power will be used, when a sudden power failure, UPS can reverse into a DC battery Reid exchange for computer use, to prevent data due to sudden power loss caused problems. Able to provide uninterrupted power supply, it has a certain security and reliability, stability. The 1000w charger inverter can also be supporting the use of the generator can effectively save fuel, reduce noise, wind energy, solar energy, the inverter is essential. The Pure sine wave power inverter can also use small cars, boats, portable AC power supply equipment in the field.

12v power inverter

Two products in high demand — the 8000 and 12 volt power inverters by AIMS Power — have been rethought to meet industry needs with a more compact, user-friendly design.

The body of AIMS Power’s new 8000w home inverter is half the weight of the old, 21 pounds as opposed to 42, and its frame is also half the size, which makes it applicable to a more diverse range of jobs.

The new 10000 watt inverter is also two times lighter and smaller than any other inverter in its class available for sale online or in stores today.

“We sold a lot of the old models, but they were so big that our customers would basically have to create another compartment outside their power room in order to make it fit,” manager of power inverter, Michael Shepherd said. “We will no longer carry the old version because this one is just better in every way for our customers.”

Other upgrades include: 1, a redesign of the inverters’ ac outlets, which were converted from a cluster to a strip layout to improve functionality when using abnormally shaped plugs; 2, an improved terminal block, which ensures that the inverters put out the max power promised (8000 and 10000 watts); 3, DC inputs that are simplified to one positive and negative, rather than four of each, making for an easier install; and 4, a single fan system, as opposed to a dual, which makes the inverters much more quiet during use and still performs the cooling duty just as well.

Another big advantage to these high powered inverters is the capability to run them off of most vehicles’ standard power systems at 12 volts. This is uncommon amongst inverters with wattage capacities above 8000, making these inverters attractive to mobile business owners or businesses that need reliable mobile power where it otherwise wouldn’t be available.

3000 watt power inverters How to choose the correct ups power inverter mainly pay attention to the following points.

1, the rated output voltage: within a predetermined fluctuation range of the input DC voltage is allowed, it means that the rated voltage of the inverter should be output. Off grid inverter‍ The stability of rated output voltage accuracy is generally defined as follows: In steady-state operation, the voltage fluctuation range should be a limit, such as the deviation does not exceed the rating of ± 3% or ± 5%. Under load mutations or other interfering factors affecting the dynamics of the output voltage deviation should not exceed the rating of ± 8% or ± 10%. 

2, the output voltage imbalance: Under normal operating conditions, the inverter output phase voltage unbalance (reverse component of the ratio of positive sequence component) should not exceed a specified value, usually expressed in% as 5 % or 8%. 

3, the output voltage waveform distortion: battery power inverter‍ When the inverter output voltage is sinusoidal, shall specify the maximum allowable waveform distortion (or harmonic content). Usually to a total distortion of the output voltage waveform that its value should not exceed 5% (10% single phase output enable). 

4, rated output frequency of the inverter output AC voltage frequency should be a relatively stable value, usually frequency 50Hz. Under normal operating conditions the deviation should be within ± 1%. 

5, the load power factor: the ability to characterize the capacitive load inverter with inductive load or. vehicle power inverters‍ In the sine condition, the load power factor of 0.7 to 0.9 (hysteresis), the rating is 0.9.

6000 watt power inverters Car charger safe?

Car charger as a power outlet to charge the phone directly with a car cigarette lighter. Due to the low voltage provided by the automobile, so the car charger just to have 1500w off grid inverter‍ internal overload protection circuit can be. Front-end design car charger socket has a fuse, overload protection circuit when the current exceeds a tolerable level, the fuse blows immediately, play a protective role. Of course, compared with an optional travel charger, car charger when purchasing the addition of an interface to determine, with the car's plug should be firmly connected to the car cigarette lighter plug. Now appeared on the market a variety of feature set one car charger, such as Pu Sanofi PFM-001 audio transmitter car charger, car charger not only has the basic functions, but can audio playback devices (such as mobile phones, 5000w pure sine wave inverter‍ MP3, etc.) music filling in the form is sent via FM car to car radios, car stereos by their play out.

5000 watt power inverters In the case of switching off the engine car inverter you can use

Can. 350 watts or less when using low-power appliances, general car AC power inverters ‍battery can provide power for 30-60 minutes turn off the engine in case, if you use only one laptop consumes 50-60 watts, time will have to grow much. Our quasi-sine wave inverter equipped with undervoltage warning and undervoltage protection circuit, when the prolonged use of the battery voltage drops to 10 volts lead, undervoltage protection circuit is activated, the output voltage is cut off and the police to prevent the battery because voltage is too low to start the engine of the accident. solar inverters‍ Therefore, the user can safely use the inverter under the engine off state.

6000 watt power inverters What is the risk of using an inverter

From the car battery to the inverter input of a piece of wire which 12v pure sine wave inverter‍ carries a very large current, because the poor quality of the wire if the wire too small or copper heat load exceeded even eventually lead to a fire, will lead to a serious accident. Thus, in the course of the inverter must battery inverter charger‍ be operated in strict accordance with the user manual.

8000 watt power inverters How is the battery is equipped with a suitable inverter?

If the specifications of the battery is 12 V, 50 Ah, we multiply by 12 volt 50 A, the output power of the battery obtained is 600 watts. If the inverter efficiency is 90%, then 90% then we Off grid inverter‍ multiply 600 watts, 540 watts obtained. This means that you can push a piece of battery output power up to 540 watts inverter. Of course, you can also take the "one step" type of procurement method, which is to present its own regardless of the specifications of the car with the battery, and buy a power output of 800 watt inverter. Then, the first piece of the battery within the allowable range of immediate use, such as the future for a greater use of the car before full power. Finally, do not ask for power inverters, for example, 100 watts is enough, then you can buy a small power inverter. Moreover, when determining the power of the inverter, there is an important principle that when using an inverter, not long-term operation at full load, which would significantly shorten the life of the inverter while the inverter failure rate is significantly rise. We strongly recommend that users, it is best to 12v pure sine wave inverter‍ use an inverter in not more than 85% of the rated power of the state.

4000 watt power inverters How to choose inverter products?

 Car inverter is a work in high-current, high-frequency environment power products, the potential failure rate is very high. Therefore, consumers must be careful when buying. First, 2000w pure isne wave power inverter‍ from the inverter output waveform selected, preferably not less than quasi-sine wave; secondly, to have a complete circuit of the inverter protective function; Third, manufacturers have a good after-sales service commitment; fourth, circuits and products have been tested over time. 

Inverter, inverter device must be composed of a thing to so called, the difference between him and the transformer directly, that is, he can achieve a DC input and output AC, working principle and switching power supplies the same, but the oscillation frequency in within a certain range, for example, if the frequency is 50HZ, output was AC 50HZ. The inverter frequency can be changed in the device. 

Transformers generally refers to a device-specific frequency Off grid inverter‍ bands, such as frequency transformer, the transformer is that we usually see, they both inputs and outputs must be within a certain range, for example, can work within the 40-60HZ range.

5000 watt power inverters Inverters and inverter

The inverter is VFD / VVVF the Chinese translation. 

Inverter with integrated high voltage power 1000w charger inverter‍ transistor technology and electronic control technology, an independent transmission components. 

Effect is to change the frequency of the AC power frequency and amplitude of the motor, thereby changing the magnetic field of its movement cycle, to control the motor speed purposes. 

The inverter makes simplify complex speed control with inverter + AC squirrel cage induction motor combination can replace most of the original work done by a DC motor, reducing the volume and reduce the maintenance rate, so drive technology development to a new stage. 

Unlike the entry drive with said anti-inverter, inverter, commutator. Not only to DC power inverter to AC power inverter, more continuous need to first industrial inverters‍ rectified AC power to DC power. 

Simply put, the inverter output is only part of the drive.‍

3000 watt power inverters Daily use of the inverter

1. 220V power inverter on the car obtained is 220V 50HZ, the high point of the sine wave, square wave is generally cheaper for. 

With the kind of sine wave power outlet and then, is industrial inverters‍ the same, but in fact, the square wave can also be used, but if there are fans and other electrical equipment used, there will be some noise, the reason for using a square wave, because This modulation is relatively low cost. In general, this car inverter, 500 watts maximum power, but air conditioning is generally more than 700 watts, and that you really want on your home air conditioning loading? Car air-conditioning, including those coaches are allowing the engine to drive the compressor directly, not electricity, if the middle one more electricity conversion process, the loss is even greater. And not good equipment, might as well use the car air conditioning. 

2 pick notebook, TV, CD or something, just use the rated power under his, no problem but note that he is connected to the car battery, although he usually 11V power off automatically to protect avoid low voltage lead car does not start, but still not suitable in the case of the engine is not running with, so Off grid inverters‍ if the load is relatively large, it is recommended to start the engine. If it is no problem to charge the phone down. 

3. Electric car, there is a place called DC-DC module, he also called DC converters, this module input 48V, output 12V, then you just buy a car inverter 12V input can be used. Of course, if you can buy a better 48V input inverter, it is estimated that difficult to buy Moreover, this module can only provide general 5A current, but up to 10A, but also with what the lights, so it is easy to overload, recommended, if you can, buy a DC converters, this converter dedicated to you that the inverter, and then only if the DC converter to provide 5A, then the inverter input should be less than 5A, otherwise it may damage the module Of course there are some current DC converter is great, if you do not repair the place, can go to some electrical repair shop or ask them to give you into a large current, or more DC converters can be connected in parallel, in short, Do not let him overload can be. 

4 In the current urban rail vehicles have a vvvf traction inverter, inverter transformer used in the train pulling high pressure (typically dc750V or DC1500V) into three-phase power supply frequency and voltage adjustable electric traction motivation to use the train during braking can drive traction inertia 2000w pure isne wave power inverter‍ phase energy emitted by motor rotation is converted to direct current is fed back to the grid or consumed by the energy consumption of the module.

6000 watt power inverters Inverter related terms

Inductive load layman's terms, that is, the application of electromagnetic induction principle of making high-power electrical products, such as motors, compressors, relays, etc.. solar power inverter‍ These products need when starting a ratio to maintain normal operation (about 5-7 times) required a much larger current starting current. For example, a refrigerator power consumption during normal operation of about 150 watts, its starting power up to 1000 watts or more. In addition, due to the inductive load in an instant power or disconnect the power supply, will produce back-EMF voltage, peak voltage of this inverter can withstand far greater than the voltage value, it is easy to cause instantaneous inverter overload affect the service life of the inverter. Thus, higher electrical power supply waveform such requirements. 

Quasi-sine wave is also divided into several quasi-sine wave, square wave from almost the same square wave to sine wave closer rounded trapezoidal wave. We discuss here only a square wave, waveform which is currently the most commercially available high-frequency inverter can provide. Such quasi-sine with bypass pure sine wave inverter‍ wave inverter can be used in notebook computers, televisions, modular stereos, camcorders, digital cameras, printers, various chargers, PDAs, game consoles, DVD players, mobile DVD, home for treatment, etc. , the larger the inverter output power can also be used in small electric appliances such as hair dryer, electric cup, kitchen appliances and so on. But for inductive load class appliances such as refrigerators, electric drills, etc. are not prolonged use of quasi-sine wave inverter power supply. Otherwise, it may cause damage or shorten the life expectancy of the inverter and related electrical products. If you must use an inductive load, suggested the use of reserve power larger quasi-sine wave inverter, as the site offers large peak power inverter. Here, the focus here on quasi-sine wave inverter used in TV (traditional display class) examples. TV inverter has the following three requirements: First, the TV in the boot, degaussing circuit for electricity demand has great moments, so the peak power inverter demanding. For example, a 25-inch digital TV, the power consumption under normal operating conditions is about 80 watts, while the boot instantly power up to 1450 watts. Second, because the television field frequency equal to the frequency of the AC power, the AC inverter output frequency must be accurate. Third, the inverter should not interfere with the TV. Even if it can satisfy the above three conditions, the TV when using quasi-sine wave AC power, the screen will still have a few fixed interference pattern, the color will be slightly greenish (when using the old-fashioned TV, cast the situation is more serious), but the other is no different. 

Continuous output power, peak power output of some use electrical motors or tools, such as refrigerators, washing machines, drills, etc., in an instant startup requires a lot of current to drive, once started successfully, only a small current to maintain its normal operation. Therefore, the inverter, it will DC AC inverter‍ have the concept of continuous output power and peak power output. Continuous output power that is rated output power; generally peak output power of 2 times the rated output power. It must be emphasized, some appliances, such as air conditioners, refrigerators and other start-up current is equivalent to 3-7 times its normal operating current. Therefore, only to meet peak electrical power inverter starts to work properly.

6000 watt power inverters Role of the inverter

By the wave nature of the main points chord two categories, one is a sine wave inverter, and the other is a square wave inverter. Sine wave inverter output power is the same 1500w off grid inverter‍ as we use every day or even better sine wave AC power because it does not exist in the electromagnetic pollution. The square wave output of the inverter is the poor quality of the square wave alternating current, the positive maximum to the negative maximum value to almost simultaneously generated, so resulting in a dramatic effect on the instability of the inverter and the load itself. At the same time, its load capacity is poor, only 40-60% of the rated load, not with inductive load (explained in detail below article). If the load carried by large, square-wave current third harmonic components contained enable capacitive currents flowing into the load increases, and in severe damage to the load of the power supply filter capacitor. For the above disadvantages, in recent years a quasi-sine wave (or modified sine wave, modified sine wave, sine-wave, etc.) of the inverter, the output waveform from the positive maximum to a negative maximum time between intervals, using the results improved, but is still 12V inverter charger‍ quasi-sine wave by the broken line, belonging to the scope of the square wave, continuous bad. In conclusion, the sine wave inverter providing high-quality alternating current, can bring any kind of load, but the technical requirements and costs are high. Quasi-sine wave inverter can meet most of our electricity demand, high efficiency, low noise, moderate prices, and thus become the market mainstream products. Square wave inverters produced using simple multivibrator, which belongs to the level of technology in the 1950s, will gradually withdraw from the market. 

According to send power inverter, divided into coal inverter, solar inverter, wind inverter, nuclear power inverter. Depending on the application, divided into independent control of the inverter and inverter. At present the domestic market inverter efficiency. As described above, when the inverter is working part itself also consumes power, so it is greater than the input power to its power output. That is, the efficiency of the inverter inverter output power to input power ratio. If a station 100 watt inverter input DC output of 90 watts of AC power, then it's efficiency is 90%. Currently the world's solar inverters, high efficiency in Europe and America, the European standard is 97.2%, but the price is more expensive, other domestic inverter efficiency is 90% or less, but the price is much cheaper than imports. Outside power, in addition to waveform Select the inverter efficiency is also very important, the higher the inverter to waste less energy efficient solar power inverter‍ electrical power for even more, especially when you use low-power system that more importance obvious.

3000 watt power inverters Power inverter maintenance Precautions

1) UPS should be noted that the use of a well-ventilated environment, DC AC power inverters‍ conducive to heat and keep the environment clean. 

2) Do with inductive loads, such as cash registers, fluorescent lights, air conditioning, etc., to avoid damage. 

3) UPS output load control in about 60% for the best, highest reliability. 

4) UPS load is too light (eg 1000VA, 100VA UPS with load) may cause deep discharge of the battery will reduce the battery life, should be avoided. 

5) appropriate discharge, helps cell activation, such as long-term non-stop electricity, every three months to be artificially broken mains load discharge time with UPS tape, so you can extend the battery life. 

6) For most small UPS, go to work and then open the UPS, to avoid load at boot time to start, should work to close UPS; For network room UPS, because the majority of the high frequency inverter‍ network is 24 hours, so the UPS must run around the clock. 

7) UPS should be charged after discharge to prevent battery damage due to excessive self-discharge.‍
