Wave string properties:Off grid pure sine wave inverter

There are two main types, one is sine wave inverter, the other is square wave inverter.

The output of sine wave inverter is the same or better sine wave AC as the grid we use everyday, because there is no electromagnetic pollution in the grid.

The output of square wave inverter is square wave alternating current with poor quality. The maximum value of its positive direction to the maximum value of its negative direction is almost generated at the same time, which has a dramatic unstable impact on the load and the inverter itself. At the same time, its load capacity is poor, only 40-60% of the rated load, without inductive load. If the load is too large, the third harmonic component in the square wave current will increase the capacitive current flowing into the load, and even damage the power filter capacitance of the load.Off grid pure sine wave inverter

In view of the above shortcomings, quasi sine wave (or modified sine wave, modified sine wave, analog sine wave and so on) inverter appears. Its output waveform has a time interval from the positive maximum value to the negative maximum value, and the use effect is improved. However, the quasi sine wave waveform is still composed of broken lines, belonging to the category of square wave, with poor continuity.Off grid pure sine wave inverter

Generally speaking, sine wave inverter provides high-quality alternating current and can drive any kind of load, but its technical requirements and cost are high. Quasi sine wave inverter can meet most of our power demand, high efficiency, low noise, moderate price, so it becomes the mainstream product in the market. The square wave inverter is made of simple multivibrator, whose technology belongs to the level of the 1950s, and will gradually withdraw from the market.

According to the different power supply, the inverter is divided into coal power inverter, solar power inverter, wind power inverter and nuclear power inverter. According to different purposes, it is divided into independent control inverter and grid connected inverter.

In the world, the efficiency of solar inverters is relatively high in Europe and America. The European standard is 97.2%, but the price is relatively expensive. The efficiency of other domestic inverters is below 90%, but the price is much cheaper than that of imported ones.

In addition to power and waveform, the efficiency of inverter selection is also very important. The higher the efficiency is, the less power is wasted on the inverter, and the more power is used for electrical appliances, especially when you use a small power system. [1]

application areaOff grid pure sine wave inverter

1. The 220V power obtained by the inverter on the car is 220V 50Hz, and the high-grade point is sine wave, and the cheap one is generally square wave.

The sine wave is the same as the power used for connecting the socket, but the square wave can also be used. However, if the fan and other equipment with motor are used, there will be some noise. The reason why the square wave is used is that the cost of this modulation method is relatively low. Generally, the power of the on-board inverter is no more than 500 watts, and the air conditioner is generally more than 700 watts. What's more, do you really want to load the household air conditioner??? The air conditioner in the car, including those buses, let the engine directly drive the compressor, not use electricity. If there is another electricity conversion process in the middle, the loss will be greater. And it's not easy to install. It's better to use car air conditioner.

2. It's OK to connect notebook, TV, disc player and other things as long as they are used at their rated power, but it should be noted that they are connected to the battery of the car. Although they are usually 11V, they will automatically protect the power off to avoid too low voltage causing the car to fail to start, but they are not suitable for use when the engine is not running, so if the load is relatively large, they should be built Start the engine. If it's charging the phone, it's OK.

3. On the electric vehicle, there is a module called DC-DC, which is also called DC converter. This module has 48V input and 12V output, so you only need to buy a 12V input vehicle inverter to use. Of course, if you can buy a 48V input inverter, it's better, but it's estimated that it's hard to buy. Moreover, this module can only provide 5A current, but at most 10a, and the lights and other things also need to be used, so it's easy to overload.

Suggestion: if you can, buy an additional DC converter, which is specially used to supply power to your inverter. Then if the DC converter can only provide 5a, the input of the inverter should be less than 5a, otherwise the module may be damaged. Of course, some DC converters have a large current. If there is no place to repair the car, you can go to some electrical stores or call them to repair it Give you a large current, or multiple DC converters in parallel can also be, in short, do not let him overload.

4. There is a VVVF traction inverter on urban rail vehicles, which is used for frequency conversion and voltage transformation. When the train is traction, the high voltage (generally DC750V or DC1500V) is changed into three-phase electricity with adjustable frequency and voltage for the traction electric motor. When the train is braking, the three-phase electric energy generated by the rotation of the traction electric motor driven by the inertia of the train can be converted into direct current and fed back to the grid or eliminated through the energy consumption module Consume.Off grid pure sine wave inverter

The main applications of inverter in communication field are as follows:Off grid pure sine wave inverter

Provide AC auxiliary power for DC power supply.

Some maintenance tools need AC power. DC power cannot provide AC power, which can be provided by inverter.

Provide DC-AC conversion function for photovoltaic grid connected power system.

The direct current generated by the solar energy system is converted into alternating current and input into the Off grid pure sine wave inverter
