Simple analysis about the use of power inverter voltage negative impact analysis:

1, the voltage use is more important, relatively speaking, the use of the power inverter is better than the other Pure sine wave power inverter to stabilize a bit, but the voltage is relatively better than other power products to high. If the voltage careless use or imprudent selection voltage product would result in the product caused by improper use of the negative effects - short-circuited.
2, the negative influence of the voltage used can cause changes in the product nature. Simple to understand because of exposure to high voltage, temperature, and stability of the product can not be directly used to meet the original product, the voltage is too high lead to problems with the original product.
3, not only the voltage, current, power products stability is also very important to the stability of the current use of more unreliable unsafe, in addition to the choice of product to choose high product stability, for the protection of the product itself is very Important ah!
On the analysis of this point can be understood that such a clear understanding of the choice to buy or use the product when it simpler to choose their own power inverter voltage power products using negative impact. Use the time to know the use of power products should pay attention to what the problem then later choose to use will be more convenient and reliable the more at ease! !

Power inverter voltage using the negative impact analysis

 Under normal circumstances no matter what the product is there are certain advantages also have some negative impact, whether under normal circumstances are accounted for most of the advantages. And the use of power is the need to carefully select the products more safer product use more reliable! Understanding the power of the 5000w inverter charger voltage can understand the negative effects of the product advantages and disadvantages. In this case, when selecting power product is, you can learn about the negative impact of product choices so you can choose to select power products easier to use a more suitable product. Not just the battery power inverter needs so choose, there are a lot of use of an inverter, UPS power supply cabinet and power supply products, etc. These are the same principles.

Greater use UPS inverter output AC stability

 Life around are impressive to see power products, and the development of the most ambitious is the quickest and most efficient use of the inverter, because times change, people's living standard has been some improvement, but more to the wider power exchanges on more The need stability in order to meet consumer demand! For inverters people are more desirable because "UPS inverter output AC power using a higher stability."
Because the use of power products is relatively stable to have a certain use would be more secure, more assured consumers will use these power products. True, the use of alternating current power products is also very important.
Many people understand the question: inverter type is not a lot? Is AC for each type of product is the same?
Well, not exactly, 500w solar inverter type is relatively more like power sine wave inverter, sine wave inverter, power inverters, inverters, UPS and power supply cabinets can be said of these power products It is part of the inverter type, but also can say belong to the inverter type.
Because these are power products, but relatively speaking, using the power of nature, functions, voltage, power, performance, current, power products, etc. These are not the same, the most important is that these AC UPS inverter output is not same.
Relatively higher stability UPS inverter output AC power use under normal circumstances, and the 4000w solar inverter using it even better and more reliable. For the inverter output current and alternating current are basically the same type of, but not the same magnitude of the efficiency and results of use are not the same, the stability of the power supply is a prerequisite for safe use!

Shortcomings and deficiencies still exist in power inverters

Although the development of the modern era of power products has been some development change, but is better than gold, even the development of each product, then it has also have some disadvantages. For 5000w charge inverter versa. Analysis of the shortcomings and deficiencies still exist in power inverters for use is a certain degree of help.
Analysis of the shortcomings and deficiencies still exist in the power inverter as follows:
1, smaller capacity, can not meet the demands of modernization. While only one main one, after a fault, if fault has caused another disruption of network threats. Also switching time is longer, in a widely used computer information age, one can not meet.
2. Independent Union of the Off grid inverters can not easily achieve system expansion. Two main and backup, large-scale systems are subject to a distribution panel, life is short.
3, easily disturbed and malfunction. While its own electromagnetic compatibility is poor, interference from other hosts from both radiation and conduction, resulting in a great threat. In addition bulky, large noise, heat badly.
4, individual inverter body system is intelligent enough to perfect, phased and bulky, field area, heavy weight, high component costs, high maintenance costs, high failure the inverter, short life.
5, the output waveform is poor, a high harmonic content. The output is typically a square wave or modified sine wave, for demanding network is inappropriate, likely to cause network errors.
Relatively speaking, these are some of the old-fashioned power inverters have some shortcomings and deficiencies, but now use inverter - Power Inverter has been some reform, more perfect. But for (Independent Union inverters can not easily achieve system expansion. Two main, backup, large-scale systems are subject to a distribution panel, life is short) that there is still a lack of need to better.

Inverter Current research and development at home and abroad

Inverter, rectifier means flyback converter, its role is by opening a semiconductor power switching devices on and off action, the DC can be converted into an AC power of power electronic converters. Inverter applications will become increasingly important. The 21st century is energy development, resource utilization and environmental protection co-ordination century of development, optimize the use of energy and the development of clean energy is an important part of the energy resources and environmental strategies for sustainable development.
Oil, gas and coal and other fossil fuels, known as the world's three major energy will gradually be depleted, hydrogen and renewable energy will gradually replace fossil fuels and become the subject of energy for human use, the changes will force this energy generates electricity generation high efficiency and low fuel cell power generation a big change, the use of hydrogen and renewable energy, will become the main power generation. Therefore, the 5000w pure sine wave inverter technology in the field of development and utilization of new energy has a crucial position.
SPWM (Sinusoida-PWM) sinusoidal pulse width modulation sine wave modulation, the carrier is a triangular wave or a sawtooth pulse width modulation method, which is 1964 by A.Schonung and H. Stemmler the communication system modulation technique applied to the inverter generated, because of the slow speed of the switching device without timely promotion, until then equal to the Bristol University SRBowers 1975 SPWM technology only then formally applied to the inverter technology the performance of the inverter is greatly improved, and has been widely used and development, but also to sine wave inverter technology has reached a new height. Features of this technology is simple in principle, versatility, control and regulation performance, with the elimination of harmonics, regulate and stabilize the output voltage of a variety of roles, it is a good waveform Improvement Act. Since then, a variety of PWM techniques have emerged, such as third harmonic injection PWM, space vector modulation, current hysteresis PWM, etc., become the high-speed switching devices of the inverter dominant control. So far, the development of a 48v to 220v power inverter technology has been basically perfect.
In the sine wave inverter control method, at home and abroad there are more studies than PID control, deadbeat control, bicyclic feedback control, repetitive control, variable structure control, fuzzy control and neural network control. PID control is a conventional control method, because of its simple algorithm mature design process overly dependent on system parameters, robustness and high reliability, in simulated sine wave inverter control system has been widely used. With the development of microprocessor technology, with faster static and dynamic response characteristics of the digital PID algorithm also has been used.

Solar inverter maximum power point tracking control principle

Maximum power point tracking (maximum power point tracking,) control is the real-time detection of the Solar power inverters cell voltage and current output characteristics, the use of certain control strategies to detect the current operating conditions of the solar cell maximum possible power output by changing the impedance of the current situation The maximum power output to meet the requirements. Thus, even in poor lighting, solar output power is reduced or inadequate, the system can still run best under the current conditions.
Take advantage of the energy generated by photovoltaic cells is a basic requirement of photovoltaic power generation system to solve this problem can be added maximum power point tracking device between the photovoltaic cell and the load, so that the photovoltaic cell maximum output power has always been able to make more efficient use of solar energy.

Transformerless inverter use advantages of BIPV

Conventional inverter BIPV often limit the use of the photovoltaic inverter system design, for example, 1 MW system, using two 500KW inverter system need to install the inverter on the ground, for this reason traditional inverters relatively large size and weight, is not suitable for installation in roofs. If transformerless inverters, its small size and because of its light weight, can be directly connected with the solar panels on the roof.
A plurality of inverters may be connected in parallel without the use of a transformer, and power can be used directly, in order to achieve stable performance. Transformerless 300w solar inverter technology uses a much larger power optimizer (Line Reactor) and smaller triangles filter capacitor. These smaller triangles by means of a filter capacitor series resistors are buffered, and thus improve the stability of the control system, and to reduce the interaction between the parallel 3000w solar inverter . A design with a single engine 500 kilowatts inverter also reduces the number of parts, thereby improving overall system reliability.
Using multiple inverters do conventional photovoltaic systems, each must have a separate isolation transformer to match, resulting in reduced efficiency because there is energy loss isolation transformer. Without transformer type no isolation transformer, thus obtaining additional power from photovoltaic modules to supply energy to the load.
Without a transformer, DC AC power inverters smaller size, lighter weight for the power integrators to provide greater freedom in installation and overall system design. Because of weight restrictions and the need of reinforcement measures, five-storey building in the roof of the building to install a conventional inverter from a cost point might be prohibitive, but the designer was able to make a transformerless inverter is installed in commercial buildings on the roof (not installed in the basement), so that it is directly connected with the fifth floor of the mounting plate. This design not only can remove up to five floors of expensive DC wiring, but also shorten the length of the AC cord and reduce associated costs.

watt power inverter Car cigarette lighter socket can output more power for electricity ?

To take power from the cigarette lighter socket , the inverter should be able to drive the power of a hundred -watt electrical appliances . But customers reflect , then P4 laptop solar inverters‍ minutes later, the inverter automatically power off and alarm. We know , P4 laptop power of about 90 watts, is higher . As some of the models in this circuit from the battery to the socket cigarette lighter on the use of non-compliance leads and cigarette lighter socket , large losses in the current surge in the circuit , the supply voltage of the inverter to a sharp decline undervoltage protection circuit action is the critical point - 10 volts , causing the inverter to stop power supply . To solve this problem , and to ensure that in future the normal , safe and reliable use of the inverter , it is recommended to wire the circuit is converted into high-quality copper wire cross-sectional area of ??2.5 mm2 or more , and if necessary replace the cigarette together socket.

Another point to note is taken from a car cigarette lighter socket DC power to the inverter , car cigarette lighter only supports 300W power, or car cigarette lighter power inverter due to 500w power inverter‍ the use of excessive and burn , if you must to use more than 300W inverter , it can give an inverter directly from the car battery wiring.

1500 watt power inverter What is the risk of using an inverter

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

1500 watt power inverter How is the battery is equipped with a suitable inverter?

If the specifications of the battery is 12 V, 50 Ah, we solar power inverter‍ 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 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 ehicle power inverters‍ users, it is best to use an inverter in not more than 85% of the rated power of the state.
