Many people want to use the inverter, don't know how to choose inverter, inverter manufacturers today classified some detailed analysis: inverter waveform is mainly divided into two classes, one kind is sine wave inverter, another kind is fixed wave inverter. Sine wave inverter, adopts PWM pulse width modulation method to generate correct wave output, around 20% due to the existence of harmonic distortion, not with air conditioning and other perceptual load, but can take light impedance load, etc. Sine wave inverter adopts the isolation coupling circuit, device is simple, high efficiency. Pure sine wave inverter adopts the isolation coupling circuit design, circuit is relatively complex, high cost, can be connected to any common electrical equipment ( Including TV, LCD monitor, etc. , especially refrigerators perceptual load) Without interference. Inverter in isolation are divided into high frequency machine and machine, power frequency inverter followed the work of a 50 hz frequency isolation transformer, power frequency inverter; Use of high frequency switch technology, with high frequency switching element or high frequency isolation transformer instead of power frequency transformer in inverter, high frequency inverter. Inverter power frequency is stable and reliable power components, load capacity and impact resistant ability, defect is low efficiency, heavy weight, the price is higher. High frequency inverter with high frequency isolation and not isolation, advantages of small volume, high efficiency, low price, defect is slightly low impact resistant ability. If the load is inductive load, such as impact is larger motor but often do not move, advised to choose a power frequency inverter, if the load is smaller resistance to impact load, often move, advised to choose a high frequency inverter. Characteristics according to the impedance load classification can be divided into: resistive load and inductive load, the capacitive load. Resistive load: current and voltage no phase difference of load impedance load, such as, light bulbs, electric furnace, electric rice cooker. Inductive load: a phase difference when the load current hysteresis voltage for the inductive load, such as washing machines, air conditioners, refrigerators, water pump, smoke lampblack machine with motor load and the transformer, relays, such as compressor, etc. Capacitive load: current advance a phase difference of the negative voltage load for capacitive load, such as compensation capacitor use switching power supply, computer, TV and so on at home. Motor start and other perceptual load power is the power rating of 5 - 7 times, when calculating the inverter power, to take the load starting power into consideration. , such as if the load is the elevator cannot directly and the inverter output at the connection, because when the elevator down, motor reversal, will produce a counter electromotive force, into the inverter, the inverter was damaged. If you must use off-grid system, it is suggested that between the inverter and the elevator motor with a frequency converter. If pv systems used for pumping water only, and can build a water tower, recommend the use of photovoltaic pumping inverter, can save the cost, such as a pump 2 p, if the normal inverter, are more than 5 kw off-grid inverter to drive, but also with more than 200 ah battery, the total cost of more than 10000 yuan, but if use pumping frequency inverter, need only 2 kw, the price is less than 5000 yuan. The output power of the inverter should be greater than the power of the load. For monitoring station, station demanding situations, such as power output is the sum of all of the load power. But for poor families generally, taking into account all load may not open at the same time, in order to save cost, can be in the sum of the load power multiplied by zero. 7 - 0. The coefficient of 9.
With technology speeding up in lighting speed, have created quite a name for itself amidst charge controller manufacturers and it happens to have a lot of benefits as well.
The 21st century is sure to bring more innovation, new services and newer technology, thus new products and services to sell. Wenzhou Xihe Electric Co.,LTD. will continue to shape and lead the markets in which it chooses to compete.
Wenzhou Xihe Electric Co.,LTD. harnesses science and technology to create products that support safer and healthier living and that enhance the overall quality of life.
custom inverter are raising the stakes of social marketing, but they also ease the sales process by providing ways for charge controller manufacturers to effectively interact with customers.
