The inverter is a commonly used device and is available in general electronics markets. However, since the power of 5000w is relatively large, you generally only need to book it in advance or buy it online.
Inverters can be divided into several types: square wave inverter (modified sine wave inverter), pure sine wave inverter, power frequency inverter, and solar inverter. Inverter
The square wave inverters currently sold on the market are basically improved square waves, called modified sine wave inverters, and the price is around 0.3 yuan/W. Due to their low price, It has a wide range of applications, and most people buy this type of inverter, which is mainly suitable for household and outdoor emergency power use.
The price of a pure sine wave inverter is around 0.5-1 yuan/W. Since the output waveform of a pure sine wave inverter is the same as that of the mains, basically as long as the power of the loaded equipment does not exceed the inverter The output power can be driven. Mainly suitable for carrying inductive loads, such as power tools, motors, etc.
The price of power frequency inverter is about 0.7-1 yuan/W. The power frequency inverter power supply first inverts the DC power into power frequency low-voltage AC power; then boosts it to 220V, 50Hz through the power frequency transformer. AC power is supplied to the load. Its advantage is that the structure is simple and various protection functions can be realized at lower voltages. Because there is a power frequency transformer between the inverter power supply and the load, the inverter power supply operates stably and reliably, has strong overload capability and impact resistance, and can suppress high-order harmonic components in the waveform. However, power frequency transformers are also bulky and expensive, and their efficiency is relatively low. Tool frequency converters generally provide output voltage, frequency adjustment and other functions, and are mainly suitable for high-end applications, such as medical equipment and enterprise-level applications.
Solar inverters are the core equipment of photovoltaic power generation, with power ranging from tens of watts to hundreds of kilowatts. The price of solar inverters varies greatly depending on their functions.
Taking the online sales price of BELTTT's 5000W inverter as an example, its modified sine wave inverter is about 1,500 yuan, pure sine wave inverter is about 2,500 yuan, and power frequency inverter is about 1,500 yuan. The price of an all-in-one solar off-grid power generation and inverter machine is about 3,500 yuan, about 4,500 yuan.
The prices of different brands may be different. If it is a no-name or non-full-power inverter, for example, one with a false power rating, the price will be much cheaper. No matter what brand you buy, it is best to Find out how much power it actually has.
