An inverter is an electronic device used to convert direct current (usually 12V DC) into alternating current (AC) with an output power of up to 2000 watts or 20 watts. It is widely used in scenarios where a low-voltage DC power source (such as a car battery or solar cell) needs to be converted to a high-voltage AC power source to power various electrical devices.
The working principle of 2000 watt inverter is similar to that of ordinary inverter, which mainly includes the following steps:
- DC input: receives 12V DC power.
- Booster circuit: converts 12V DC to a higher DC voltage.
- Inverter circuit: converts the high voltage DC to AC.
- Output filtering: outputs smooth AC power through the filter.
Power Output
2000 Watt inverter, suitable for driving high power appliances and equipment, such as refrigerators, air conditioners, power tools, and so on. Can supply power to household appliances and electronic devices that require higher power.
20 watt inverter, suitable for driving low power devices such as cell phone chargers, small LED lights, etc. Can only power electronic devices and small appliances that require low power.
Application Scenarios of 2000 Watt Inverter
- Vehicle-mounted devices: powering high-power devices in the car, such as microwave ovens, TVs, etc.
- Outdoor activities: to provide power for various high-power electrical appliances during camping or field operations.
- Emergency Backup Power: Provide temporary power for household appliances during power outages.
- Solar System: Used in solar power generation system to convert high power DC power.
Application Scenarios of 20 Watt Inverter
- Small electronic devices: charging small electronic devices such as cell phones and tablet PCs.
- Portable lighting: to drive small LED lights, USB fans and other low-power devices.
- Low-power applications: for application scenarios that require only a small amount of power, such as small sensors or electronic experimental equipment.
Design and Function
A 2000 watt inverter requires a powerful inverter circuit and heat dissipation system, is usually large and heavy, and can output a pure sine wave, corrected sine wave, or square wave as needed. It also has a variety of protection functions such as overload protection, short-circuit protection and overheating protection.
The 20 watt inverter is simple in design, small in size, light in weight and easy to carry. Usually can only output simple modified sine wave or square wave.
Cost and Efficiency
Due to the high power output and complex design, 2000 watt inverters are relatively costly. Losses are also relatively high in high power operation.
Due to the low power output and simple design, 20 watt inverters are less expensive and have relatively low overall losses.
To summarize
The main differences between 2000 Watt inverters and 20 Watt inverters are power output, applicable scenarios, and design complexity. 2000 Watt inverters are suitable for applications that require high power output, such as large household appliances and tools, while 20 Watt inverters are suitable for low-power devices, such as cell phone charging and portable lighting. Choosing the right inverter needs to be based on specific power requirements and application scenarios.
