power inverter 12v to 220v 2000w

The working principle of the power inverter?

The PWM pulse is realized by the CPU microprocessor, and the low voltage 12V is changed to a DC voltage of about 300V through a high-frequency transformer. 

Then the CPU outputs a 50 Hz AC drive signal to drive the power switch to work. 

Through the successive conduction and conversion of the power tube, an AC voltage with an average effective value of 220V in the form of a square wave is output.

Precautions for using inverter

　1. The DC voltage must be consistent

 Each inverter has a DC voltage value, such as 12V, 24V, etc. #low frequency inverter           It is required that the battery voltage must be the same as the DC input voltage of the inverter. For example, a 12V inverter must choose a 12V battery.

　2. The output power of the inverter must be greater than the power used by the electrical appliances, #off grid solar inverter         especially for electrical appliances with high power when starting, such as refrigerators and air conditioners, with a larger margin.

　3. The positive and negative poles must be connected correctly

The DC voltage connected to the inverter is marked with positive and negative poles. 

Red is positive (+), black is negative (-), the battery is also marked with positive and negative, red is positive (+), black is negative (-), and must be connected to positive (red to red), negative Connect negative (black connect black). 

The diameter of the connecting wire must be thick enough, and the length of the connecting wire must be reduced as much as possible.

  4. It should be placed in a ventilated and dry place, beware of rain, #inverter 24v 220v 5000w          and be at a distance of more than 20cm from surrounding objects, away from flammable and explosive materials, and do not place or cover other objects on the machine. The use environment temperature is not more than 40℃ .

  5, charging and inverter cannot be performed at the same time. That is, do not insert the charging plug into the electrical circuit of the inverter output during inverter.

　6. The interval between two startups is not less than 5 seconds (cut off the input power).

　7. Please wipe with a dry cloth or anti-static cloth to keep the machine tidy.

　8. Before connecting the input and output of the machine, please ground the casing of the machine correctly.

　9. To avoid accidents, it is strictly forbidden for users to open the case for operation and use.

　10. When you suspect that the machine is malfunctioning, please do not continue to operate and use it. The input and output should be cut off in time, and the qualified maintenance personnel or the company's special maintenance unit will check and repair.

  11. When connecting the battery, please make sure that there are no other metal objects on your hands to avoid short circuit of the battery and burn the human body.
