inverter charger 12v 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

The DC voltage must be consistent

 Each inverter has a DC voltage value, such as 12V, 24V, etc. 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.

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

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.

Prone to faults in power inverters  

When using the power inverter, if there is a shutdown or alarm, check the following items:

    1) Whether the power of the driven electrical appliance exceeds the rated power value of the inverter.

2) Whether the power inverter is well connected to the battery and electrical appliances.

3) If it is stopped during use, whether it is a temperature alarm, at this time, it can be used continuously after a period of inactivity.
