Working principle of inverter

Instructions for use:

1. The DC voltage should be consistent: Each inverter has connected DC voltage values, such as 12V, 24V, etc. It is required to choose a battery voltage that must be consistent with 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 usage power of the electrical appliances, especially for appliances with high power during startup, such as refrigerators and air conditioners, a larger margin should be left;

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 represents the positive pole (), black represents the negative pole (-), and the battery is also marked with positive and negative poles. Red represents the positive pole (), and black represents the negative pole (-). When connecting, it must be positive (red to red) and negative (black to black). The diameter of the connecting wire must be thick enough and the length of the connecting wire should be minimized as much as possible;

4. It should be placed in a ventilated and dry place, careful of rain, and at a distance of more than 20cm from surrounding objects, away from flammable and explosive materials. It is strictly prohibited to place or cover other items on the machine, and the operating environment temperature should not exceed 40 ℃;

5. Charging and inverter cannot be carried out simultaneously. Do not insert the charging plug into the electrical circuit of the inverter output during inversion;

6. The interval between two starts should not be less than 5 seconds (cut off the input power);

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

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

9. To avoid accidents, it is strictly prohibited for users to open the chassis for operation and use;

10. When there is a suspicion of a malfunction in the machine, please do not continue operating and using it. Input and output should be cut off in a timely manner, and qualified maintenance personnel or maintenance units should inspect and repair it;

11. When connecting the battery, make sure there are no other metal objects on your hands to avoid short circuits and burns to the human body;

12. Based on safety and performance considerations, the installation environment should meet the following conditions:

1) Dry: Do not immerse in water or rain;

2) Shady and cool: temperature between 0 ℃ and 40 ℃;

3) Ventilation: Maintain no foreign objects within 5cm of the shell, and ensure good ventilation of other end faces.
