1. The DC voltage should be consistent

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 to the DC voltage connected to the inverter, and marked with positive and negative poles. Red represents the positive pole (+), black represents the negative pole (1), and the battery is also marked with positive and negative poles. Red represents the positive pole (+), and black represents the negative pole (2). 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 objects in Zhouguo. It should be kept away from flammable and explosive materials, and should not be placed or covered with other items on the machine. The operating environment temperature should not exceed 40C

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

 6. The interval between two power ups 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 rabbit accidents, users are strictly prohibited from opening the chassis for operation and use

 10. When suspecting a malfunction of the machine, please do not continue to operate or use it

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