Problems solved by technology

[0002] The traditional inverter is directly connected to the main power circuit after the battery is connected. When the battery clip is connected to the battery, a large spark will be generated. If there are flammable objects around the battery, it will easily cause a fire and pose a serious safety hazard. , In addition, the connecting wire is easily damaged when it is often powered on, and the surge current impact is likely to cause accelerated damage to internal components, which also reduces the product life

Description

technical field [0001] The invention relates to an inverter, in particular to an inverter with anti-surge suppression. Background technique [0002] The traditional inverter is directly connected to the main power circuit after the battery is connected. When the battery clip is connected to the battery, a large spark will be generated. If there are flammable objects around the battery, it will easily cause a fire and pose a serious safety hazard. , In addition, the connection line is easily damaged when it is often powered on, and the surge current impact is likely to cause accelerated damage to internal components, which also reduces the product life. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an inverter with anti-surge suppression, no sparks will be generated at the connection when connecting the battery, and the life of the connecting line and the product will be prolonged. [0004] The present inventio...
