The 2000W inverter output short circuit no response to power on

Model

BP series pure sine wave inverter 2000W 12VDC 220VAC


Description

The customer describes the output short circuit, the inverter has no response when it is turned on, and there is no output voltage.

Analysis of the possibility of the cause
1. Check the internal components, 10 of the 12 front MOSfets are damaged, 2 of the rear MOSfets are damaged, and the rear driver board is damaged.
2. Because there is no specific on-site situation, it is impossible to confirm the specific cause of the failure. After replacing all damaged components, the inverter runs normally.
