Inverter is no output voltage after the customer has used it for a period of time
Model
BP Series Pure Sine Wave Inverter 36VDC 220VAC 1000W
Description
There is no output voltage after the customer has used it for a period of time.
Analysis of the possibility of the cause
1. The disassembly test found that there is no auxiliary 12V voltage. After testing, it is determined that there is no auxiliary voltage due to the failure of the step-down board.
2. Test the step-down board, and found that one of the diodes is damaged. It is roughly judged that the DC input is too large when it passes through the step-down board and the diode is damaged.
Solutions and steps
Replace with another diode that is more impact resistant.
