The internal circuit board rusts of BP Series 12VDC 220VAC 600W inverter

Model

BP series pure sine wave inverter  600W 12VDC 220VAC

Description

Cannot start the inverter up. Part components of the internal circuit board rusts.

Analysis of the possibility of the cause

Water has got into the inverter or it was used in extremely humid surroundings. Both front-end and back-end MOS tubes have been damaged.

Solutions and steps:

Deliver it back to factory to take a complete inspection.
