I was given this inverter for free, that if I can repair I can use as a backup power.
"Pure sine wave Inverter 3000W"
"Power that really moves"
"DC-AC"
text on the top of the case.
When i first opened it I did notice a burned YMP230N55.
I found on aliexpress that they offer YMP230N55 as a replacement for the more expensive IRF2804.
I bought 5x IRF2804, replaced 3x of them, the burned one, and one next to it, and the one closest to the right end of the board. I have 2 more IRF2804 to test with.
I turned on the board with the replaced FETs and we heard a sound that the inverter powered up actually for a second.
The same mosfet that was burned, smoked out immediately.
What can be causing this ? Any ideas by looking at the pictures ?
Thank you in advance
