How to Repair 2000W Sine Inverter
Today, I bought a broken 2000W inverter from a second hand store. I will show you how to fix it.

The repair steps
-Check the fuse
-Check mosfet - Use a multimeter in diode mode. If a value of ~ 500 between pins D and S is a good mosfet, otherwise, replace the mosfet.
-Check the DC filter capacitor 12 - 24V
-Check the 310V filter capacitor
-Check fast diode
-Check PWM signal from SG3525 or TL494 (about 35Khz)
-Check the H-bridge mosfet (310VDC - 220VAC)
-Check the SPWM module and driver ic.

Replace broken components and test with 12 - 24v power supplies at 1A current. If the fault is still, the 1A current cannot damage the inverter.
If you like my video, give me a cup coffee. Thank you very much.
