It's really surprising that my Emerson Liebert GXT MT+ 3000va uses exactly the same board and components as the UPS in your video. Can you help me troubleshoot my unit? Although there is no fault reported, the inverter (output) seems to be damaged, since an incandescent bulb plugged into it will flicker randomly. Can a broken output capacitor also cause such flickering? Thank you

@@ALayoubiMaintenanceCenter That is alright, I understand it takes quite a lot of time to troubleshoot things. I will just try checking the output capacitor based on your video, since my case could just be an early case of fault 14 error.

Inverter On the inverter side all the mosfets is damaged., Sir now I have also installed all the mosfets and the pwm ic (KA7500c) ic that controls them, but now the problem is I am afraid to connect the batteries directly.
