APC UPS 8000 inverter fail

[Dieselboy]

After yesterdays power outage the UPS is logging that the inverter has failed. I have done the "braindead" troubleshooting method and during this shutting down method, I smelled a faint electrical burning smell that cleared reasonably quickly.

A new UPS is around 10,000AUD.

I've asked one provider that I am dealing with about replacing the inverter and they advised that they reached out to their APC contact and that they were advised it is not feasible to replace the inverter because it's a high cost and to just buy a new UPS instead.

Anyone been down this road?

I recently replaced the batteries inside around 1.5 to 2 years ago roughly. The APC UPS is Smart-UPS RT 8000 XL

I'm guessing no warranty?

Do you know a good electronics technician, or are friendly with the engineering dept at a local university? The inverter could be removed, repaired and returned to service cheaper/quicker than buying a new inverter/ UPS.

I would guess that the input protection (it would be a mediocre design at best) has failed, along with some of the power handling FET's/IGBTs.

This would be my preferred option but I don't have the necessary skills / knowledge 

APC informed me that there's no way to repair it and they are happy to sell me a new one. Someone is getting a good deal.

Sounds like they're much happier to have you buy new than to send a free or reduced-cost replacement...

Furthermore, they're picking up the faulty unit for free. 🤔
