A Eaton 9315 ups 80kVA has Inverter failure and AC Output Over voltage. Any help?

Sound like IGBT. It's a black block looking device mounted directly on the heat sink of the inverter leg. Remember you have 3 legs total to check. If I remember right there are 3 IGBT's per leg. You could also have blown a DC capacitor.

I Have an 80KVA APC Symmetra PX and one of the power module is not working I already change position with other power module and still not working


Please clarify. If you change the suspected module position and the module is not working, then the problem is with the module. If you replaced a working module in the non working module position and it does not work then there is a problem with this particular slot. Normally you would replace the faulty module with a working one in its slot and things would be clearer. I do not understand well the way you describe the problem, however each module has a micro-switch on the side which activate the start up of the module. have a look at it. i hope this will help

APC UPS 500 and 600, both say (PowerChute) commercial power is off and running on battery when the commercial power is fine. They end up shutting down my systems. After a while they run normal.

This is usually caused by a popped circuit breaker on the UPS. From the UPS Manual:

Disconnect non-essential equipment from the
Back-UPS. Reset the circuit breaker (located
on the rear panel of the Back-UPS) by pushing
the circuit breaker button fully inward
until it catches.

You can find the user manual here:

"On Battery" Alarm Sounds when Power Available.

if this comes sometimes and goes, this means that the power to ups is sometimes deviating from the specific ups input range, hence the ups is rejecting it. mesure the input voltagesand frequency with a multimeter and check whether they match the specified ones in the ups manual. aslo with some ups there are switches that you use to set the input voltages or number of phases in the ups input. check the manual to see whetther your ups has such.

How to take ups in manual bypass mode.

You definitely want to follow the manual procedure to avoid a possible load loss:

9.1.4 Transfer from Normal to Bypass Mode
To transfer the critical load to Bypass mode:
In Bypass mode, the critical load is not protected from commercial power interruptions and abnormalities.
1. Press the CONTROLS pushbutton on the main menu bar. The System Controls
screen appears.
2. Press the BYPASS pushbutton on the System Controls menu bar.
The UPS transfers to Bypass mode and the critical load is immediately supplied
by the bypass source. If the bypass source is not available, the power processor
remains on and an alarm sounds.
3. The UPS is now operating in Bypass mode and the BYPASS status indicator is
The power module (PM) status indicates READY. The system is now on bypass
and the UPS power processor remains on.

At this point, you can operate an external bypass switch to get to maintenance bypass if needed.
