I have an Eaton 9355 20kva system. Theres an alarm #188 Bypass Failure and notice#105 Bypass Not available. The batteries are also not charging or the battery current is reading 0 amps. When the power goes out the ups fails.

Notice #28 on the Eaton 9130 indicates that the DC link voltage has exceeded the safe operating range. The DC link voltage is the voltage between the positive and negative terminals of the battery bank. It is important to keep the DC link voltage within the safe operating range to prevent damage to the UPS.
The safe operating range for the DC link voltage on the Eaton 9130 is 280-450V. If the DC link voltage exceeds this range, the UPS will show Notice #28 and switch to bypass mode. This means that the UPS will no longer be able to provide power to the connected loads.
There are a few things that can cause the DC link voltage to exceed the safe operating range. One possibility is that the battery bank is not properly charged. Another possibility is that there is a problem with the UPS itself.
If you see Notice #28 on your Eaton 9130, you should first check the battery bank. Make sure that the batteries are properly charged and that there are no loose connections. If the batteries are properly charged and there are no loose connections, then you may need to have the UPS serviced.
Here are some additional tips to help you troubleshoot the issue:

• Check the battery voltage. The battery voltage should be between 28 and 45 volts.
• Check the battery temperature. The battery temperature should be between 10 and 35 degrees Celsius.
• Check the battery connections. Make sure that the battery connections are tight and that there are no corrosion.
• If you have a multimeter, you can measure the DC link voltage directly.

If you have checked all of these things and the DC link voltage is still not within the safe operating range, then you will need to call a qualified technician to diagnose the problem.

the manual covers this, it tells you to read alarm event code
messages they are not in number format but text.
in clear english the alarms.
RTM or call EATON, we are Fixya not EATON,ok>
most error common means bad batteries. 99% are.

Because till u have alarm of configuration error in your system it won't accept the command it will always go into bypass u have to remove configuration error from ups system only then you are able to use ups system in online mode I can help u to fix it don't worry this is my WhatsApp number feel free to contact me Okk +919871039174

it looks like you have a faulty static switch

need to change batteries.
cannot hold charge

Shut down the UPS and replace the batteries.

bypass is not available because your input is going in one phase rotation and the bypass is going another. Both input and bypass needs to be a clockwise rotation. A cheap phase rotation meter will fix this. Call me at Gruber Power Services for free tech. support 800-658-5883 x256 ask for Eric

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:
C A U T I O N
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
illuminated.
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.
