Hello, I have a EATON EX RT 11 that shows ;MODULO DESCONEC. - 1CKI46013 V00D' error on screen. What causes this error? Help me please!

call the ups engineers for an answer to the problem when connected to solar power
there may be a problem in that solar panels produce various voltages during the day ( depending on the cloud coverage ) and the ups requires a reasonably steady input voltage to operate properly
I have found the eaton ups product to reliable so the suggestion to talk with the engineers to ensure that the system is compatible with the solar set up would be to your advantage

There`s two configurations that you need to check.
On UPS display, what voltaje is showing as output voltage?
There`s a chance that it is configured to 200 vac, then the transformer module will convert this to 100/200 vac.
If this is not the situation, probably the error is in the input connection of transformer module.

Replace your batteries

Take all steps to bypass the UPS according to the manual.
Turn the UPS.
Loosen the front plate.
The fans sitting screwed onto another plate which can be unscrewed.

than press on to start the inverter

Cyrus, Eaton will never be the same again. The fault led suggests a permanent disconnect with the articulation franchise of the ovulation event monitor. Reset will not help.

This could be because of bad batteries or you need to adjust the float voltage. First replace batteries

Matias,
Try using the Intelligent Power Software Suite (IPSS):

If you are trying to monitor the UPS, use Intelligent Power Manager (IPM). If you are trying to shutdown the Virtual Machine safely, use Intelligent Power Protector (IPP).
