5.10 Setting Hibernation Mode
Prerequisites
Ensure that the load power is stable. If the system load power fluctuation is greater than
the rated capacity of half a module, the UPS may enter and exit from hibernation mode
repeatedly.
Check whether the number of UPS redundant modules and the number of racks are
appropriate. If the number is insufficient, the UPS may not enter hibernation mode.
Context
When the load power is small and stable, you can shut down the inverters in some power
modules so that these power modules enter hibernation mode and other power modules bear
all the load power. This improves the system efficiency in the case of small load power and
increases the power module service life.
