5.2.3.2 Setting Hibernation Mode

Prerequisites
Before enabling 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 more load power. This improves the system efficiency in the
case of small load power and increases the power module service life.
Procedure
Step 1 Choose System Info., tap

Ensure that the load power is stable. If the system load power fluctuation is
greater than the rated capacity of half a module (for example, the single-
phase load power fluctuation is greater than 5 kVA for a 30 kVA 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.
