4.1.4.2 Setting Hibernation Mode

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. The
hibernation function can be set on the WebUI.
● Ensure that the load power is stable. If the system load power fluctuation is
● Check that the number of redundant power modules and racks are appropriate.

greater than the rated capacity of half a module (for example, the single-phase
load power fluctuation is greater than 8.33 kVA for a 50 kVA module), the UPS
may enter and exit from hibernation mode repeatedly.
If the number is insufficient, the UPS may not enter hibernation mode.
On the WebUI, choose Monitoring > UPS System > Running Parameter >
System Settings and set Paral sys hibernate to Enable.
