5.12 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 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. 
 
Check that the number of redundant power modules and racks are appropriate. If the 
number is insufficient, the UPS may not enter hibernation mode.

1.  On the WebUI, choose Monitoring > UPS system > Running Parameter and set Paral 
sys hibernate to Enable. 
2.  Set the module cycle hibernation period to an integer ranging from 1 to 100. The default 
value is 30.
