5.12 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 (for example, the single-phase load power fluctuation is
greater than 9.17 kVA for a 55 kVA module), the UPS may enter and exit from hibernation
mode repeatedly.
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. The hibernation function can be set on the WebUI.
Procedure
Step 1
On the WebUI of the system, choose
Monitoring
>
Param. Settings
>
System Settings
and
set
Paral. sys. hibernate
to
Enable
.
Step 2
Set the module cycle hibernation period to an integer ranging from 1 to 100. The default value
is 30.
