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 (for example, the single-phase load power fluctuation is
greater than 16.67 kVA for a 100 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
more 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, choose
