recovery time.
Capacitor If Capacitor failure detection is
failure set to Enable, the power module
detection
(power unit) performs inverter
capacitor fault detection based on
the settings of Capacitor failure
detection upper limit and
Capacitor failure detection
lower limit. If the power module
determines that the inverter
capacitor is faulty, it shuts down
the inverter to prevent the fault
from expanding.

If this parameter is set to Enable,
the load is light (less than 30%
load), and the load rate of a
certain rack is less than 10%, the
system will generate a bypass
current imbalance alarm and
cannot enter the ECO mode. If
this parameter is set to Disable,
the preceding detection is not
performed. Whether the bypass
current is imbalanced does not
affect the ECO bypass mode.
