The value range of Capacitor failure detection upper limit is 10–13 A and the default
value is 13 A. When the inverter capacitor current exceeds the current specified by this
parameter, the power unit determines that the inverter capacitor is faulty and shuts down
the inverter.
Capacitor failure detection lower limit (A)
The value range of Capacitor failure detection lower limit is 0–2.5 A and the default
value is 2.5 A. When the inverter capacitor current is lower than the current specified by
this parameter, the power unit determines that the inverter capacitor is faulty and shuts
down the inverter. If Capacitor failure detection lower limit is set to 0 A, the power
unit does not perform inverter capacitor fault detection.
Input cur. limiting
Enable or disable input current limiting for the UPS to protect the D.G.
Input cur. limiting ratio (%)
Limit the input current to protect the D.G. The value can be 50%–200%, 200% by
default.
No-load output shows zero
If this parameter is set to Enable, the output current and load ratio will be displayed as 0
in the case of zero load. If this parameter is set to Disable, the output current and load
ratio will not be displayed as 0 in the case of zero load.
It is recommended that you retain the default input parameter settings.
D.G. mode
Enable or disable D.G. mode. Set this parameter when a D.G connects to the input PDC.
Select Enable when a D.G. is detected over dry contacts.
D.G. power limiting (kVA) and D.G. charger power ratio (%)
Set these two parameters to control the valid input current and limiting input current,
preventing load impact and facilitating cooperation between the UPS and the D.G. The
D.G. power limiting (kVA) setting range is 0–5000 kVA. The default value is 800 kVA
