Single/Parallel, Output voltage level and Output frequency, as well as Battery capacity
and Number of cells must be the same as the actual values. Otherwise, an alarm may be
generated, or other serious faults may occur.
Set basic system and battery parameters, as shown in Figure 4-34.
Figure 4-34 Basic Param. screen
Output voltage level
The value for the system output voltage level can be set as 380 V, 400 V (default), or 415 V.
After the parameter value is changed, the upper thresholds for the bypass voltage are restored
to the default values. The parameter is configurable after the inverter shuts down.
If Output voltage level is 380 V or 400 V, the default upper threshold is 15% and the default lower
threshold is 20%. If Output voltage level is 415 V, the default upper threshold is 10% and the default
lower threshold is 20%. The parameter is configurable after the inverter shuts down.
The value for the UPS running mode can be Single (default) or Parallel.
The value for the system output frequency can be 50 Hz (default) or 60 Hz.
The value range for the battery string capacity is 5 Ah to 9999 Ah. 300 Ah is
set by default for the 200 kVA UPS, and 350 Ah is set by default for the 300
kVA UPS.
Each 12 V battery consists of six cells. The value range is 180 to 276. The
default value is 240.
