Description
Specifies the system output
voltage level. This parameter
can be set only after the
inverter shuts down. After
you change the voltage level,
the upper limit of the bypass
voltage is restored to the
default value. (If the voltage
level is 380 V or 400 V, the
default upper limit is +15%.
If the voltage level is 415 V,
the default upper limit is
+10%.)
The output voltage can be
slightly adjusted based on
the onsite power distribution
condition to ensure a
minimum difference between
the output voltage and the
bypass voltage and to
facilitate uninterruptible
power supply when the UPS
transfers from normal mode
to bypass mode.
Specifies the system output
frequency level.
This parameter can be
adjusted based on site
requirements. If the output
frequency track rate is slow,
the inverter frequency is
different from the bypass
frequency when the bypass
frequency changes. If the
output is overloaded or the
inverter is faulty, an
interruption (less than 20
ms) occurs when the UPS
transfers from normal mode
to bypass mode. If the output
frequency track rate is fast,
the inverter frequency may
be unstable.
