Description
Specifies the system output
voltage level. This parameter
is configurable only after the
inverter shuts down. After
you change the voltage level,
the upper limit of the bypass
voltage restores 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 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 Output freq.
track rate (Hz/s) is slow, the
inverter frequency is different
from the bypass frequency
when the bypass frequency
changes. If 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
Output freq. track rate
(Hz/s) is fast, the inverter
frequency is unstable.
