Vh= 253V
Clr t < 0.20s
3 seconds
Vh:
phase-to-phase (rms) high threshold voltage
setting, the threshold at which the inverter
disconnects itself from the power grid when
abnormally high phase-to-phase AC voltage is
detected.*
Clr t:
clear time.†
Vl= 196V
Clr t < 0.20s
3 seconds
Vl:
phase-to-phase (rms) low threshold voltage
setting, the threshold at which the inverter
disconnects itself from the power grid when
abnormally low phase-to-phase AC voltage is
detected.
Clr t:
clear time.
Vph=
0V
Clr t < 0.20s
3 seconds
Vph:
phase-to-neutral (rms) high threshold
voltage setting.
Note
: Phase-to-neutral threshold
voltages are disabled for European GT Inverter
models. This screen always displays “0V”.
Clr t:
clear time.
Vpl=
0V
Clr t < 0.20s
3 seconds
Vpl:
phase-to-neutral (rms) low threshold voltage
setting.
Note
: Phase-to-neutral threshold voltages
are disabled for European GT Inverter models.
This screen always displays “0V”.
Clr t:
clear time.
Fh= 51.0Hz
Clr t < 0.15s
3 seconds
Fh:
frequency high threshold setting, the threshold
at which the inverter disconnects itself from the
power grid when abnormally high frequency is
detected.
Clr t:
clear time.
Fl= 48.0Hz
Clr t < 3.10s
3 seconds
Fl:
frequency low threshold setting, the threshold
at which the inverter disconnects itself from the
power grid when abnormally low frequency is
detected.
Clr t:
clear time.
Reconnect Delay
185.00s
3 seconds Setting for the reconnect delay for the protection
timer. After a fault clears for the specified clear
time, the protection timer starts counting down
before the inverter attempts to deliver power to the
grid.
* The voltage and frequency thresholds, clear times and reconnect delay in
Table 5-1 can be adjusted for multi-unit installations producing 30 kW or more
(with the permission of the local utility) using GTConfigLite software.
