Minimum Grid
Voltage
Displays as:
Min AC Volts%:
This parameter sets the trigger
point value for “AC voltage low”
(0012) fault. If the grid voltage is
below this parameter’s value, the
fault is triggered. The lower limit
of this parameter is restricted by
UL requirements. 33 Percentage
of
Nominal
voltage 88 95 88
Maximum Grid
Frequency
Displays as:
Max AC Freq:
This parameter sets the trigger
point value for “AC frequency
high” (0011) fault. If the grid
frequency is over this parameter’s
value, the fault is triggered. The
upper limit of this parameter is
restricted by UL requirements. 34 Hertz 60.5 60.5 59.5
Minimum Grid
Frequency
Displays as:
Min AC Freq:
This parameter sets the trigger
point value for “AC frequency
low” (0010) fault. If the grid
frequency is below this
parameter’s value, the fault is
triggered. The lower limit of this
parameter is restricted by UL
requirements. 35 Hertz 59.5 59.5 60.5
Maximum Ground
Fault Current
Displays as:
Max Gnd Flt I
This parameter sets the trigger
point value for “Ground Over
Current” (0033) fault. Once the
current through the ground cable
is greater than the value of this
parameter, the fault is triggered. 36 Amps 10 20 1
Peak Power Tracker
Reference Voltage
Displays as:
PPT V Ref:
This is the initial PV voltage the
inverter is going to try to keep as it
goes into on line mode. If the
power tracker is off, the inverter
will draw current from the PV
array to maintain this reference
voltage. If the power tracker is on,
this is the reference voltage from
which the inverter start exploring
voltages that produce more power. 37 Volts 400 600 300
PV Wakeup Voltage
Displays as:
PV V Start:
This is the trigger point that
transitions the inverter from PV
Sleep state to PV Wake Up state.
When the PV voltage reaches the
value of this parameter the
inverter transitions into PV Wake
Up mode. 38 Volts 440 600 300
