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 1741
requirements.

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.

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.

Time Delay for PV
Wake up
Displays as:
PV T Start:
Time delay to transition from PV
wake up state to PV On-line state.
Once the inverter is in PV Wake
Up mode, it waits for the amount
of time determine by this
parameter before transitioning into
PV on-line mode. During this time
the inverter checks that the PV
voltage is no less than the PV
wake voltage, otherwise it goes
into PV Sleep mode.

Time delay for PV
Sleep Test
Displays as:
PV T Stop:
This is the amount of time the
inverter will be in Sleep Test mode
if the output power continues to be
below “PV P Stop”. The inverter
will exit Sleep Test mode towards
on-line mode is the power is over
“PV P Stop” or towards Shutdown
mode is the “PV T Stop” timer
expires.
