Parameter
Description
Vmppt-max (V)
Maximum MPPT voltage
Vmppt-min (V)
Minimum MPPT voltage
T-start-wait (s)
The time from the AC/DC parameters meet the grid-connection
conditions to the MV Station begins to generate power.
T-stop-delay (s)
The time from the LCD display or upper computer sends stop
command to MV Station performs the stop command
Stop slope (%/s)
Active power decline rate from MV Station performs stop
command to MV Station stops
Limit Power (%)
Percentage that the active power output accounted for the
nominal output power (%)
Pf
cosφ
Q-limit (%)
Percentage that the reactive power rise accounted for the
nominal power (%)
Q-adjust switch
Refer to 10.3
Power-off saved (Pf)
If the power factor setting can be saved when the LCD screen is
powered off
Power-off
saved
(P-limited)
If the limit power(%) setting can be saved when the LCD screen
is powered off
SVG switch **
If the reactive power compensation is activated or deactivated
T-recover (s)
Automatic recovery time when fault occurs
P-rise rate (%/s)
Percentage that the active power rise per second accounted for
the nominal power (%/s)
P-decline rate (%/s)
Percentage that the active power decline per second accounted
for the nominal power (%/s)
Q-rise rate (%/s)
Rate of rise of the reactive power
Q-decline rate (%/s)
Rate of decline of the reactive power
Trip Enable
Trip the DC main switches of two modules
Fgird-derating
control
switch
Control switch for over-frequency derating
Fgird-derating start(Hz)
Start frequency for over-frequency derating (the Fgrid-derating
control switch is on)
Fgird-derating kap(%Hz)
Derating

Fgrid-derating control switch is on)
** at night when the MV Station enters standby mode (but not enters the deeper standby
mode with lower power consumption), the SVG function needs to be activated: first stop the
MV Station by the LCD button a
nd then start; set the SVG switch to “Enable”. The SVG is
an optional function for this MV Station.
