Description
Range
Active power rising
gradient
The rise rate of inverter active
power per minute.
1%/min~6000%/min
Active power setting
persistence
Switch for enabling/disabling
the function of saving output
limited power.
Enable/Disable
Active power limit
The switch for limiting output
power.
Enable/Disable
Active power limit ratio
The ratio of limiting output
power to rated power in
percentage.
0%~110%
Shutdown when active
power limit to 0%
Switch used to determine
whether the inverter is in stop
state when the limited power
reaches 0.
Enable/Disable
100% Scheduling to
achieve active
overload
Switch used to ensure that the
inverter operates at the maxi-
mum active power when PV
power limit ratio is set over
100%.
Enable/Disable
The inverter provides the reactive power regulation function. Enable this function under Re-
active Power Regulation Mode and select the appropriate mode.
table 7-8 Descriptions of reactive power regulation mode:
Mode
Descriptions
Off The PF is fixed at +1.000.
PF
The reactive power can be regulated by the parameter PF (Power Factor).
Qt
The reactive power can be regulated by the parameter Q-Var limits (in %).
Q(P) The PF changes with the output power of the inverter.
Q(U) The reactive power changes with the grid voltage.
“Off” Mode
The reactive power regulation function is disabled. The PF is limited to +1.000.
“PF” Mode
The power factor is fixed and reactive power setpoint is calculated according to the current
power. The range of PF is (-1.0 to -0.8) and (+0.8 to +1.0).
Leading: the inverter is sourcing reactive power to the grid.
Lagging: the inverter is injecting reactive power into the grid.
