P11.01
Frequency
decreasing at
sudden power
loss
0.00 – 1.00
(When the voltage degree is 400V, the corresponding power loss frequency
down voltage point of 0.85 is 460V)
0.85
P11.02
Frequency
decreasing ratio
at sudden power
loss
Setting range: 0.00 – P00.03 Hz/s
After the power loss of the grid, the bus voltage drops to the sudden
frequency-decreasing point, the controller begins to decrease the running
frequency at P11.02, to make the controller generate power again. The
returning power can maintain the bus voltage to ensure a rated running of the
controller until the recovery of power.

P15 Group: Special function parameters for PV inverters
P15.00 PV inverter
selection
0: Invalid
1: Enable
0: The function is invalid and the group of parameters cannot be used
1: The function is enabled and P15 parameters can be adjusted
1
P15.01
VMPP voltage
reference
0: Voltage reference
1: Max. power tracking
0 : Apply voltage reference mode. The reference is a fixed value and given by
P15.02.
1 : Apply the reference voltage of Max. power tracking. The voltage is
changing until the system is stable.
Note : If terminal 43 is valid, the function is invalid.

P15.02
VMPP voltage
keypad reference
0.0 – 6553.5V DC
If P15.01 is 0, the reference voltage is given by P15.02. (During test, reference
voltage should be lower than PV input voltage; otherwise, the system
will run at lower limit of frequency)
250.0V ○
P15.03
PI control
deviation
0.0 – 100.0% (100.0% corresponds to P15.02)
If the ratio percentage of real voltage to reference voltage, which is abs (bus
voltage-reference voltage) *100.0%/ reference voltage. If the value exceeds
the deviation limit of P15.03, PI adjustment is available, otherwise, there is no
PI adjustment and the value is defaulted to be 0.0% abs: the absolute value
0.0% ○
P15.04
Upper frequency
limit of PI output
P15.05 – 100.0% (100.0% corresponds to P00.03)
P15.04 is used to limit the Max. value of target frequency, 100.0% corresponds
to P00.03.
After PI adjustment, the target frequency cannot exceed the upper limit.

P15.05
Lower frequency
limit of PI output
0.0% – P15.04(100.0% corresponds to P00.03)
P15.05 is used to limit the Min. value of target frequency, 100.0% corresponds
to P00.03.
After PI adjustment, the target frequency cannot exceed the lower limit.
20.0% ○
P15.06 KP1
0.00 – 100.00
The proportion coefficient 1 of the target frequency
The bigger the value is, the stronger the effect and faster the adjustment.
