Name Detailed illustration of parameters
0 means to apply voltage reference
mode. The reference is a fixed value and
given by P15.02.
1 means to 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.
0.0~6553.5Vdc
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).
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, 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: absolute value
P15.05~100.0% (100.0% corresponds to
P00.03)
P15.04 is used to limit the Max. value of
