voltage=Current PV voltge±P15.30 and it
will update to P15.26 and P15.27 at the
same time.
5.0~100.0V
Adjustment of the upper and lower limits
P15.27~6553.5V
The upper limit cannot exceed the
P15.28 when Vmppt is the maximum
value.
During the maximum power tracking, the
upper limit of the solar cell panel
Vmppt
reference voltage will not exceed the
value set by P15.31. The factory value
depends on the model. By default, the
value for the -4 models is 750V and the
value for other models is 400V.
0: Automatic shift
1: Power frequency input
2: PV input
If the value is 0, the system will switch
between PV input and power frequency
input according to the detected PV
voltage and threshold;
If the value is 1, the system will force to
switch to power frequency input;
If the value is 2, the system will force to
switch to PV input.
Note: When the terminal input 42 is
