Adjustment of
initial reference
voltage
0.0–200.0V
MPPT begins to change from the reference voltage
Initial reference voltage =PV voltage-P15.25
For models of 220V, the default value is 5.0V.
For models of 380V, the default value is 10.0V.

P15.26
Upper and
lower limit time
of Vmppt
0.0–10.0s
When P15.26 is set to 0.0, the automatic
adjustment is invalid.
If it is not 0.0, the upper and lower limit of Vmppt
will be adjusted automatically after the time set by
P15.26. The medium value is the current bus
voltage and the limit is P15.27:
Maximum / Minimum reference voltage=Current
