limit
0.0–10.0s
When P15.29=0.0, auto adjustment of
Vmppt upper/lower limit is invalid.
When it is not 0.0, Vmppt upper/lower
limit is automatically adjusted at an
interval specified byP15.29. The center
after the adjustment is the actual PV
voltage, and the upper/lower limit
adjustment range is P15.30. That is:
Max./Min. Reference voltage = (Actual
PV voltage ± P15.30
This will be automatically updated to
P15.26 and P15.27.
