0.00–1.00
Used to set the min. reference voltage in
max. power tracking. Min. reference
voltage in max. power tracking =
(Open-circuit voltage of photovoltaic
panels) * P15.26. Open-circuit voltage of
photovoltaic panels = P15.25 + P15.28
Track the max. power in the range of Min.
reference voltage in max. power tracking–
P15.27. P15.27 must be greater than the
min. reference voltage. A smaller difference
between them indicates a smaller range,
which means faster tracking. The voltage
corresponding to the max. power must be
within the range. P15.26 and P15.27 must
be adjusted according to the site situation.
Min. reference voltage in max. power
tracking–P15.31
It is the max. voltage tracked when MPPT
max. power tracking is valid.
The factory value depends on the model.
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 by P15.29. The center after the
