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.
