U-Pick % (Voc) MPPT mode operates the PV voltage at a
user-selected percentage of the VOC which is displayed
in the Park Mpp % Voc screen. Press the <NEXT> soft key
to view the Mpp Range Limit % screen.
The Mpp Range Limit % Voc adjusts the upper Mpp limit of
the VOC. The default Charge Controller MPP voltage limit
is set at 90% of the VOC and is normally left alone for an
array. Setting min to 1/2 reduces the initial tracking time
on a high input voltage array and also tracks one-half the
VOC voltage.
The MPP adjustable Charge Controller limits are 80%,
85%, 90%, and 99% of the VOC. The min range limit set-
ting may be set to FULL if something other than a PV
array is connected to the input of the Charge Control-
ler, such as a micro-hydro generator (see page 58), but
the VOC cannot exceed 150 VDC at any time. Press the
<min> or <max> soft key to adjust the MPP range limit.
When done, press the <NEXT> soft key to view the
Absorb Time screen.
Use ½ value for high input arrays
to speed up initial tracking.
