GT
allows the FLEXmax to work more effectively with a grid-interactive OutBack inverter. This setting
automatically raises the charge controller’s Float voltage to equal its Absorption voltage. Since the
inverter sells power to maintain its own Float, Absorption, or Sell settings (all of which should be lower
than those of the controller), this mode makes it easier for the inverter to sell power. (See pages 47
and 104 for more information on this mode.)
NOTE
: The charge controller’s Float voltage returns to normal any time the inverter enters
PassThru
or
Silent
modes. (See the inverter Operator's Manual for inverter modes.)

The
Park Mpp
screen will be slightly different between
Auto Track
mode and
U-pick
mode. In the
U-pick
mode, the
Watts
will appear in addition to the
%Voc
value.
Figure 39 MPPT Mode – U-Pick %
The Mpp Range Limit % Voc adjusts the upper range limit
of the FLEXmax charge controller’s maximum power point
(MPP) tracking.
The default Max MPP voltage limit is set at 90% of the V
oc
and is normally not adjusted for a PV array. If necessary, the
adjustable limits are 80%, 85%, 90%, and 99% of the V
oc
.
Min optimizes the tracking window for MPPT. The default
Min setting of 1/2 establishes the lower limit of this window as
one-half the V
oc
.
The Min range limit setting may be set to FULL if something
other than a PV array is connected to the input of the
FLEXmax, such as a hydroelectric turbine (see page 102).
However, the input voltage must never exceed 150 Vdc at
any time.
