To adjust these values and enhance the performance of these systems, use the MX60 ADVANCED
MENU to make changes. To determine your micro-hydro or fuel cell system’s best settings for MPP
voltage, do the following:
1. Use Auto Sweep and record the watts yielded. This value should be in line with your generator
capacity.
2. Switch to U-Pick % Voc mode and input di erent Park Mpp percentage values, checking the watts
value for each. This will require some experimentation.
• The MX60 can operate at any of the following xed percentages, selected in the Park Mpp
screen in the ADVANCED Menu selection:
40%, 50%, 67%, 70%, 72%, 75%, 76%, 77%, 78%, 80%, 81%, 83% or 85% of the measured
open circuit voltage
• The user will have to experiment with each of the 13 xed percentage values to
determine an appropriate xed percentage value. Typical xed values between 67% up to
78% have provided optimal results; however, each system is di erent and these xed
percentage values should be used as guidelines only
3. Compare the Auto Sweep and U-Pick % Voc values and determine which will best t
your system.
In addition to establishing the best mode and percentage values for determining the MPP voltage, a
user can also adjust the sweep interval and the range of values the MX60 uses to search for the MPP
voltage.
(If necessary, re-enter the system password 141 at any point while optimizing the system’s
performance.)
