Wind Track
This mode uses a power curve that is either built by the user or one of the pre-installed graphs. The power
curve consists of 16 set points that consist of output amperage and input voltage, allowing the user to
custom build a curve for their Wind turbine. Please refer to the Wind section of the manual for full details
on programming the curve as well as our video that will help in understanding how to adjust these curves
using the wind graph editor.
Dynamic
This is typically used for PV (solar) input sources and tries to follow, on a slow dynamic basis, the
changing conditions of the input source. This mode has one user adjustment which is a forced sweep
perturb trigger interval for times when the input condition changes do not trigger a dynamic sweep. The
interval is in units of minutes.
U-Set VOC%
This is a fully manual mode based on a percentage of VOC. The Classic will sweep based on the user set
time in minutes and then park at a user set % of the VOC the Classic found on that sweep. This mode is
useful for testing or constant voltage sources.
Note: Mode must be manually turned ON after changing the mode. To turn the Mode on highlight the
OFF under ON/OFF and switch it to ON. Press enter to save this change.
Configuring the Classic for Wind Input Source
Wind
If you selected “Wind” you will need to select a power curve from the list of pre-loaded curves or build
your own. To access the list of power curves follow the steps below.
 Push the Main Menu button.
 Scroll left or right until “Mode” is highlighted and push the Enter button.
 Set the status to OFF and then use the right soft key to select “Graph”.
Using the left soft key select “MEM”. Now you can scroll up and down through the menu and select from
the curve that was designed for your turbine. Once you find the correct power curve use the right soft key
to select “RECALL”. Now push the Enter button to save this power curve to the Classics memory.
There are also 9 memory spaces for you to save a custom power curve. To build custom power curves
select a memory location between 1 and 9 and hit “RECALL”. Use the right and left arrow buttons to
scroll through the 16 steps in the custom curve. On each step you can set the amperage by using the up
and down buttons. When you have the power curve the way you want it select “MEM”. Use the up and
down buttons to select a location 1 through 9 to save it in and select “SAVE”. Now push the Enter button
to save it to the Classic's memory.
