in minutes, and sweeps around the present (i.e., the last found) MPP Voltage. The range of
this sweep is determined by the Sweep Depth user adjustment and is expressed as a
percentage of watts that the sweep started from. For example, if in Legacy P&O mode, the
Classic was outputting 500W and the Sweep Depth percentage was set for 10% (50W), the
sweep will bring the input voltage down until the output power drops down to 450W, then
will sweep up in voltage until the power drops again down to 450W and then go back to the
newly found MPP Voltage, waiting for the next sweep.
Wind Track
This mode uses a wind 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 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 percentage 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. Depress ENTER to save this change.
Programming the Classic for Wind Input Source
AUX 2 needs to be programmed for the Classic to work with the Clipper.
Enter the MAIN MENU and scroll to AUX, then depress the ENTER key.
Scroll to the right to highlight the text under AUX 2 and depress the RIGHT SOFT key.
Scroll up or down to find Clipper Control and depress the RIGHT SOFT key again.
On this screen, select either AC or DC to match the Clipper being used (AC is default).
Depress the RIGHT SOFT key again, set the absolute maximum voltage you want the Clipper
to allow before clipping occurs.
Depress ENTER to save this data.
Depress MAIN MENU until you get back to the AUX 1 and AUX 2 screen.
Set the text under AUX 2 to read Clipper Control, depress ENTER.
Press STATUS to return to the home screen.
NOTE: See our instructional videos at www.midnitesolar.com.
CAUTION: Connecting a DC Clipper with this set to AC can damage the Clipper.
