Restart Mode
This setting allows the user to choose between continuous maximum power point (MPP) tracking, or occasional
restarts of the sweeping process. A restart means the controller abandons the existing maximum power point
value it was using and “re-sweeps”, or begins gathering new power point data. (See page 70 for more
information on MPP tracking.)
ReStart Mode has three options available:
 Mode 0 – Initial sweep only and then continuous MPP tracking. ReStart is disabled. The FLEXmax will
continously track the maximum power point without starting over.
 Mode 1 – Automatic re-sweep every 90 minutes if controller is in MPPT operation. This will not reset any
counters, charging stages, or statistics.
 Mode 2 – Automatic re-sweep every 90 minutes if controller is in any charging mode. This will not reset any
counters, charging stages, or statistics.

Calibrate
The Calibrate menu allows adjustment of the controller’s battery voltmeter. If a particular controller’s readings
do not match those of another device or a hand-held meter, the calibration feature may improve consistency.
Figure 45 Calibrate
NOTE: Calibration does not change the actual voltage of the charge controller, only the reading of that voltage.
Also, measurements in places other than the charge controller’s terminals may differ regardless of calibration.
For example, it is possible to get a different reading at the charge controller’s DC terminals than on the batteries.
Connection problems, corrosion, and the effects of induction and resistance may all result in voltage differences.
If this occurs, it is an issue with the system, not the charge controller. Calibration cannot correct for it.
Also note that this function does not affect voltages displayed by the MATE3 from other sources such as the
FLEXnet DC Battery Monitor or an inverter
. It also does not affect voltages displayed using the FLEXmax Extreme
Battery Sense terminals (see page 18). If any of these readings are displayed on the MATE3, adjusting the
Calibrate menu will have no effect.
Reset Charge Controller to Factory Defaults
This menu allows the user to erase all settings from the selected charge controller and start over with the values
programmed at the factory. These values are listed on page 66. This procedure is recommended any time the
controller is relocated or the system is substantially revised.
This procedure is a requirement for resetting the nominal battery voltage of the system (see page 21).
Calibration Offset
Set Points:
 Battery Voltage – Calibrates the Vdc measurement
made at the controller’s battery terminals
Set Points:
 0 – Continuous MPPT, 1 – Automatic re-sweep every 90 minutes
in MPPT charging, 2 – Automatic re-sweep every 90 minutes in
any mode.
