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 44 Calibrate
NOTE
: Calibration does not change the actual voltage of the charge controller, only the voltage reading.
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 shown by the system display from other sources such
as the FLEXnet DC Battery Monitor or an inverter. It also does not affect voltages displayed using the
FLEXmax 100 Battery Sense terminals (see page 21). If any of these readings are shown on the system
display, adjusting the
Calibrate
screen 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 62. 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 26).

To access the
Reset to Factory Defaults
menu:
1. Access the main menu as shown on page 41.
2. Select the
Settings
screen. (This option may be
highlighted by default.)
3. Select
Charge Controller
in the device
Settings
menu.
4. Select the

screen.
5. Use the soft keys to select
No
or
Yes
.
If <

Charge Controller
menu. No changes will be made
to any settings.
If <

immediately change to the original factory values.
The screen will display the message
Charge
Controller Restored to Factory Defaults.
A <

key will return the screen to
Charge Controller

6. After resetting the charge controller to factory default
parameters, turn all power to the controller (PV and
battery) off and then on again.
