Viewing the Firmware Revision

The current firmware revision of the FLEXmax controller can be viewed on its own screen.
Return to the main menu screen.
From the status screen, press the first
soft key (SK1) to open the main
menu screen.
From the main menu screen, press
and hold <EXIT> (SK1). As long as
SK1 is held, it will show a Revision
screen with the current firmware
revision of the FLEXmax.

Extended Play Mode

If the MPP voltage is low enough to approach the battery voltage (usually when the PV array is very
hot), it is near the effective limit of the MPPT function. Side effects may cause the FLEXmax
components to make a squealing noise. Extended Play mode alleviates this problem by extending the
parameters of the MPPT sweep. (See page 98 for additional notes.)
To activate or deactivate the Extended Play feature:
Follow the instructions in Figure 51
for reaching the Revision screen.
While continuing to hold SK1, press
and hold SK3. After a few seconds,
the screen will toggle the status of
Extended Play and display it. X on
means the mode is on. If necessary,
continue to press and hold SK3 until
it reads X on.

The Secondary Stats screen shows the total accumulated DC and AC
kilowatt-hours and kiloamp-hours of the charge controller.
Pressing the <DCkWH> soft key switches the screen between
DC kilowatt-hours and AC kilowatt-hours.

DCkWH shows the DC kilowatt-hours and should be used in a system
that is not grid-interactive.

ACkWH is used with a grid-interactive system. This measure is based
kWHAC
on a 90% inverter efficiency (1 kWh DC= 0.9 kWh AC).
Pressing the <BACK> key three times returns to the main menu.
