Error Screen
From the Charge Controller Stats screen, the <Next> soft key proceeds to the Charge Controller Error screen.
This screen displays fault conditions for the FLEXmax Extreme. If an item displays Y, the error is active. Some
errors accompany a controller shutdown; others simply report status.
Figure 30 Error Screen
Temps Screen
From the Charge Controller Error screen, the <Next> soft key proceeds to the Charge Controller Temps screen.
This screen shows internal temperatures as measured at several locations in the controller. These measurements
are used for fan control, temperature derating, or to trigger a shutdown in extremely hot temperatures. If any of
these events occur, this screen can be used to check the temperatures.

Soft Keys:
<Back> returns to the previous screen.
<Port> cycles through each device connected to
the network.
Screen Items:
Output FETs The internal temperature as measured on the
controllers’s Field Effect Transistor (FET) heatsink.
Enclosure The internal temperature as measured on the
controller’s housing.
The list below shows the readings at which the FLEXmax
Extreme performs certain functions. See pages 10, 61, and 65.
Event Output FETs Enclosure
Over Temp error 130 78
Output derates 86 73

Soft Keys:
<DataLog> proceeds to the Datalog screen
(see page 33).
<Temps> proceeds to the Temps screen (see
Figure 31.)
<Back> returns to the previous screen.
<Port> cycles through each device connected
to the network.
Screen Items:
VOC Too High The PV array V
oc
has exceeded 145 Vdc and has
shut down. This error can clear automatically. (See the
Troubleshooting guide on page 61.)
Over Temperature The FLEXmax Extreme is too hot to operate
and has shut down. This error can clear automatically. (See the
Troubleshooting guide on page 61. Also see the temperature
readings in Figure 31.)
Shorted RTS The Remote Temperature Sensor (RTS) has
malfunctioned. This error will not shut down the controller, but
the controller cannot compensate for temperature while the
error is present. (See the Troubleshooting guide on page 61.)
Fault Input Active The External Fault terminals have detected an
open circuit. The controller has shut down. This is the only error
in this menu that illuminates the Fault indicator (see page 24).
This error requires a manual reset. See pages 18 and 19. This
error can also occur from an “Overcurrent” condition. (See the
Troubleshooting guide on page 61.)
Reduced Performance One of the two internal temperature
sensors (see below) has failed. If a failure is detected, the
FLEXmax Extreme will operate with a maximum output current
of 20 Adc.
