Dynamic Text
The text that appears on the second line of the charge mode screen is described
in Table 4-5.
Table 4 - 5 Dynamic Text
Text Appears When...
Charging The charge stage is Bulk, Absorb, or Float.
Not
Charging
Two-stage charging is selected and the solar charge controlleris
in the No Float stage.
Warning
Active
A warning condition is present (see Active Faults and Warnings
screen). For more information about the warning, press Enter to
view the Active Faults and Warnings screen.
Fault Active A fault condition is present (see Active Faults and Warnings
screen). For more information about the fault, press Enter to view
the Active Faults and Warnings screen.
Equalize
Due
The Equalize Reminder is set and the equalize reminder time has
elapsed.
Equalize
Pending
Equalization is activated, but equalization has not begun
because the unit is still in bulk or absorption.
mm:ss
Remaining
Equalization has begun, indicating how much time remains until
equalization is complete.
Standby
Mode
The MPPT is off because the solar charge controller has entered
Standby mode through the Device Menu or the SCP.
Hibernate The MPPT is off and Xanbus communications have stopped
because the solar charge controller has entered Hibernate mode
through the Device Menu or the SCP.
Restart
Pending
The solar charge controller is ready to restart but waiting for the
timeout period to expire. This condition is normally only observed
at dusk and dawn.
Low Light The solar charge controller cannot charge because the PV array
voltage is too low.
a
The Low Light message can appear during
any charge stage.
a.Battery voltage plus a factor of 0.25 V per 12 V. For example, in a 24 V system, if the bat-
tery voltage is 27.0 V and the PV array is producing 27.4 V, the Low Light message
appears. The Low Light message clears when the input voltage rises above the battery
voltage plus a factor of 1 V per 12 V.
Thermal
Derating
The solar charge controller is thermally derating its output
because its internal temperatures have exceeded their
recommended levels. This condition should only happen if the
unit is operating at full power and the ambient temperature
around the unit is very high (exceeding 45°C).
