CHARGING (Blue):
Illuminates when more than 10 watts of PV power is available. It is solid or
flashing depending on the charging stage. The system display represents
these stages as operating modes in the
STATUS menu. See page 36 for a
list of modes. See page
69 for a description of charging stages.
Solid
: Bulk or Equalization charging.
•
Accompanied by
S
TATUS
indicator . See below for colors.
Flashing
: Absorption or Float charging.
•
Accompanied by amber
S
TATUS
indicator in Absorption stage.
•
Accompanied by green
S
TATUS
indicator in Float stage.
•
Will continue flashing in these modes even if less than 10 watts
is available.
•
The
STATUS
indicator flashes during power-up to indicate nominal
voltage. See page 27. It may briefly illuminate at other times when
not charging. See Table 4 on page 34.
Off
: Less than 10 watts of PV power is available.
STATUS (Tri-color Red, Green, or Amber):
Indicate either battery voltage or charger status. See
Table 2 on page 29.
NOTE
: Amber is a mixture of the red and green colors.
Amber (solid):
The battery voltage is equal or greater than 1.91 volts
per cell (Vpc).
• Usually indicates Bulk or Absorption stage.
•
Accompanied by solid blue
C
HARGING
indicator in Bulk stage.
•
Accompanied by flashing
C
HARGING
indicator in Absorption stage.
Green (solid)
: The unit has entered Float stage.
• It will remain green regardless of voltage until it falls below 2.08 Vpc. This will trigger a new charge cycle.
•
Accompanied by flashing blue
C
HARGING
indicator .
Green (flashing)
: Indicates Grid-Tie mode. See page 44.

May also flash amber/red. See pages 33 and 70.
Red (solid)
: The batteries are less than 1.91 Vpc. This indicates that the batteries are severely discharged.
Red (flashing)
: The batteries are less than 1.75 Vpc. This indicates that the batteries are critically discharged.
•
These states do not indicate the charging stage. It may still be shown by the blue
C
HARGING
indicator.
A
UX
(Yellow):
•
Solid
: The
A
UX
output is active.
F
AULT
(Red):
•
Solid
: The GFDI circuit has shut down the charge controller. See page 13 for more information. If the
system display is present, it will deliver a
GFDI Fault
error message (see page 38). See Table 7
beginning on page 55 for information on resetting this error.
•
Flashing
: The AFCI circuit has shut down the charge controller. See page 21 for more information. If the
system display is present, it will deliver an
Arc Fault
error message (see page 38). See Table 7 beginning
on page 55 for information on resetting this error.
•
If both faults are active, this indicator will be solid. A GFDI fault overrides other indications.
NOTE
: All indicators will flash twice to indicate a Rapid Shutdown. See page 18 and 24 for information.
Most of the indicators will then go out until the Rapid Shutdown is reset. See page 25
. If the system display is
present, it will deliver a
Fault Input Active
error message (see page 38).
