x Charge
displays the kilowatts and AC amperage consumed for the inverter to charge the battery
bank. This line also shows the present charging stage.
x Load displays kilowatts and AC amperage consumed by devices on the inverter’s output. It can be
the same as Invert .
x Buy displays the kilowatts and AC amperage brought into the inverter’s input for both charging and
loads. This is usually a total of Charge and Load .
x Battery displays the uncompensated battery voltage.
x AC Out displays the AC voltage measured at the inverter’s output (the sum of the L1 and L2
readings). If an AC source is present, this reading is usually the same as AC In .
x
AC In
displays the AC voltage measured at the inverter’s input from an AC source (the sum of the L1
and L2 readings). This number may be erratic or inaccurate upon first connection until the inverter
synchronizes with the input source.
x AUX displays the current status of the inverter’s Auxiliary ( A
UX
) 12-volt output. Relay displays the
current status of the inverter’s A
UX
relay contacts. (See page 39.)
x A diode symbol may appear to the left of the screen name to indicate “diode charging” mode. This is
a mode that allows fine control of charging, selling, and load support. It does not visibly affect
operation.
From either L1 Phase or L2 Phase , the <Graph> soft key brings up a series of screens which
plot various types of data over time on the system display screen.
Battery Screen
From the L2 Phase screen, the <Next> soft key brings up a screen showing charger status,
charger settings, and battery voltage and temperature information.
Figure 9 Battery Screen
Screen items:
x Actual displays the uncompensated battery voltage.
x Absorb displays the charger’s Absorption voltage setting. (See page 29.)
x Float displays the charger’s Float voltage setting. (See page 30.)
x Equalize displays the charger’s Equalization voltage setting. (See page 32.)
x Temp Comp displays the corrected battery voltage using temperature readings from the RTS. If no
RTS is present, Temp Comp and Actual will read the same. (See page 34.)
x Batt Temp displays the battery temperature in degrees Celsius, as measured by the RTS. It is only
valid for port 1 on the HUB. If other ports are selected, or if no RTS is present, the characters ### will
be displayed.
x Re-Float
displays the Re-Float setting which was programmed into the inverter’s charger. This is the
voltage used for the inverter to return from Silent mode to the float stage. (See page 30.)
x Sell RE voltage is the target voltage used by the inverter for the grid-interactive and other Offset
functions when the charger is otherwise inactive. (See pages 14 and 36.)
The <
Warn
> and <
Error
> keys bring up various fault screens. See the next section.
NOTE
: The charger settings cannot be adjusted on this screen.
An arrow will appear to the right of Absorb , Float , or Equalize
to indicate that the charger is in that stage. The arrow will not
appear if the charger is in the Bulk stage, or if it is inactive.
