
Charge
displays the kilowatts and AC amperage consumed for the inverter to charge the ba
ttery
ban
k. This line also shows the present charging stag
e.

Load
displays kilowatts and AC amperage consumed by devices on the inverter’s output. It can be
the same a
s
Invert
.

Buy
displays the kilowatts and AC amperage brought into the inverter’s input for both charging
and
load
s. This is usually a total of
Charge
and
Load
.

Battery
displays the uncompensated ba
ttery voltage.

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
.

AC In
displays the AC voltage measured at the inverter’s input from an AC source (the sum of
the L1
and L2 readi
ngs). This number may be erratic or inaccurate upon first connectio
n until the inverter
synchro
nizes with the input
source.

AUX
displays the current status of the inverter’s Auxiliary (
A
UX
) 12-volt output.
Relay
displays the
curre
nt status of the inverter’s
A
UX
relay contacts. (See page 39.)

A diode symbol may appear to the left of the screen name to indicate “diode charging” mode. This is
a mode that a
llows 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:

Actual
displays the uncompensated battery voltage.

Absorb
displays the charger’s Absorption voltage setting. (See page 29.)

Float
displays the charger’s Float voltage setting. (See page 30.)

Equalize
displays the charger’s Equalization voltage setting. (See page 32.)

Temp Comp
displays the corrected battery voltage using temperature reading
s from the RTS. If no
R
TS is present,
Temp Comp
and
Actual
will read the same. (See page 34.)

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 characte
rs ### will
be displayed.

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
.)

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 an
d 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 arro
w 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.
