Soft Keys: Charge Controller
Charge Controller Soft Key
The <Charge Controller> soft key (A) brings up FLEXmax charge controller
o
status data. If no charge controller is present, the PV icon is blank and this soft key
is inoperative.
The reading above this key shows the PV kilowatts used to charge the battery.
A
Screen Items (A):
The upper left corner of the screen shows the present mode of operation
(Bulk, Absorb, Float, EQ, or Silent).
In: The present PV array operating voltage and the current harvested from the array.
VOC: The available PV open-circuit voltage.
Out: The present battery voltage and the controller(s) battery charging current.
This line also displays the daily accumulated kilowatt-hours and amp-hours.
Operating: The total hours the charger has operated that day in any stage.
Float and Absorb: The run time of the timers when in either stage.
Maximum: The maximum daily PV current and wattage and the recorded times.
The lower right corner shows the current status of the charge controller's Auxiliary (AUX)
output. (See the MATE3s Programming Guide and the charge controller manual.)
o
The <DataLog> soft key (B) brings up the Charge Controller Datalog screen.
It maintains a continuous daily log (up to 128 days) of amp-hour and watt-hour statistics,
as well as maximum current, wattage, and maximum and minimum voltage figures. One
day can be displayed at a time.
Screen Items (B):
Max Output: The maximum daily current and wattage.
Absorb and Float: The amount either of these timers ran that day.
High VOC: The highest daily open-circuit voltage (VOC).
Min Batt and Max Batt: The lowest and highest daily battery voltage.
The upper left corner shows the date of the selected DataLog.
(The present DataLog screen reads Today.)
The <-Day> soft key (E) brings up the previous day's log. Instead of Today, a date is shown.
Similarly, the <+Day> soft key (D) advances the log by one day. (If Today is displayed,
it does nothing.) This line also displays the daily accumulated kilowatt-hours and amp-hours.
o
The <Graph> soft key (C) brings up screens that plot different kinds of
charge controller information. Shown here is the first Graph screen.
This screen shows changes in PV wattage over time.
The <Next> soft key (F) brings up a Graph screen (not shown) with changes in
battery voltage over time. This graph may be used by other soft keys as well.
Continuing to press <Next> brings up a Graph screen with changes in
PV voltage over time.

Hot Keys
Six "hot" keys display the most common operational screens. Some screens have selectable modes
(On, Off, etc.) while some show function status. Some screens have their own soft keys and menus. The
measurements and status messages are collective readings for the system, not for an individual inverter,
unless specified otherwise. Similarly, commands are usually global unless specified otherwise.
INVERTER
The INVERTER hot key (A) brings up Inverter
Status, with mode commands and readings.
In a stacked system, the mode commands are
global. Kilowatt readings are a total of all inverter
measurements. Kilowatt-hour readings are daily
accumulations which are reset to zero at
midnight. All voltage readings are taken from
the master inverter.
In Radian-class or FX-class models, INVERTER
brings up screen A1. In FXR-class models,
INVERTER brings up screen A2.
The <On> and <Off> soft keys (B or C) send On or Off commands to all
o
inverters. The <Search> soft key (D) toggles in or out of Search mode.
o
Mode: This displays the soft key selection (On, Off, or Search) using
soft keys B, C, or D.
Screen Items (A1):
Battery: The measured battery voltage, not compensated for temperature.
Input: The AC source voltage and the power in kilowatts from the source.
Output: The voltage measured at the inverter's output and the kilowatts
produced. The produced power may equal the load wattage, but can also
include power sold to the grid.
Load displays the kilowatts delivered to the inverter's output.
Screen Items (A2):
AC In: The input source voltage. This line also displays kilowatt and kilowatt-hour readings.
A kilowatt reading under To means the inverter is exporting (selling) power to the AC input. This only occurs in grid-interactive
applications (with the inverter's Grid Tied mode). A To kilowatt-hour reading is the daily energy sold by the system.
A kilowatt reading under From means the inverter system is importing (buying) AC power from the source, either for charging or
for loads. A From kilowatt-hour reading is the daily energy imported by the system.
AC Out: The voltage measured at the inverter's output. This line also displays kilowatt and kilowatt-hour readings.
A kilowatt reading under To means power is delivered to the AC output for loads. This may be inverted power (as shown under
Batt) if no AC source is present. If a source is present, it may mean either offset power (see Batt) or power imported from the AC
source (see AC In). A To kilowatt-hour reading is the daily energy delivered by the system.
A kilowatt or kilowatt-hour reading under From is power received from the AC loads. This only occurs in AC Coupling applications.
Batt: The measured battery voltage, not compensated for temperature. This line also displays kilowatt and kilowatt-hour readings.
A kilowatt reading under To means the inverter is delivering power to charge the batteries. This is imported power from the AC
source (see AC In). A To kilowatt-hour reading is the daily charging energy delivered by the system.
A kilowatt reading under From means the inverter is converting battery power to AC. If no AC source is present, this is inverted
power used to operate loads (see AC Out). If an AC source is present, this may be either offset power (see AC Out), or power
sold to the AC source (see AC In). A From kilowatt-hour reading is the daily energy delivered from the batteries.
