The OutBack MATE includes a SUMMARY screen to allow easy understanding of the FX operation.  The display uses both words and 
symbols to show what currently is happening in the system, along with a limited amount of numbers.  This makes it easier for the 
system user to understand where the power is flowing within the system.  The first line of the summary screen displays “DCÅÆAC” 
and is measured in kilowatts (kW).  This is to indicate the approximate AC power that is being both produced and consumed by all the 
FX’s connected to the MATE (multiple FX’s can be connected to one MATE through the HUB).  Basically, it shows how much work the 
FX’s are doing and relates to energy being transferred between the FX’s and the batteries.  The second line of the summary screen 
displays ”AC Load”  and has a light bulb symbol that appears for every 500 watts of power per FX that is being delivered to the AC 
loads (so 1 one light bulb equals 1kW when two inverters are used with a single MATE).  The third line displays four different things 
depending of the status of the AC input.  It displays “No ACIN” when the FX doesn’t sense an AC source present.  It displays “AC Drop” 
when an AC source is present but not connected.  It displays “Buying” when an AC source is connected and the FX is using the source 
to charge or pass-through to the loads.  Finally, it displays “Selling” when the FX is pushing power back into the AC source (Grid-Tie 
FX’s only).  In the third line, the symbol used to denote 500 watts or power per inverter is a dollar sign.  The fourth line of the summary 
screen provides information about the battery (limited to battery voltage at this time).  

To access the summary screen, press the button under the label SUM from the MAIN screen.  Included below are some examples of 
different summary screens with an explanation of the information represented.

The MAIN screen is where the menu system starts.  The four words in the bottom line of the 
display correspond to the four buttons located below the display. The word in BOLD on the 
bottom line indicates the selection used to advance the display to the next screen.  Pressing 
the left two buttons simultaneously from anywhere in the menu will return you to this screen. 
 

To access the summary screen, select SUM from the MAIN screen.  A typical summary screen 
is shown here for a FX when the inverter is off and no AC source is connected. 

The battery voltage is provided in the lower right corner of the display.    

 
                        EXAMPLES

 

 
INVERTING:

 The FX is inverting and producing AC output voltage which is powering 1.4kW of 

AC loads.  No AC source is connected to the inverter.   
 
  
 
PASS-THROUGH:

 An AC source has been connected and the AC loads are drawing power 

from the AC source that is passing through the FX.   The top line shows 0.0 kW indicating that 
the charger is in SILENT mode and is not charging the batteries.  Approximately 1.0 kW loads 
are being powered from the AC source (assuming the system consists of one FX). 
 
BUYING (CHARGING & PASS-THROUGH):

 The FX is buying (four $ ≈ 2.0kW) more power 

than it is delivering to the loads (one ☼ ≈ 0.5kW). This is an indication that the FX is using the 
excess power to charge the batteries.  The charger is charging at a rate of 1.7 kW of AC power 
going into the battery.  The AC loads are low and are being powered from the AC source.   

 The inverter is on and powering 2.5 kW of AC load from the batteries.  The AC 

source is available but DROP was selected in the AC INPUT CONTROL.  This will also be 
displayed when an AC source is available but not in use, such as during the initial time delay 
period once an AC source has been connected.   
 
SELLING: 

The FX is selling power back to the utility grid at about 1.5kW.  It is also supplying 

about 0.5kW of AC loads.   The FX is taking about 2.2kW of power from the batteries.  This 
excess battery power is coming from a different source (solar, wind, hydro, etc).  This screen 
will only appear on “Grid-Tie” FX’s.
