MATE3 System Display and Controller
Figure 26 Display and LED Status Indicators
The MATE3 System Display and Controller is a display which allows the user to read the operating mode,
measurements, and any status messages from the FLEXmax Extreme charge controller. It can also change the
charge controller’s settings when the default settings are not enough.
Battery Status Indicators
Three LED indicators provide a visual reference to indicate the condition of the battery bank.
 A GREEN LED means the batteries have an adequate charge at that time. It does not always mean they are
full. If the FLEXnet DC battery monitor is installed, this means the batteries are
 80% State of Charge (SOC).
 A YELLOW LED means the batteries are somewhat discharged. If the FLEXnet DC is installed, this means the
batteries are
 60% and  70%.
 A RED LED means the batteries are greatly discharged and may require attention. If the FLEXnet DC is
installed, this means the batteries are < 60%.

Battery Status
GREEN 12.5 Vdc or higher 25.0 Vdc or higher 37.5 Vdc or higher 50.0 Vdc or higher ACCEPTABLE
YELLOW 11.5 to 12.4 Vdc 23.0 to 24.8 Vdc 34.5 to 37.2 Vdc 46.0 to 49.6 Vdc MARGINAL
RED 11.4 Vdc or lower 22.8 Vdc or lower 34.2 Vdc or lower 45.6 Vdc or lower LOW
NOTES:
 Gaps in the table (higher-voltage units) are due to the resolution of the charge controller’s DC meter.
 The Battery LED settings cannot be changed.
 Voltages higher than shown in the GREEN row usually means that the batteries are charging.
Charger Indicator
The MATE3 is equipped with several LED indicators denoting status. The Charger indicator (see Figure 26) will
illuminate if the charge controller is delivering more than a minimal amount of charging power to the batteries.
It will flash if the charge controller is equalizing the batteries.
NOTE: The Charger indicator will illuminate for any device on the HUB Communications Manager that is
charging, including OutBack inverters. If a FLEXmax Extreme charge controller is accompanied by other devices,
this indicator may indicate charging by any device, not just that controller.
