NOTE: If the Slope setting is adjusted to any specialized value other than 5 mV, the system display will
communicate this value to other networked OutBack devices. The other devices will use the same value.
This system-wide compensation only works if there is a single RTS on the system and it is connected to
the FLEXmax 100.
In all cases, the batteries should be monitored to ensure they are being charged according to the battery
manufacturer’s recommendations.
Battery Equalize
CAUTION: Battery Damage
 Do not equalize any sealed battery types (VRLA, AGM, Gel, or other) unless approved by the
manufacturer. Some batteries may suffer severe damage from equalization.
 Contact the battery manufacturer for recommendations on equalization voltage, duration,
schedule, and/or advisability. Always follow manufacturer recommendations for equalization.
Equalization is a controlled overcharge that is part of regular battery maintenance. See pages 33 and 68
for an explanation of equalization. The Battery Equalize screen allows the user to control the settings for
the equalization process.
Figure 40 Battery Equalize
Equalization can be triggered manually with the main button. (See pages 33 and 68.) Equalization can
also be triggered automatically on a schedule. The Days setting controls this schedule, setting a delay of
the appropriate number of days between the end of one cycle and the beginning of the next. If this item is
set to zero, the controller will not perform automatic equalization.
Grid-Tie Mode
IMPORTANT:
 This mode requires an OutBack grid-interactive inverter (also known as grid-tie enabled) with
its sel
ling mode enabled. Not all inverters are grid-interactive. If the sy
stem is connected to
an inverter that is
not grid-interactive or not enabled, Grid-Tie mode w
ill not function.
 This mode requires both the inverter and the charge controller to be connected to the HUB for
communication. It also requires a
MATE3s system display. If an OutBack grid-interac
tive
inverter is presen
t but these devices are not on the HUB, Grid-Tie mode w
ill not function.
Grid-Tie mode allows the FLEXmax 100 to work more effectively with any grid-interactive inverter
installed on the HUB. This mode automatically raises the controller’s Float voltage to equal its Absorption
voltage. Since the inverter sells power to maintain its own Float, Absorption, or Sell settings (all of which
should be lower than the FLEXmax), this mode makes maximum power available for the system to sell.
See page 71 for more information on this mode.
