Floating
The system display shows this message for the Float stage of a three-stage charging cycle. In this stage,
the FLEXmax 100 regulates the battery voltage at the Float Voltage set point. This stage is temperature-
compensated. (See page 68.) Float is a constant-voltage, variable-current charging stage. It usually
involves a minimal (maintenance) current flow. However, it may deliver no current and still display Float if
another source maintains the batteries above the Float Voltage.
If the battery voltage drops below the Float Voltage, the FLEXmax 100 will employ the MPPT function to
draw more power from the PV array. (This may occur if the batteries are powering loads.) If this occurs,
the operation may change to constant-current, variable-voltage. The mode will still show Float.

EQ
The system display shows this message if the charger is in a cycle of equalization. (See page 68 for an
explanation of equalization.)
Before equalizing, battery loads should be minimized and the battery should be charged so the charge
controller can quickly reach the Equalization Voltage set point. (See page 44.) Otherwise, the charge
controller may have difficulty reaching or maintaining the equalization process.
Equalization is not battery temperature compensated.
Figure 24 LED Indicators (Equalization)
Blue (flash on ½ second, off 2 seconds)
Green (solid)
This indicator will remain green if the voltage rises or drops, unless
it decreases below 2.08 Vpc. This will trigger a new charge cycle.
Blue (solid)
Amber/green (alternating once per second)
This indicator will alternate amber and red if the batteries are below 1.75 Vpc
while equalizing. This is usually a temporary condition.
