Operation
Float Stage
This is a timed constant-voltage stage. It is sometimes known as maintenance charging. Float
stage balances the batteries’ tendency to self-discharge (as well as balancing the draw of any other
DC loads). It maintains the batteries at 100% of capacity.

Status message:
Float
Voltage Used:
Float voltage (V)
setting. For the three-stage cycle to proceed
normally, this setting should be kept higher than the
Refloat voltage (V)
setting.
Exiting to Idle:
Upon reaching the
Float time (m)
setting.
Time limit:
Float time (m)
setting. The timer begins running as soon as the charger exits
Absorption for any reason. The charger will go Idle once the timer has expired. The Float timer is
reset to its maximum amount whenever the batteries decrease to the
Refloat voltage (V)
setting.
To skip this step:
Decreasing the
Float time (m)
setting to zero causes the inverter to enter the Idle
condition as soon as the absorption stage is complete.
Setting
Float voltage (V)
equal to the
Absorb voltage (V)
level causes the charger to
proceed through the normal three-stage cycle, but at a single voltage.
Selecting a
Battery Series
that utilizes two-stage charging will limit the cycle to
performing only the Bulk and Absorption stages before exiting to Idle. See page 65.
Setting
Float charge mode
to
Disable
causes the inverter to enter Idle as soon as
the absorption stage is complete.
NOTE:
Setting
Float charge mode
to
Continuous
causes the charger remain in Float continuously
so that the Float timer no longer applies. The charger will still conduct a three-stage charge
if the criteria are met, after which it will return to continuous Float.
Idle
This is not a charging stage, but a period between stages. Following the expiration of the Float
timer, the unit enters (or re-enters) the Idle condition. The unit remains connected to the utility grid,
but the charger is inactive. The battery voltage will naturally decrease when not maintained by
another means such as a renewable source.

Status message: Idle
Voltage Used:
Refloat voltage (V)
setting.
Entering Refloat:
Upon reaching the
Refloat voltage (V)
setting.
To skip this step:
Setting
Float charge mode
to
Continuous
makes the charger remain in Float
continuously so that it does not enter Idle.
