Multi-Stage Charging Process
The charging cycle uses a multi-stage charging process to maintain the
batteries. Whenever AC power that is within the range of the inverter’s
settings is present at the inverter’s input, it passes power through to the
connected load and begins charging the batteries, indicated by the Bulk or
Float charge indicator LED on the control module.
Figure 6-2
Multi-Stage Battery Charging Process
Bulk Stage
Bulk charge is the first stage in the charging process and provides the
batteries with a controlled, constant current. Once the battery voltage rises
to the bulk voltage threshold, the charger switches to the Absorption
Stage.
Important:
The default settings of the
Sine Wave Plus
may or may not work
for your specific installation. Take the time to review the default settings to make
sure they are appropriate for your installation. If not, you will need to adjust the
settings according to the battery manufacturer’s recommendations. The following
information is provided to help you make the necessary calculations.
Note:
This information is provided for guidance only. Variations in battery
chemistry, as well as, site specific environmental considerations mean that you
should consult your system designer or battery manufacturer for specific
recommendations for appropriate battery voltage and current settings.
If a generator was automatically
started by the inverter to charge
the batteries, it will shut off
when the charger reaches the
FINISH stage after the bulk/
absorption period.
(GENERATOR must be in
AUTO MODE).
