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.

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).
