Battery Charger Functions

When AC power is available, the Freedom SW can operate as
a battery charger. Different battery types and chemistries
require different charging voltage levels. Not charging
batteries at the required levels can shorten battery life or
damage the batteries. The Freedom SW is configured at the
factory to work with the battery types recommended for
inverter applications. If the default settings do not work for
your specific installation, you can adjust the charge stage
settings (as recommended by the battery manufacturer) on the
Custom (Battery) Settings menu (see page 62).
NOTE:
This information is provided for guidance only. Variations in
battery chemistry and 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.
