Battery Charger Functions
When AC power is available, the Freedom XC PRO can operate
as a 12-volt 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 XC PRO 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
).
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.
Battery Types
The Freedom XC PRO Inverter/Charger charges flooded (or wet)
lead-acid, Gel, AGM (absorbed glass mat), custom, and lithium
iron phosphate (LFP) batteries.
n
Flooded (or wet) batteries have removable battery caps for
refilling with distilled water and testing the electrolyte.
NOTE
: Add distilled water in each cell until battery acid
reaches the level specified by the battery manufacturer. This
helps purge excessive gas from cells. Do not overfill. For a
battery without cell caps, carefully follow the battery
manufacturer’s recharging instructions.
n
Gel batteries have the electrolyte in the form of a gel rather
than a liquid and do not require topping up. Gel batteries are
sealed and the battery caps are not removable.
n
AGM (Absorbed Glass Mat) batteries are similar to gel
batteries except that the electrolyte is absorbed into a
fiberglass matting.
n
Custom battery is configured by the dealer, factory, or
service center for battery types other than those listed
above.
n
Lithium iron phosphate (LFP) must only be selected with a
lithium iron phosphate battery module with a certified Battery
Management System (BMS).
