Battery Charging Reference
This section describes the multistage charging algorithm (formula)
of the Freedom SW 230V.
Battery Types
Freedom SW 230V
charges 24-volt flooded (or wet) lead-acid, Gel,
AGM (absorbed glass mat), and custom batteries.
•
Flooded (or wet)
batteries have removable battery caps for
refilling with distilled water and testing the electrolyte.
•
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.
•
AGM (Absorbed Glass Mat)
batteries are similar to gel
batteries except that the electrolyte is absorbed into a fiberglass
matting.
•
Custom
battery is configured by the dealer, factory, or service
center for battery types other than those listed above.
Charge Algorithm Stages
Three-Stage charging
If three-stage charging is enabled, the Freedom SW 230V will
charge batteries in a sequence known as three-stage charging.
Whenever qualified AC power is present at the inverter’s input, it
passes power through to the connected load and begins charging the
batteries. The charging voltage delivered to the battery depends on
the battery’s:
•
type setting
•
temperature (by switch setting or battery temperature sensor)
•
state of charge
RISK OF BATTERY DAMAGE
Since the Freedom SW 230V can only select one battery type setting for
all batteries connected to its bank,
do not mix
battery types. All connected
batteries should either be: Flooded (or wet)
or
Gel
or
AGM
or
Custom.
Failure to follow these instructions can damage the unit and/or damage
other equipment.
