Introduction
Key Features Explained
Built-in Charge Formulas For the unit to perform at the highest
level, the batteries must be charged correctly. The Freedom SW has
optimized algorithms for flooded, gel, and AGM batteries.
Battery Temperature Sensor Since battery temperature is a key
factor in correct charging, the charging formula must be adjusted
(automatically and in real time) according to the actual battery
temperature to ensure that batteries are fully charged, but not
overcharged. For this reason, a battery temperature sensor is
included with your Freedom SW and has temperature compensated
the charge formula.
Manual Equalization Over a period of time, the cells in a
flooded battery can develop uneven chemical states. This can result
in a weak (undercharged) cell which, in turn, can reduce the overall
capacity of the battery. To improve the life and performance of a
non-sealed, flooded battery, the Freedom SW’s multistage charging
cycle includes a manual equalize mode that can be used, if
recommended by the battery manufacturer.
Dead Battery Charging Another feature that the Freedom SW
includes is dead battery charging. The Freedom SW—unlike many
chargers—has the ability to recharge batteries even if the battery
voltage is very low (5 volts for Freedom SW 2012 / 3012 units and
12 volts for Freedom SW 2024 / 3024 units).
Load Management The Freedom SW has a built-in transfer relay
that connects your inverter output or AC input from the utility grid
or generator to your loads. Because the usual AC power sources
such as campground outlets or small generators often have limited
current availability, having the capability to manage your AC loads
is extremely valuable. The Freedom SW provides a number of
features to facilitate this:
The charger is power factor corrected to use AC current as
efficiently as possible. Minimizing the AC current used by the
charger means more current is available for your AC loads.
Freedom SW has a power share feature which prioritizes your
AC loads by reducing the charge current in an attempt to limit
the total input current to less than the breaker setting.
Occasionally, AC input sources have low voltage. To avoid loading
these weak sources any further, the charger automatically reduces
its AC current draw as the AC voltage approaches the minimum
acceptable level.
