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
230V has optimized algorithms for 24-volt 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 230V 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 230V’s multi-stage
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
230V includes is dead battery charging. The Freedom SW 230V—
unlike many chargers—has the ability to recharge batteries even if
the battery voltage is very low, i.e., as low as 12 volts.
Load Management The Freedom SW 230V 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 230V
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 230V has a power share feature which prioritizes
your AC loads by reducing the charge current and maintaining
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.
