Description

 

 

Batt Type

Sets the system battery chemistry and type: Flooded, AGM, Gel, and Custom.

 

Selecting Custom displays the Custom Settings item, which allows you to

 

adjust the settings for each charging stage.

 

 

Custom

Displays the Custom Battery Settings menu, where you can adjust

Settings

settings specific to your battery type and installation. It is only displayed if

 

Custom is selected as the Batt Type.

 

 

Batt

Selects the system battery capacity in amp hours. Setting the battery capacity to

Capacity

0 resets the charging current to its default values. Zero Ah battery capacity

 

implies there is no absorption exit current criteria and absorption only exits

 

when the absorption timer (default 3hrs, range 1min-8hr) expires.

 

 

Max Chg

Sets the percentage of the maximum DC output current that is available to the

Rate

charger. The maximum DC output current for different models is:

 

Freedom SW 2012 —100 ADC

 

Freedom SW 3012 —150 ADC

 

Freedom SW 2024 —50 ADC

 

Freedom SW 3024 —75 ADC

 

If multiple Freedom SWs are charging the same battery bank, set each

 

inverter's Max Chg Rate to 1/n of the desired charge rate (where n is the

 

number of inverter/chargers).

 

 

Charge

Sets the charging method: 3Stage (bulk, absorption, float) or 2StgNoFloat

Cycle

(bulk, absorption, no float).

 

 

ReCharge

Sets the recharging volts to tell the charger to initiate charging when the battery

Volts

drains past the value setting.

 

 

Auto

Enables or disables automatic charging. When there are two or more power

ReCharge

sources for charging batteries, Auto ReCharge can be disabled to allow

 

manual charging of batteries.

Absorb

Sets the maximum time spent in the absorption stage, before transitioning to float

Time

or no float.

 

NOTE: The Absorb Time setting resets to its default value of 180 minutes when the

 

Battery Type is changed except when changing to Custom Settings. In Custom

 

Settings, the Absorb Time setting will not reset to its default value.

 

 

Default

Selects the battery temperature charging compensation if a battery temperature

Batt Temp

sensor is not installed. In the absence of a battery temperature sensor, the

 

charger uses one of three settings: Cold (5 °C/41 °F), Warm (25 °C/77 °F), or

 

Hot (40 °C/104 °F).

 

 

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 50).

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.
