    you should add distilled water. Follow the battery manufacturer’s recommendations for maintenance. • Never allow the tops of the battery plates to be exposed to air. This will contaminate the battery cells. When neces- sary, add distilled water to the battery. •...

  • Page 13: Battery Discharge/Charge Cycling

    Battery Discharge/Charge Cycling Deep-cycle batteries can be discharged about 80% of capacity before damage occurs. Shallow cycling will result in a longer battery life. A 50% discharge cycle is generally considered to be a good compromise between long battery life and battery bank size.

  • Page 55: Operation

    OVERLOAD / AGM LOW BATTERY / GEL2 CHARGE / GEL1 INVERT / WET The Freedom Inverter/Charger performs three distinct func- tions: 1. DC to AC power inverting. This provides 120-volt AC power from deep cycle DC batteries. 2. Automatic transfer switching between inverter power and incoming AC power.

  • Page 56: Selecting The Battery Type

    Selecting the Battery Type The selected battery type tells the Freedom Inverter/Charter what voltage settings to use. The unit remembers which type of battery you select. It will use this type each time you con- nect input power. 1. If the inverter is on, i.e., the INVERT LED is a steady green or blinking, press the INVERT button for 5 seconds.

    Optional Equalizing Charge Stage 4 - Equalizing Charge (Optional) Warning Do not equalize gel cell or AGM batteries. The equalizing charge is a controlled, over-charge cycle. During the cycle, the battery voltage will increase to the equalizing voltage. This will cause the battery bank to gas profusely.
  • Page 69 To equalize the batteries Equalizing is recommended only for wet cell batteries. Do not equalize gel cell or AGM batteries. 1. Do not equalize the batteries until they have completed the full 3-stage charge cycle. 2. Remove all loads from the DC system. Some DC loads may not tolerate the high charge voltage.

  • Page 70: Temperature Sensitive Charging (Tsc)

    To cancel equalizing • Interrupt the AC power to the charger at any time during the cycle. Temperature Sensitive Charging (TSC) When the battery temperature sensor is connected to the unit and to the batteries, the charge voltage is controlled based on battery temperature.
