Operating Limits for Charger Operation Operating Limits for Charger AC Frequency The charger can also be configured to accept and operate from a wide AC source frequency Operation of 40–68 Hz. Therefore, the Freedom SW-RVC can charge your batteries even when incoming By default, the maximum charger output current is the rated AC voltage is less than ideal.
Page 30
Operating Limits for Charger Operation For example, if the AC input of the Freedom SW-RVC is from an AC panel with a 30-amp breaker, the AC1 Breaker setting should be selected as 30 amps. Based on this, the charger will control the charge current so that the total current draw is equal to or less than 24 amps in this case.

Default value is Disabled. Switches between Operating and Safe modes. Desired This section contains information about all configurable settings Default value is Operating.
Configuring the Freedom SW-RVC Using Load Sense NOTE: The Slave unit continuously monitors the output of the Master unit. Why use Load Sense? If the Master unit has more than 60% of the rated load (for example, Load Sense allows the inverter to selectively power only items 1800 watts), the Slave unit will assist the Master and the two will that draw more than a certain amount of power, which can result in share the load equally.
Configuring the Freedom SW-RVC Equalization Procedure NOTE: Load Sense, by function, cannot work with clocks and timers or To start equalizing the batteries, do one of the following: devices that need power 24 hours a day. Examples of devices Apply AC voltage and ensure that the inverter/charger with timers include video recorders, coffee makers with brew transfers AC and starts charging.
