Freedom Inverter/Charger Operation
• DC cabling is no longer than the recommended length.
Refer to the Freedom SW Sine Wave Inverter/Chargers
Installation Guide for this information.
• AC wiring is of recommended size. Refer to the Freedom
SW Sine Wave Inverter/Chargers Installation Guide for
this information.
• Battery is of sufficient capacity and is fully charged.
NOTE: Many 24 V inverter battery banks have a capacity
between 200–400 Ah and 12 V inverter battery banks have a
capacity between 400–800 Ah. Refer to the Freedom SW Sine
Wave Inverter/Chargers Installation Guide for sizing
requirements.
Operating Limits for Charger Operation
By default, the maximum charger output current is the rated
charger output current for the particular model. Using the
SCP, you can reduce the total output if you change the
maximum charge rate (Max Chg Rate) on the Freedom SW
Basic Settings menu or Inverter Settings menu under
Advanced Settings.
The charger can operate within an AC input range of 95–135
volts. The default settings are 95 and 135, which are the ACIn
Lo Volt and ACIn Hi Volt respectively. The ACIn Lo
Volt setting has a range of 78–115 volts and the ACIn Hi
Volt setting has between 125–140 volts.
AC Frequency The charger can also be configured to
accept and operate from a wide AC source frequency of 40–
68 Hz. Therefore, the Freedom SW can charge your batteries
even when incoming AC voltage is less than ideal. The
default settings are 45 and 55 Hz, which are the ACIn Lo
Freq and ACIn Hi Freq settings respectively.
Power sharing The Freedom SW charger uses incoming
AC or shore power (see following note) to charge the
batteries. The charger shares incoming AC power with AC
loads on Line 1 only. The AC loads have priority, which
means that the charger will reduce its output with large AC
