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
