Operating The Freedom SW 3000
Operating Limits for Charger Operation
The maximum output current for the Freedom SW 3000 is 150 amps. You
can reduce the total output if you change the “Max Chg Rate” setting on the
Freedom SW 3000 Advanced Menu or the maximum “Power Share”setting
on the Freedom SW 3000 Basic Menu.
The charger can operate over an AC input range of 90–135 volts AC. This
is the default setting and can be adjusted to 85–145 volts AC as a maximum
range and to 110–120 volts AC as a minimum range.This wide range allows
the Freedom SW 3000 to charge your batteries even when incoming AC
voltage is less than ideal.
Power Share The Freedom SW 3000 charger uses AC input line 1 to
charge the batteries. The Freedom SW 3000 charger shares incoming 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 loads and increase the
output again when the AC load decreases. The regulatory maximum for
continuous AC loads is 80% of the breaker rating that the loads are
connected to.
The Freedom SW 3000 senses pass-through current going to the AC load.
The difference between the pass-through (load) and 80% of the Power
Share setting is the current that is available for charging the batteries.
For example, if the AC input of the Freedom SW 3000 is from an AC panel
with a 30A breaker, the Power Share setting on the SCP should be selected
as 30A. Based on this, the charger will control the charge current so that the
total current draw is equal to or less than 24A in this case. Should the load
current be more than about 24A, the charger output will reduce to 0A, but
the Freedom SW 3000 will continue to supply the loads. The Freedom SW
3000 will continue to pass-through power to the loads, even if the load
current exceeds the Power Share setting. In this case, it will be up to the
user to remove/disconnect loads if tripping the AC input breaker supplying
the Freedom SW 3000 is to be avoided.
