Freedom Inverter/Charger Operation
loads and increase the output again when the AC load
decreases. The regulatory maximum for continuous AC loads
is 80% of the breaker rating (see “AC1 Breaker” on page 50)
that the loads are connected to. The Freedom SW senses pass-
through current going to the AC load. The difference between
the pass-through (load) and 80% of the AC1 Breaker setting
is the current that is available for charging the batteries.
For example, if the AC input of the Freedom SW is from an
AC panel with a 30-amp breaker, the AC1 Breaker setting on
the SCP 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. Should the
load current be more than 24 amps, the charger output will
reduce to 0 amp, but the Freedom SW will continue to supply
the loads. The Freedom SW will continue to pass-through
power to the loads, even if the load current exceeds the AC1
Breaker 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 is to be avoided.
NOTE: The AC1 Breaker setting can also be changed using
the Shr soft key in the SCP (see “Soft Key Navigation” on
page 29). Shr stands for shore power which refers to
incoming AC power in the mobile industry.
