INSTALLATION OPTIONS
Installation Option 1 for Freedom Marine 10, 15, 20, 25, and 30
The inverter is used in a Single Input/Single Output mode. Up to 30 amps is transferred through
the Freedom Marine unit with the charger sharing power with all of the AC loads.
In this installation example, a single 30 amp shorepower source is available and all AC loads are
supplied power through the inverter in charge/transfer mode, or by the inverter in invert mode.
The charger shares power with the AC loads and can transfer up to 30 amps. When installing a
Freedom Marine 25 or 30 model, AC Input #2 and AC Output #2 are not used and must be
capped off. The AC input power must be supplied through a 30 amp, double pole, main breaker.
In this type of a system the panel loads would normally not include any heavy loads such as
space heaters, stoves, water heaters, air conditioners, AC to DC converters, or other battery
chargers. If these types of loads are present, they should be turned OFF when inverter power is
being used to prevent overloading the inverter or rapidly discharging the battery bank. To avoid
the need for this manual form of energy management, installation options 2, 3 or 4 should be
considered.
If a generator is installed in the system, a break-before-make AC transfer switch is used to select
between shorepower or generator power. The transfer switch AC output is then routed to the
input of the inverter/ charger.
