The Xantrex Freedom SW 2012 is a heavy-duty 12-volt inverter/charger combining 2,000 watts of continuous true sine wave AC output with a 100-amp battery charger. Designed for marine vessels, recreational vehicles, commercial trucks and specialty vehicles, it supplies clean 120-volt AC power from the battery bank and automatically recharges the batteries when shore power or generator power becomes available.
Key Features
- Produces 2,000 watts of continuous true sine wave AC power at 40°C
- Delivers up to 4,000 watts of surge power for five seconds
- Integrated 100-amp charger for nominal 12-volt battery banks
- Generator Support Mode supplements generator output when connected loads temporarily exceed generator capacity
- Single-phase 120-volt AC input and output
- Integrated 30-amp automatic transfer relay
- Transfers between external AC and inverter operation in less than 20 milliseconds
- Xanbus-enabled for system monitoring, configuration and compatible accessory integration
- Supports compatible series-stacked installations requiring additional inverter capacity
- Includes a remote battery-temperature sensor for temperature-compensated charging
Application Compatibility
The Freedom SW 2012 is designed for demanding 12-volt electrical systems, including:
- Recreational and commercial marine vessels
- Motor yachts and cruising boats
- Recreational vehicles and motorhomes
- Heavy-duty commercial trucks
- Mobile service and work vehicles
- Specialty and emergency vehicles
- Off-grid systems using 12-volt battery banks
Its five-second 200% surge capacity helps start compatible refrigerators, pumps, air-conditioning equipment and other motor-driven loads that require substantially more power during startup than during normal operation.

Certification and Marine Installation Notice
The Freedom SW 2012 is ETL listed to CSA 107.1, UL 458 and the UL 458 Marine Supplement. Xantrex specifies marine drip shield part number 808-9004 when compliance with the UL 458 Marine Supplement is required.
The unit is identified for marine installations following applicable ABYC E-11, A-31 and A-32 requirements. It also complies with FCC Part 15 Subpart B Class B and Canadian ICES-3 Class B electromagnetic-compatibility standards.
Fitment Notice
The Freedom SW 2012 is designed exclusively for a nominal 12-volt battery bank and must not be connected to a 24-volt system. Confirm battery-bank voltage, usable battery capacity, shore-power arrangement, generator output and the startup requirements of connected AC equipment before ordering.
At full inverter output, the unit can draw well over 165 amps from the 12-volt battery system after inverter losses are considered. DC conductor size, cable length, fuse capacity, disconnect rating and battery-bank capability must therefore be selected for the inverter’s actual DC demand.
When This Product Needs Replacement
Inspect or replace the inverter/charger if it repeatedly shuts down under loads it previously supported, fails to transfer correctly between shore or generator power and inverter operation, no longer maintains its programmed charging profile or develops recurring overload, low-voltage, over-temperature or Xanbus communication faults.
Before replacing the unit, test the battery bank, DC cable voltage drop, terminal connections, incoming AC source and external circuit protection. Weak batteries, loose terminals and undersized conductors can produce symptoms similar to inverter or charger failure.
Installation Notes
Install the Freedom SW 2012 in a dry, ventilated location protected from water, excessive heat, battery gases and fuel vapours. Use properly sized marine-grade DC conductors, correctly rated battery-bank protection and an accessible DC disconnect.
Secure the approximately 60-pound unit to a structure capable of supporting its weight under vessel movement and vibration. Follow the Xantrex installation guide for mounting orientation, ventilation clearances, grounding, AC wiring and circuit protection.
Install the included remote battery-temperature sensor at the battery bank for accurate temperature-compensated charging. Use marine drip shield 808-9004 where required for marine certification.

Parts Desk Insight
The Freedom SW 2012 is well suited to substantial 12-volt systems that need strong motor-starting capacity but do not require the 3,000-watt output of the Freedom SW 3012. Both models use the same enclosure size and weight, but the 2012 provides a 2,000-watt inverter and 100-amp charger, while the 3012 provides 3,000 watts and 150 amps.
