Xantrex Technologies 815-3012-11 Freedom SW 3012 3000W 12V True Sine Wave Inverter/Charger

The Xantrex Freedom SW 3012 is a 3000-watt, 12-volt true sine wave inverter/charger built for demanding mobile power applications. Delivering clean, stable AC power and a built-in 150-amp multi-stage battery charger, it is engineered for RV, marine, commercial vehicle, emergency services, construction, and military use.

The Freedom SW 3012 features a built-in transfer switch that automatically switches between inverter power and incoming AC power in less than 10 milliseconds—so fast that connected loads barely register the transition. The unit's Generator Support Mode allows it to supplement a generator when AC loads exceed the generator's rated capacity, maximizing the output of smaller gensets.

Key Features:

• 3000W continuous output at 40°C with 200% (2x) power surge for up to 5 seconds to support motor start loads
• True sine wave output at 120V / 60 Hz — safe for sensitive electronics
• 150-amp power factor-corrected multi-stage charger for fast, efficient battery charging
• Compatible battery types: LiFePO4, Flooded, Gel, and AGM
• Ability to charge batteries drained to extremely low voltage
• Parallel and series stackable — parallel doubles AC output in inverter mode; series enables 120/240V split-phase output (requires Stacking Cable 808-9005)
• Xanbus Enabled — works with the Freedom SW ComBox accessory (809-0918) for remote monitoring, data logging, and system control via smartphone or tablet
• Ignition lockout feature to minimize unnecessary battery drain when alternator is not active
• Wide operating temperature range: -4°F to 140°F (-20°C to 60°C)
• Conformal coated circuit boards for protection in humid environments
• Dual AC input / dual AC output interface
• Compatible with Xantrex Automatic Generator Start accessory (Part# 809-0915)
• Battery over-voltage and under-voltage protection
• Certifications: UL458 with marine supplement, CSA, ABYC, and FCC Class B
