Xantrex Freedom SW3012 12V 3000W Inverter/Charger

Xantrex Freedom SW3012 Inverter/Charger — 12V / 3000W

The Freedom SW3012 is a pure sine wave inverter/charger engineered for demanding mobile and off-grid applications. At 3000W continuous output with a 150A multi-stage charger, it handles everything from sensitive electronics to heavy AC loads. Its standout features include Generator Support Mode — which supplements an undersized generator when loads exceed its capacity — and a sub-10ms AC transfer time so connected equipment barely notices a power transition. Parallel and series stacking extend its capability to doubled output or 120/240V split-phase configurations.

Key Features

Pure Sine Wave Output — Clean power for sensitive electronics, variable speed motors, and modern appliances.

Generator Support Mode — Supplements generator output when AC loads exceed generator capacity, preventing overload.

<10ms AC Transfer Time — Switches to battery power in under 10 milliseconds when grid or generator power is lost — virtually undetectable to connected loads.

Parallel & Series Stacking — Parallel stacking doubles AC output in inverter mode. Series stacking enables 120/240V split-phase output (requires Stacking Cable #808-9005, AC source must be split phase).

Power Factor Corrected Multi-Stage Charger — 150A output with temperature-compensated charging for fast, efficient battery recovery across climate conditions.

Built-In Transfer Switch — Automatically transfers between inverter and incoming AC power.

Ignition Lockout — Prevents unnecessary battery drain when the alternator isn't providing power (requires remote panel).

Conformal Coated Circuit Boards — Protected for humid and marine environments.

Wide Operating Temperature — −4°F to 140°F (−20°C to 60°C).

Certifications: UL458 (with marine supplement), CSA, ABYC, FCC Class B.

Compatible with Xantrex Automatic Generator Start (Part #809-0915, sold separately).

Protection Features

Battery over-voltage and under-voltage protection • Over-temperature shutdown • Automatic overload protection • Short-circuit protection • Integrated resettable AC breakers
