Power your off-grid lifestyle and mobile operations with the Xantrex Freedom SW2012 12V 2000W Inverter/Charger — a redesigned second-generation inverter that combines serious power with smart features. The 2000 W model delivers dependable pure sine wave power and a 100 A charger, engineered for demanding environments from recreational vehicles to marine vessels and emergency fleets.
Key strengths at a glance
-
Pure sine wave output ensures safe, noise-free operation for sensitive electronics and appliances.
-
2000 W continuous power with a 4000 W surge for quick bursts; ideal for heavy startup loads.
-
100 A multi-stage charger with temperature compensation for fast, efficient charging across climates.
-
Generator Support Mode to supplement a generator when AC loads exceed capacity, keeping critical devices online.
-
Ultra-fast AC transfer in under 10 milliseconds, so connected loads barely notice the switch from grid/generator to battery power.
-
Parallel and Series stacking options (requires stacking cable) to double AC output in inverter mode or generate 120/240 V split-phase power for more demanding setups.
-
Built-in transfer switch automatically switches between inverter power and incoming AC power for seamless operation.
-
Advanced charging technology with power factor correction and multi-stage charging for optimum battery health and efficiency.
-
Temperature-tolerant design with a wide operating range (-4°F to 140°F / -20°C to 60°C) and conformal-coated circuit boards for humid environments.
-
Ignition lockout to prevent unnecessary battery drain when the alternator isn’t providing power (works with the optional remote panel).
-
Approved and robust UL458 with marine supplement, CSA, ABYC and FCC Class B compliance for reliable performance in diverse applications.
-
Remote system integration compatible with Xantrex Automatic Generator Start (Part# 809-0915) for hands-off power management.
-
Designed for a wide range of mobile applications — including commercial, emergency and recreational vehicles, marine vessels, construction sites and military equipment.
What makes the Freedom SW2012 stand out
