The Xantrex Freedom SW3024 24V Inverter/Charger is a powerful, flexible power solution built for off-grid, marine, and mobile applications. This B-Stock unit (Scratch and Dent) delivers clean, utility-grade power with smart charging and scalable options to match demanding loads.
-
Inverter power: 3000 W continuous (40°C) output with 6000 W surge capability for heavy loads and short bursts.
-
Pure sine wave output: Ensures clean, stable power suitable for sensitive electronics and modern appliances.
-
Stacking flexibility: Parallel (two 24V units) to double inverter power and series stacking for 240 V applications.
-
Automatic transfer switch: Seamless (< 20 ms) transfer between inverter power and incoming AC to protect critical loads.
-
Dual input / dual output AC interface: 3000 W model with flexible connections; compatible with System Control Panel and Automatic Generator Start accessories.
-
Smart charging: Three-stage charging with temperature compensation; remote battery sensor included; efficiency > 85% and PF around 0.95 during max charging.
-
Ignition lockout: Helps prevent battery drain when the alternator isn’t supplying power.
-
Environment and reliability: Wide operating temperature range; conformal-coated circuit boards for humid environments; rugged construction for challenging installations.
-
Safety and compliance: Meets CSA, UL458 (marine supplement), ABYC, and FCC Part 15 Class B requirements.
-
Electrical and charging specs: 75 A maximum charging current; charger output 24 Vdc (range 12–32 Vdc); inverter input 20–32 Vdc; AC input 120 Vac; 60 Hz ± 0.2 Hz; output 120 Vac.
-
Battery compatibility: Compatible with Flooded, Gel, and AGM battery types; dead battery charge > 12 Vdc.
With the SW3024, you gain a reliable, utility-grade power backbone for off-grid, marine, and mobile deployments. The parallel/series stacking enables growth from a single 3000 W inverter to higher power levels or 240 V loads, while the automatic transfer switch keeps critical appliances powered with seamless handoff. Smart charging preserves battery health and maximizes efficiency with a remote sensor and temperature compensation. Built to perform in harsh environments and backed by broad safety standards, this unit is well-suited for demanding setups—now available as a B-Stock option with minor cosmetic blemishes but full electrical capability.
