Imagine powering your entire RV setup, marine electronics, or remote worksite without worrying about blackouts or weak grid connections. This robust 12V 3000W unit steps in seamlessly, delivering pure sine wave power that mimics utility-grade electricity. Sensitive gadgets like laptops, medical devices, and high-end audio systems run smoothly without glitches or damage. What sets it apart? Its smart design handles heavy loads while prioritizing battery health, making it a go-to for off-grid enthusiasts who demand performance without compromise.
In real-world scenarios, users rave about its quick transfer switch—under 10 milliseconds—keeping fridges humming and lights steady during generator hiccups or shore power drops. Whether you're boondocking in the desert or navigating choppy waters, this inverter/charger adapts to your lifestyle, charging batteries efficiently even from deeply discharged states.
Crafted with marine-grade conformal coatings, it thrives in humid, salty air or dusty job sites. The wide temperature range from -4°F to 140°F ensures operation in extreme conditions, from arctic outings to scorching summers. Dual AC inputs and outputs on the 3000W model give flexibility for complex setups, like integrating multiple power sources.
Compatibility shines with automatic generator starts, letting you kick off backup power remotely for unattended systems.
Need more juice? Parallel stacking doubles output to 6000W for massive loads like air conditioners or welders. For split-phase 120/240V needs—think home-like setups on a boat or truck—series stacking delivers balanced power. Just ensure your AC source matches, and you're set for expansion that grows with your ambitions.
This versatility shines in commercial fleets, where one unit starts small but scales as routes expand, or in emergency response vehicles needing redundant power layers.
Safety isn't an afterthought. Over-voltage, under-voltage, overload, and short-circuit protections kick in instantly, with resettable breakers saving downtime. Over-temperature shutdowns protect internals during prolonged heavy use, while the rugged build meets stringent UL458 marine, ABYC, and FCC standards—certified for vibration-heavy mobile life.
"In over a decade of testing similar inverters, these protections have prevented more headaches than any other feature—especially in generator-supplement mode during peak summer loads."
From recreational RVers chilling off-grid for weeks to contractors powering tools at remote sites, its configurability fits niche needs. Marine pros use it for stable nav systems and fish finders; military-grade durability handles tactical ops. Generator support mode is a game-changer, boosting smaller gensets to handle surges without stalling.
Pair with deep-cycle batteries sized to 400-600Ah for optimal runtime. Monitor via optional remotes for tweaks like custom charge profiles, ensuring years of trouble-free service even as a remanufactured unit—often performing like new after expert refurbishing.
Remanufactured means rigorously tested components, fresh firmware, and a fresh one-year warranty—delivering factory-fresh reliability at a fraction of new costs. It's eco-friendly too, reducing waste while giving you proven tech that's outlasted countless adventures.
Pure sine wave provides clean, stable power identical to grid electricity, preventing overheating, noise, or failure in sensitive devices like TVs, computers, and medical equipment—unlike cheaper modified waves.
Yes, its multi-stage, temperature-compensated charger works with lithium, AGM, and flooded batteries. Customize profiles via advanced settings for optimal performance and safety.
It supplements a running generator when loads exceed its rating, seamlessly blending inverter power to avoid overloads—perfect for undersized gensets during high-demand periods.
Absolutely—UL458 marine supplement, ABYC compliance, conformal coatings, and wide temp range make it ideal for boats, RVs, and harsh mobile environments.
Parallel doubles power to 6000W; series creates 120/240V split-phase. Expand your system affordably as needs grow.
Less than 10 milliseconds—your loads barely notice the switch from grid/generator to battery power.
Yes, it recovers and charges batteries drained to very low voltages, with under-voltage protection to safeguard the system.
Freedom SW3012 12V 3000W Inverter/Charger - 1-Year Warranty *Remanufactured
Powerful. Configurable. Versatile.
The Freedom SW series represents highly sophisticated and advanced inverter/ chargers available in 3000 W with 150 A charger and 2000 W with 100 A charger models.
The second-generation 3000-watt model has been completely redesigned to include many of the same great features found in its high-power counterpart. A key feature enhancement is 'Generator Support Mode' which enables the Freedom SW to supplement a generator when AC loads exceed the generator's capacity. The new generation models also feature improved AC transfer/AC input detection time, providing the ability to transfer AC loads to batteries in less than 10 milliseconds when the incoming grid or generator power is lost. Connected loads are almost unable to feel the power transition due to this quick transfer time. Both models are approved for UL458 with marine supplement, CSA, ABYC, and FCC, Class B requirements.
Parallel & Series Stacking
Parallel stacking enables the Freedom SW inverter/chargers to double the AC output in inverter mode. Series stacking enables the Freedom SW inverter/chargers to generate 120/240 V split phase output2.
2 AC source must be split phase, requires Stacking Cable (part# 808-9005)
Designed for a variety of mobile applications such as commercial, emergency, and recreational vehicles, marine vessels, construction, and military equipment.
