It's built for boaters and RVers who want clean, reliable power and a seamless switch between shore, generator, and battery.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Xantrex Freedom SW 3012 is a true dual-purpose power center for your boat or RV. It's both a 3000-watt pure sine wave inverter and a 150-amp multi-stage battery charger in one rugged enclosure, wired to a 12-volt battery bank and putting out clean 120-volt, 60-hertz AC. If you've ever run a laptop, a microwave, or sensitive marine electronics off a cheap modified-sine unit and heard the buzz or watched a charger act up, you already know why pure sine matters. The Freedom SW gives you household-quality power at anchor, on the hook overnight, or parked off-grid.\u003c\/p\u003e\n\u003cp\u003ePure sine wave output is the heart of this unit. It produces smooth AC that looks just like the power from your dock pedestal, so induction motors, variable-speed tools, and modern chargers all run cooler and quieter. The 3012 is rated for 3000 watts of continuous output and can surge to 6000 watts for up to five seconds, which is exactly what you need when a refrigerator compressor, a water pump, or an air conditioner kicks on. That 200 percent surge headroom means the inverter doesn't fault out the moment a big load starts.\u003c\/p\u003e\n\u003cp\u003eOn the charging side, the built-in 150-amp charger brings your 12-volt bank back to full using an advanced multi-stage profile. Whether you're running flooded, AGM, gel, or lithium batteries, you can configure the charge stages to match, so you're not cooking an expensive bank or leaving it chronically undercharged. A battery temperature sensor ships with the unit and lets the charger compensate as conditions change, which protects capacity and extends service life through hot summers and cold shoulder seasons.\u003c\/p\u003e\n\u003cp\u003eThe Freedom SW earns its name with a fast internal automatic transfer switch. When shore power or a generator is present, the unit passes that AC straight through to your loads and charges at the same time. The instant that source drops, it flips to inverter mode quickly enough to keep clocks, routers, and entertainment gear alive. There's also a generator support mode that lets the inverter add battery power alongside a smaller generator, so you can run bigger loads without upsizing your genset. It's the kind of feature that pays for itself on a busy galley circuit.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e3000 watts continuous, 6000 watts surge for five seconds\u003c\/li\u003e\n\u003cli\u003e12-volt DC input, 120-volt AC at 60 hertz output\u003c\/li\u003e\n\u003cli\u003e150-amp multi-stage charger with battery temperature compensation\u003c\/li\u003e\n\u003cli\u003eBuilt-in automatic AC transfer switch for shore and generator\u003c\/li\u003e\n\u003cli\u003eGenerator support mode to stretch a smaller genset\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThink about a typical weekend at anchor. You come off the dock with a full bank, drop the hook in a quiet cove, and the inverter quietly runs the galley, charges phones and laptops, and keeps the entertainment system alive without a generator droning in the background. In the morning you fire up the genset for an hour, and the 150-amp charger pushes real energy back into the batteries fast, so you're topped up and ready before breakfast is done. That's the cycle the Freedom SW 3012 was designed around, and it does it day after day. Installation is straightforward for anyone comfortable with DC wiring, and the unit is designed to accept an optional remote panel so you can monitor status and adjust settings from the helm or living space. Because it's built to marine and mobile standards, the Freedom SW 3012 carries ETL listing to UL 458 with the marine supplement, CSA 107.1, and FCC Part 15 Class B, and it follows ABYC guidance for onboard AC systems. That matters when you're wiring a vessel that has to pass a survey or an insurance inspection.\u003c\/p\u003e\n\u003cp\u003eAt roughly 60 pounds, this is a substantial piece of gear, and that weight reflects the heavy transformer and heat sinking that let it deliver full power hour after hour. Mount it in a cool, ventilated space close to the battery bank to keep cable runs short and voltage drop low, and you'll get years of dependable service. For a serious cruiser, a live-aboard, or a big fifth wheel, the Xantrex Freedom SW 3012 is the backbone of a quiet, capable, self-sufficient electrical system.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e3000 watts continuous pure sine wave output with 6000-watt five-second surge\u003c\/li\u003e\n  \u003cli\u003eIntegrated 150-amp multi-stage battery charger for 12-volt banks\u003c\/li\u003e\n  \u003cli\u003eBuilt-in automatic AC transfer switch keeps loads live during source changes\u003c\/li\u003e\n  \u003cli\u003eGenerator support mode blends battery power with a smaller generator\u003c\/li\u003e\n  \u003cli\u003eBattery temperature sensor included for accurate, safe charging\u003c\/li\u003e\n  \u003cli\u003eConfigurable charge profiles for flooded, AGM, gel, and lithium batteries\u003c\/li\u003e\n  \u003cli\u003eAccepts optional remote panel for helm or cabin monitoring\u003c\/li\u003e\n  \u003cli\u003eETL listed to UL 458 with marine supplement, CSA 107.1, and FCC Part 15 Class B\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Xantrex reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat is the difference between the inverter and charger functions?\u003c\/summary\u003e\n    \u003cp\u003eThe inverter turns 12-volt battery power into 120-volt AC so you can run household and marine gear off your batteries.
