Rated for 1800 watts continuous and 3600 watts surge, it's a hardwire-only workhorse built for real boat and RV power systems, with thermal protection and remote on\/off capability built in.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Go Power GP-SSW-1800-12 is a smart sine wave inverter that turns your 12-volt house bank into clean 120-volt AC power. It's rated for 1800 watts continuous with a 3600-watt surge, so it'll run the AC gear you actually use at anchor, a microwave, a coffee maker, a laptop and charger, a small power tool, without choking on the startup spike when a motor or compressor kicks in.\u003c\/p\u003e\n\u003cp\u003eSmart sine wave output is the part that matters here. This isn't a cheap modified-square-wave unit that buzzes through your speakers and cooks sensitive electronics. The 120-volt AC it puts out follows a clean sine curve, close to what you get from shore power or a generator, so your TV, battery chargers, and anything with a switching power supply run cool and quiet. If you've ever tried to run a laptop brick off a bargain inverter and watched it get hot, you know why that matters.\u003c\/p\u003e\n\u003cp\u003eThis is a hardwire-only inverter. There are no receptacles on the case. You wire it straight into an AC subpanel, which is exactly how you want a permanent boat or RV install to look, no cords hanging off the front, no adapters. Plan on a small AC distribution panel with its own breakers downstream of the inverter. A lot of boaters add a subpanel with GFCI breakers so the galley and head outlets are protected. It's a bit more work up front than a plug-in unit, but the result is a clean, safe system you can actually trust offshore.\u003c\/p\u003e\n\u003cp\u003eOn the DC side, respect the numbers. At full 1800-watt load this inverter pulls right around 100 amps from the battery bank. That's real current. You'll want heavy DC cable, 4\/0 AWG is the common call, kept as short as you reasonably can, with a properly sized fuse or breaker right at the battery. Long, undersized runs drop voltage and the inverter will complain or shut down before it ever reaches full output. Size the bank to match, too. A 400-amp-hour AGM or lithium bank with a decent charger keeps you from flattening your batteries in twenty minutes of microwave time.\u003c\/p\u003e\n\u003cp\u003eHeat is the other thing to think about. At 88 percent efficiency, roughly 200 watts turns into heat at full tilt, and the built-in thermal protection will derate or shut the unit down if it can't breathe. Don't bury it in a sealed lazarette. Mount it on a metal bulkhead if you can, give it airflow, and it'll run all day. Tucked under a V-berth or in a vented equipment locker on a 30-to-35-foot boat, it fits and stays cool. On a tight powerboat with a cramped battery box, measure first, the 16-1\/2 by 9 by 4.1 inch case is compact but it still needs room around it.\u003c\/p\u003e\n\u003cp\u003eThe inverter is remote on\/off capable, so you don't have to crawl back to the unit every time you want AC power. Wire in a remote switch at the helm or in the living space and flip it on from where you actually are. Keep the remote cable runs clean and away from your antenna leads. Between thermal protection, short-circuit, and overload safeguards, the GP-SSW-1800-12 shuts itself down before a fault becomes a bigger problem, and it's backed by a 2-year Go Power warranty.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Cruisers and RVers who want honest, permanent AC power without dragging a generator along. It's a workhorse for running galley appliances, charging tool batteries, or keeping the essentials going off the grid. It's not the pick if you just want to plug one phone charger in now and then, a small plug-in inverter does that for a lot less. But if you're building out a real house system and you want clean power you can hardwire once and forget about, this one earns its spot.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e1800 watts continuous, 3600 watts surge: runs a microwave, coffee maker, or power tool and still has headroom for the startup spike\u003c\/li\u003e\n  \u003cli\u003eSmart sine wave output: clean 120V AC that won't buzz through audio or overheat sensitive gear like laptops, TVs, and battery chargers\u003c\/li\u003e\n  \u003cli\u003e100 amps continuous DC draw at full load: size your 4\/0 AWG cabling, fusing, and battery bank around it for stable output\u003c\/li\u003e\n  \u003cli\u003eUp to 88 percent efficiency: less of your battery power lost as heat, more of it reaching your outlets\u003c\/li\u003e\n  \u003cli\u003eHardwire-only connection: wires straight into an AC subpanel for a clean, permanent install with no dangling cords\u003c\/li\u003e\n  \u003cli\u003eRemote on\/off capable: add a remote switch at the helm or living space so you're not crawling into the lazarette to power up\u003c\/li\u003e\n  \u003cli\u003eThermal protection plus short-circuit and overload safeguards: shuts down before a fault turns into a real problem\u003c\/li\u003e\n  \u003cli\u003eCompact 16-1\/2 x 9 x 4.1 inch case: tucks under a V-berth or into a vented equipment locker\u003c\/li\u003e\n  \u003cli\u003eBacked by a 2-year Go Power warranty\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 Go Power 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\u003eIs this a pure sine wave inverter?\u003c\/summary\u003e\n    \u003cp\u003eYes.
