Imagine powering your sensitive gadgets, kitchen appliances, or even power tools far from the grid—without a hitch. This inverter delivers clean, pure sine wave AC power that mimics utility electricity, ensuring smooth operation for everything from laptops and medical devices to coffee makers and microwaves. Unlike modified sine wave alternatives, it prevents buzzing, overheating, or premature wear on your equipment, making it a smart choice for off-grid lifestyles.
Designed for rugged environments, its compact footprint slips easily into tight spaces in RVs, boats, or truck cabs. Whether you're boondocking in the wilderness, cruising coastal waters, or hauling loads cross-country, it converts your 12V DC battery power into stable 240V AC output, keeping your setup humming efficiently at up to 90% efficiency.
Safety isn't an afterthought—it's built-in. Low voltage alarm and shutdown (at 11V and 10.5V DC) protect your battery from deep discharge. Over-voltage cutoff (at 15.5V DC) guards against spikes, while overload, over-temperature, and short-circuit protections shut things down before damage occurs. GFCI outlets add an extra layer against shocks, ideal for wet environments like boats or RVs during rain.
These features mean less worry about unexpected failures, letting you focus on the adventure. In real-world tests by off-road enthusiasts, units like this handle surge demands—like fridge startups or tool kicks—without flinching, surging up to 2000W to get the job done.
Installation is straightforward for DIYers: hardwire to your battery with appropriately sized cables (we recommend fusing at 150A for safety). Mount it securely in a ventilated spot, connect the heavy-duty terminals, and you're ready. The included digital readout helps troubleshoot on the fly, showing voltage, power draw, or error codes if needed.
Pro tip: Pair it with a deep-cycle battery and solar panels for extended off-grid stays. It's optimized for 12V systems, drawing under 0.6A at no load, so it sips power when idle. Operating temps from 32°F to 104°F ensure it performs in everything from desert heat to chilly mornings.
RV Enthusiasts: Run your AC unit, microwave, or CPAP machine silently—no generator noise ruining the campfire vibe.
Marine Users: Powers fish finders, radios, and small appliances reliably, with corrosion-resistant design for salty air.
Truckers: Keeps fridges, TVs, and chargers going during long hauls, with remote control integrating seamlessly into your dash.
At just 7.2 lbs and dimensions of 3.5" H x 8.7" W x 13.4" L, it's lightweight and portable enough for quick swaps between vehicles.

True sine wave provides smooth, grid-like power that's safe for sensitive electronics like TVs, computers, and medical devices. Modified sine wave can cause humming, inefficiency, or damage over time.
Yes, with 2000W peak capacity, it easily manages surges from motors in fridges, microwaves, or tools—far beyond its 900W continuous rating.
Absolutely—its compact size, GFCI outlets, and protections against moisture, vibration, and temperature swings make it perfect for boats and campers.
It works with 12V deep-cycle or AGM batteries. The built-in low-voltage alarm (11V) and shutdown (10.5V) prevent over-discharge; monitor via the digital display.
No, for custom installs, source cables rated for high amps and add a 150A fuse close to the battery for safety.
It comes with a limited two-year warranty, covering defects in materials and workmanship under normal use.
Yes, connect via a charge controller to recharge your battery during the day, creating a full off-grid power system.
The compact, easy-to-use and easy-to-install design of the PROwatt SW Series makes it ideal for use in commercial truck, RV and marine applications. With True Sine-Wave output, the PROwatt SW Series can provide power for all types of electrical loads including, variable speed power tools, advanced electrical appliances, microwaves and much more. The PROwatt SW provides household AC power anywhere.
