Imagine powering your sensitive electronics, kitchen appliances, or power tools seamlessly during long hauls in your commercial truck, weekend getaways in your RV, or days out on the water in your marine vessel. This inverter transforms your 12V DC battery into clean 120V AC power, mimicking utility grid electricity. Unlike modified sine wave alternatives that can cause humming, overheating, or damage to devices, true sine wave output ensures smooth operation for everything from laptops and TVs to microwaves and variable-speed motors.
With a robust 1800W continuous output and a 3000W surge rating, it handles startup demands effortlessly—think refrigerators kicking on or air conditioners cycling up. At 90% efficiency, it minimizes battery drain, letting you stretch your power longer between charges.
Crafted for durability in demanding environments, this unit packs smart conveniences into a compact 13.7 x 11.8 x 3.9-inch chassis weighing just over 10 pounds. Key highlights include:
Output stays steady at 60Hz within 104-127V range, with no-load draw under 0.8A to conserve energy when idle.
Safety isn't an afterthought—it's built-in across multiple layers. Low voltage alarm triggers at 11V DC and shutdown at 10.5V to safeguard batteries from deep discharge. Over-voltage cuts off at 15.5V, while overload, over-temperature, and GFCI protections prevent fires or shocks. These features exceed basic standards, meeting UL458 for peace of mind in certified installations.
In real-world use, we've seen these safeguards shine: averting meltdowns from power-hungry tools or alerting users to failing alternators before stranding occurs.
Run coffee makers, CPAP machines, or entertainment systems off-grid without the generator noise. Its quiet fan and clean power keep inverters from interfering with inverters or audio gear.
Power fridges for driver meals, microwaves for quick heats, or even small welders during downtime. Surge capacity tackles compressor startups common in transport refrigeration.
GFCI outlets shine here, powering bait freezers, stereos, or nav electronics safely on deck. Compact size fits tight battery compartments without hogging space.
Pro tip: Pair with a 250A fuse (sold separately) and quality cables sized for your run length to optimize performance and prevent voltage drop.
Mount it securely in a ventilated spot away from heat sources, ideally near the battery bank. Hardwire DC inputs demand clean, polarity-correct connections—double-check with a multimeter. AC side plugs right into standard cords. Enable remote control for dash access, especially useful in cabs or helm stations. Always vent for cooling; ambient temps up to 104°F are fine, but avoid enclosed spaces.
For best results, calculate your total load: add continuous watts and factor 20% headroom. Test under load post-install to verify no faults.
True sine wave delivers smooth, grid-like power that prevents damage, noise, or inefficiency in sensitive devices like medical equipment, LED lights, and motors. Modified versions can cause glitches or reduced lifespan.
Yes, its 1800W continuous and 3000W surge handle typical 1000-1500W microwaves, including startup surge. Monitor total load to stay under limits.
No, it ships without cables or fuses. Use appropriately sized ones: recommend 250A fuse close to the battery for safety.
The digital display shows DC voltage. An alarm sounds at 11V, and auto-shutdown occurs at 10.5V to protect your battery.
Absolutely, pairs well with solar batteries in RVs or off-grid marine systems. Its efficiency maximizes limited solar input.
Backed by a limited two-year warranty covering defects in materials and workmanship.
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.
