Samlex America

Run Household-Quality AC Power From Your Battery Bank

Samlex America pure sine wave inverters turn 12V or 24V DC battery power into clean 115V or 120V AC that behaves like shore power. For more than three decades, Samlex has built conversion equipment that marine operators, RV owners, and commercial fleets trust when the grid is out of reach.

Plug in the appliances you use—refrigerators, microwaves, tools, laptops, and medical devices—and keep them running without the heat, buzz, or shutdowns cheaper modified-sine inverters introduce. GMI Energy sells the Samlex models most common for boats, rigs, and work vehicles, so you can size the system once and rely on it season after season.

Protect Sensitive Gear With True Sine Wave Output

Pure sine wave power matches utility electricity. Motors start cleaner, chargers stay cooler, and audio, video, and control electronics stay free of interference. That difference shows up every time you power a device that expects real household current.

• Run CPAP machines, TVs, laptops, and variable-speed tools without flicker, noise, or unexpected cutouts
• Keep inductive loads such as pumps, compressors, and microwaves quieter and cooler under load
• Reduce electrical interference so radios, instruments, and entertainment systems stay clear
• Draw less idle current so your battery bank lasts longer between charges

Match the Inverter to the Job: PST or NTX

Choose the Samlex line that fits how—and how hard—you use power on the water, on the road, or on the job.

The PST Series is Samlex’s flagship. Heavy-duty construction, a wide operating temperature range, and hardwire options on select models make PST the choice for continuous-duty service and emergency backup. Available in 12V and 24V from 600W to 3000W, PST units carry a three-year limited warranty in the U.S. and Canada and are built for long hours at rated output.

The NTX Series delivers the same clean sine wave in a compact, lighter chassis that slips into tight compartments. Hypersurge™ technology holds surge longer so motor loads start without nuisance trips. Models from 1000W to 3000W include the NTX-RC remote for on/off control and status at a glance, and the 3000W unit adds a locking 30-amp outlet so you can use full rated power without hardwiring.

Engineered for Boats, Rigs, and Work Vehicles

Salt air, vibration, and long idle hours punish cheap inverters. Samlex designs for those conditions with temperature-controlled cooling, protection against low voltage, overload, over-temperature, and short circuit, plus ETL safety listing and FCC compliance that helps keep nearby electronics quiet.

Install a 12V inverter on a typical RV or small-boat bank, or step up to 24V when you need higher wattage with lower current and slimmer cable. Either way, you get AC power that feels like home while you stay mobile—and a conversion platform that works with the batteries and charging gear already in your GMI Energy system.
