SW Series Inverters

The Trace SW-series, the world's best and most advanced inverter.

Some inverters simply cannot supply power clean enough for equipment like clocks, timers, laser printers, photocopiers, bread makers and pellet stoves. And modified sine wave inverters sometimes cause "noise" on radios or tv sets.


  • New design makes it easy to use.
    • With separate "use" and "setup" menus, new backlit display, improved wiring access and greater generator compatibility.
  • Advanced engineering boosts efficiency.
    • The SW is over 90% efficient through most of its load range, peaking at 96% efficiency.
  • There's negligible idle current.
    • Smart features make it more reliable.
  • New "soft start" system allows inverter to run heavier loads with improved reliability.
    • Intelligence eliminates guesswork.
  • "Brainy" Trace SW inverters can be programmed to perform a multitude of tasks like automatic generator start and stop, automatic load sensing, and generator support.
    • Protective circuitry guards against downtime.
  • Including over-current, short circuit, over temperature, low battery and high battery conditions.
    • Feed-back ability makes you a power broker.
  • When connected to a renewable energy system, The SW can feed excess energy back to the utility grid.
    • Charger keeps your batteries happy.
  • All Trace SW inverters include a built-in, fully automatic, three-stage battery charger. It's designed for maximum charging while using minimum generator time and fuel.
    • Outputs match any need.
  • The SW comes in 2.5 kw /12 volt output to 5.5 kw/48 volt models.
    • Most popular models: 4 kw, 24 and 48 volt inverters.
  • Stacking offers power to spare.
    • Stack the SW in series for 120/240 VAC output and increased total capacity. With a surge rating 2.5 times greater than their continuous power rating, there is almost nothing that will not start and run on one (or two) of these inverters. (Export models are not stackable, including 230 VAC 50 Hz, 105 VAC 50 Hz 105 VAC 60 Hz.)
