Advance technology boosts power inverter capabilities

This is Mike Sokol from and the No~Shock~Zone. I’ve asked for a sample TruePower Plus inverter that’s introduced in the press release below. Once it’s in my hands I’ll test it and confirm how well it works. Watch for my review of this product in a special column soon.  

TruePower Plus inverters have been taken to the next level using the latest in digitally controlled and software-based power conversion technology. They provide the convenience of clean household power for electric grills, entertainment systems, refrigeration and more. TruePower Plus not only converts 12VDC to 120VAC household power but will seamlessly pass through AC shore power with its built-in 30A transfer switch. “With greater demands being put on RV power systems, there was a definite need for an inverter with advanced technology,” said Reese Bischoff, RV Sales Manager.

The inverters include an intuitive dual color user interface consisting of an LCD display, AC power output, and DC input power gauges. LED indicators display power input type and service notifications. When the system is operating normally, the entire display screen illuminates blue and green. If there is a system error, the LCD display and gauges will turn red.

In addition, the LCD display will provide a full text fault message versus confusing error codes. This innovative design takes the stress and mystery out of using an inverter for RVs. “We put a tremendous amount of research and development into the TruePower Plus design,” said Bischoff. “Our top priority was to align the features with the way RVers use inverters.”

Installation time is significantly reduced with innovative AC cable strain reliefs and easy access, color-coded AC terminal blocks. This eliminates punching holes and using conduit-style strain reliefs and ring terminals for AC power connections.

The TruePower Plus inverters are designed with x2 surge capability for demanding loads, convenient GFCI protected outlets and a USB charging port. Shock resistant and internal conformal coated electronics ensure protection in harsh environments.

On Board Solutions TruePower Plus inverters range in price from $299.99 to $589.99, and are available in both Modified Sine Wave (MS) 1200, 1500 and 2000 watts and Pure Sine Wave (PS) models in 1,000 and 2,000 watt models. Learn more here.



11 Thoughts to “Advance technology boosts power inverter capabilities”

    Should a power inverter cooling fan run all the time? Ours runs even when I think I have everything turned off and unplugged from shore power

    1. Mike Sokol

      It really shouldn’t. Most modern electronics with a cooling fan have some sort of thermal sensor that only turns on the fan when needed. Have you looked in the owner’s manual for your inverter to see if that’s a feature?

      1. Ronald cardwell

        Thanks I’ll have to look it up after I find it get the numbers. I love reading all of the information you give us Ronnie

    TruePower Plus not only converts 12VDC to 110VAC . Why 110 volts AC. I would have thought 120 Volts AC would be more efficient ?


    1. Mike Sokol

      That’s very likely just a typo in the press release. Depending on how old you are, you tend to call it 110, 115 or 120 volts. That’s because those were the actual voltages of the US power grid in the past and present. The “official” voltage according to NFPA-70 is currently 120-volts. Of course this is one of the things I’ll measure when TruePower sends me a demo unit to test, but I’m sure it’s actually 120-volts, not 110 volts. Good catch!

    These inverters don’t “boost inverter capabilities” in the sense of actual power conversion, but they do have better instrumentation for “meter watchers” like me.

    I picked up a 2000/4000 pure sine inverter for $60, and added 12V and 120V V/A/W LCD meters both sides for $3 each. $66 with clearer displays than these $600 units… But not everyone here wants to save money over slightly more plugNplay, so use your preferences.

    I think I can get 120V/30A auto-transfer (genny) switches for around $10, but I don’t use one on the inverter since I deliberately go on/off inverter…

    Whats the difference between Modified Sine Wave and Pure Sine Wave . And why would we need one or the other?

    1. Wolfe

      To quote myself, back when I was still writing for RVT:

      Shortish answer: MSW is actually a choppy staircase wave, while pure sine should be smooth like wall power. The choppiness makes harmonics that can harm efficiency, and may interfere with or overheat the switching power supplies in sensitive electronics.

        I’ll do an entire article on the topic along with a tabletop demonstration. Too much fun!

        1. Wolfe

          I look forward to seeing real world data across brands, so hope you run V/A meters both sides and oscilloscopes… I seldom trust manufacturer claims and have often found poor to just weird results in my own tests.

          1. Mike Sokol

            I just bought a 10kW load bank which will let me load anything up to 80 amps of current, while monitoring voltage drop, current, waverform, etc… Plus I’ll add reactive loads when appropriate. I’ll be bringing some of my test gear to RV trade shows and Rallys this season, so please stop by to say hi.
