If you have used a traditional/conventional generator, you have probably experienced that when there was a fluctuation in the power, the lights dimmed and then went back to full power. This fluctuation of power is quite dangerous to many modern-day high-tech and sensitive equipment. For example, if your computer was powered by a conventional (non-inverter) generator and the voltage fluctuated, the computer would shut down prematurely. This premature shut down not only causes inconvenience, but often leads to loss of unsaved data and files. Furthermore, sudden fluctuations of power can often be fatal to many of these types of equipment. You will not experience this fluctuation of power using an inverter generator.

How it Works

An inverter generator produces 3-phase AC power at a high frequency. This high frequency AC Power is then converted to DC power. In a final step, the DC power is then inverted back to AC at 120 volts, 60hz for use by common appliances and equipment.

How Inverter Generators Work

Intelligent Throttle Technology (Variable Speed Operation)

In contrast with the traditional generators that run at a constant RPM/speed, Ramsond Sinemate portable inverter generators are equipped with microprocessor controlled Intelligent Throttle Technology which automatically adjusts the engine speed to precisely match the load. So, if the generator is not powering many appliances, it runs at a lower engine speed. This allows the generator to run quieter while increasing fuel efficiency, increasing engine life and extending running time between refueling. Once the load is increased, this inverter generator increases the speed and RPM automatically to meet the demands of the load. The variable speed feature of the Ramsond Sinemate inverter generators provides many advantages, some of which include:

  • Increased Life Span Due to Decreased Engine-Wear.
  • Lighter Weight and Compact
  • Fuel Efficient and Economical to Operate
  • Quiet Operation
  • Environmentally Friendly

Quiet Operation

Ramsond Sinemate inverter generators are much quieter than conventional generators. This is because the Sinemate inverter generators do not run at full speed all the time. As mentioned, the Sinemate inverter generator is controlled by a microprocessor so it only produces what is needed at any given time.

Ramsond Sinemate inverter generators are even much quieter than many other inverter generators in the market. Ramsond Sinemate inverter generators are equipped with sound dampening insulation materials that further decrease the level of noise even when running at full speed and maximum load.

The quiet operation of the Ramsond Sinemate inverter generators makes them a perfect candidate for use in RV's, boats and at campgrounds, recreational sites, exhibition booths and concessions stands.

Ramsond Sinemate inverter generators produce pure (true) sine wave power, the same type and quality of AC (Alternating Current) power produced by the utility grid. Pure sine wave output is a far superior (cleaner) form of output power as compared with modified sine wave or square wave power. Increasingly, most modern electrical or electronic devices such as laptop computers, stereos, laser printers, sensitive medical equipment, digital clocks, kitchen appliance with multi-stage timers, and variable speed or rechargeable tools can only function properly with pure (true) sine wave power. Similarly, pure (true) sine wave inverter power may be needed for maximum efficiency of inductive equipment, to reduce audible and electrical noise in devices with audio-visual components and to enable proper functioning of fluorescent lights with electronic ballasts.

Ramsond Sinemate inverter generator's pure sine wave output provides suitable power for operation of all electronic and electrical appliances and devices, whereas the inferior, conventional generators produce modified or square wave power. These conventional generators are not capable of providing suitable power to many devices.  Both the function and longevity of electrical/electronic devices and appliances are improved with the use of pure sine wave power.

30 Amp Receptacle

The multi-function control panel of the Sinemate 2500 is designed with both functionality and safety in mind. Upgraded from the previous generation, the new Sinemate 2500 panel is now equipped with one standard NEMA three prong 15 Amp 120V socket (standard for US and Canada), and a 30 Amp, 120V L5-30R receptacle , which makes it possible to use this generator to run virtually any appliance, including many RV appliances and air conditioners*. The panel is also equipped with a "\ /" style 12 Volt, 8.3 A DC socket for battery charging (12 Volt DC plug and wire clamps are also supplied). The ECON (Economy Mode) button, when turned on, allows the generator to run at a lower idle speed to conserve gasoline.

Product Reviews

  1. Worked well for our hurricane emergency but typi 4 Star Review

    Posted by on 14th Mar 2020

    I had purchased this generator for emergency use and then left it with no fuel after a little hurricane passed us by. A year later and Michael blows the roof off. After removing the leaking fuel cutoff switch and cleaning the carb this little generator ran our refrigerators and lights and everything else we threw at it for over a month. We only stopped it to add fuel. I hadn't even changed the factory oil. Definitely a lifesaver. And since no gas stations survived the storm having this little guy sip fuel was a blessing. In getting it ready for the next storm I've had to replace the cracked primer bulb and some of the clips on the fuel lines. It starts easily and runs like a champ. The skinny 12V starter battery is a bit hard to find but I'm very pleased overall.

  2. Very reliable generator 5 Star Review

    Posted by on 16th Jul 2019

    I now have 700+ hrs on mine and it starts right up and runs great. I have a sharpening business and this powers my portable trailer with all the tools and all the lights just fine. Nice and quiet too.
    A great, reliable generator.

  3. Best Bang for the Buck. Plenty good enough and then some. 5 Star Review

    Posted by on 8th Apr 2016

    Sure, we'd all like to have a whisper-quiet Honda 2000i, but who really wants to pay like twice the price of this Ramsond Sinemate 2500? The Ramsond's almost as quiet (my phone's downloaded decibel meter measures it at less than 60 dB at 10 feet from its exhaust side with a light load [an oscillating fan], and in the mid- to high 50s from the other sides), it has electric start AND an honest-to-God 30 Amp twist-type marine or RV style shore power outlet the Honda lacks, has a higher rated wattage capacity and comes with jumper cables for direct battery charging from its 12 Volt DC outlet (Honda only sells these cable as a separate pricey accessory). I lucked out and got mine in March 2016 for just $405 with free shipping on eBay. Would I recommend it? For the price? Hell yes!

  4. Emergency Power 5 Star Review

    Posted by on 22nd Jan 2016

    Bought this gen last year just before spring turkey season to power my electric blanket when camping out. Also used it to run my electric grill and coffee maker at the camp site. With the blizzard coming this weekend,I gassed it up and after 4 pulls it fired right up after sitting in the shed for the past 7 months.Light weight,quiet,long running and reliable. I named it Debbie after my wife!

  5. Outstanding Value 5 Star Review

    Posted by on 26th Nov 2014

    My RAMSOND SINEMATE 2500 PORTABLE PURE SINE WAVE INVERTER GENERATOR is a great product. It has many features that many more expensive units have at HALF the cost

  6. still running two years old 5 Star Review

    Posted by on 21st Sep 2013

    Bought the 2500 two years ago for my RV and home emergencies. Runs great, never a problem starting it even at 8000+ feet in the Sierra Nevada mountains. Price was great too.
