With thousands sold, the Ramsond Sinemate 1500 is one of the most popular portable digital inverter sine wave gasoline generators in the market today. Advanced engineering and state of the art manufacturing techniques put the Ramsond Sinemate 1500 in a class of its own. It is one of lightest and quietest portable inverter generators in the market. Yet, despite its small size and weight, the Sinemate 1500 packs a heavy punch; with a newly upgraded 4-stroke engine, delivering engine power which translates to maximum surge output of 1000 Watts of power for the generator set. Ramsond's digital inverter sine wave technology also ensures delivery of highly stable and constant voltage to ensure the safety of sensitive appliances and equipment. Furthermore, the digital inverter technology makes this generator far more fuel efficient and environmentally friendly than conventional generators.

Suitable both as a stand-alone generator for use in home, RV, camper or office, as well as a portable power source at project/industrial sites, this highly versatile inverter generator system has been designed to meet the quality and safety demands of variety of applications. Ramsond Sinemate digital inverter generators are perfectly suited for many applications, including:

  • Residential / Office / Vehicle Backup and Emergency
  • RV, Mobile Homes, Trucks, Tractors, Cars
  • Camping, Tailgating
  • Marine Applications (Boats and Yachts)
  • Commercial and Industrial Applications
  • Mobile Power for Tools and Machinery
  • Construction Sites
  • Mobile Command Centers
  • Mobile Medical Clinics
  • Remote Scientific and Research Sites
  • Mobile Laboratories
  • Disaster Relief Modules
  • Temporary Disaster Shelters
  • Mobile Water Purification Systems
  • Telecommunication, Surveillance Towers
  • Oil Platforms, Research Sites,
  • Defense and Military Applications
  • Exhibition Booths, Concessions Stands
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.

Pure Sine Wave Inverter Generator vs Modified Sine Wave

Ramsond Sinemate 1500 Sine Wave Inverter Generator is extremely compact and lightweight. Equipped with a carrying handle and weighing only 29 pounds, it can easily be transported.
Sinemate 1500 portability

Ramsond Sinemate 1500 is extremely user-friendly. The recoil start is designed to operate with minimal force and can usually start the generator after one or two pulls*. The controls are also simple and user-friendly. So, regardless of your intended use, the Sinemate inverter generator is an all-around convenient and easy to use equipment.

*May require priming and additional pulls on first start or after extended periods of dormancy.

The multi-function control panel of the Sinemate 1500 inverter generator is designed with both functionality and safety in mind. It is equipped with a standard NEMA 120 volt sockets (standard for US and Canada), as well as a "\ /" style 12 Volt, 8.3 Amp, DC sockets. Matching 12 Volt DC plug and wire clamps are included for battery charging. The AC socket is protected with a spring loaded flip cover for safety. Furthermore, the switches (ON/OFF and Economy Mode) are protected with removable clear seals for added safety and protection against water and moisture.

  1. great 5 Star Review

    Posted by on 4th Jan 2014

    I got this generator to have as backup emergency power on my 35ft sailboat for if the batteries went flat. I have needed it twice now and it performs just fine, it runs my ten amp battery charger with no problem. I saw a comment from one reviewer that said his leaked oil, well in the instruction manual it clearly states that if you overfill the oil this will happen. Comparing this unit to the Honda 1000 at half the price it does the job and even matches the color of my power cords (ha).
