The Unique Yamaha Advantage

Light, quiet, portable and easy to use…

Yamaha generators are quickly becoming the industries and serious campers workhorse of choice.

Yamaha’s portable range of 4-stroke petrol powered inverter generators are the new wave in generator technology for when you need clean, high quality electricity in a compact and light weight package. This means they are easy to transport whether operating equipment in the field, four-wheel-driving, camping, fishing, using power tools or overcoming a power outage.

What is an Inverter System?

An Inverter System stabilizes the amount of voltage and frequency produced by a petrol-driven alternator through the supply of “sine wave” electricity. That’s why Yamaha inverter generators are the ideal power source when using precision equipment or microcomputer controlled electrical appliances.

More controlled, clean power

Yamaha’s Inverter System produces AC current within a controlled electrical circuit process, known as PWM (Pulse Width Modulation). As a result, fluctuations in engine speed do not affect the voltage or frequency of the electrical output while at the same time reducing output emissions.

Multi-Polar alternator system

The adoption of a Multi-Polar Alternator enables the generation of more efficient, high-frequency, 3-phase AC current that the inverter then turns into single phase electricity. The high efficiency alternators on a Yamaha inverter achieve a much lighter and more compact generating unit than conventional 2-pole rotor type alternators.

Economy idle control

Bringing along a generator was never quieter or easier. That's why Yamaha created Smart Throttle™, a feature that automatically adjusts the engine speed to precisely match the load. Smart Throttle™ allows the generator to run quietly while increasing fuel efficiency, prolonging engine life and extending running time between refuelling.

Advanced sound reduction

Generating electricity used to be a noisy task. That's why Yamaha created Noise Block™, an acoustically engineered sound reduction system. Noise Block™ technology utilises various sound absorbing materials, moulded cases, an intake silencer, fibre glass insulation, plus uniquely designed mufflers and fans to provide virtually silent running whilst maintaining quality performance. It also reduces electrical interference with TV and radio signals.

Less than 2.5% distortion ratio

This means Yamaha inverter generators can be used with equipment that requires stable frequency and voltage, as defined by an ideal “sine wave” when graphed, like products with built-in computer functions and microcomputer controlled equipment (e.g. power tools and projectors).

1. What do you need to power?

The first question when selecting a generator to meet your requirements is “What am I wanting to power, both now and in the future?”

2. Make a list

Make a list of the appliances, tools and lighting that you want to use simultaneously. How many lights will you need to run alongside your powertools? Will you need to run the oven as well as the microwave at the same time?

3. Note the wattage required

The list on the previous page offers a guide on the wattages used on most common appliances and items used at home and in the workplace. For exact figures we recommend you check the nameplate or instruction manual for your individual appliances. Also listed (where applicable) is the “starting wattage” or “surge wattage” which is the amount of wattage needed to start an appliance with a motor. This may be up to three times the wattage required to run the appliance, so this must be taken into consideration.

All generators also have a maximum and rated wattage output. Rated power is the level where the generator can be operated continuously. Yamaha generators, due to the fact that they are built super strong, can handle peak start-up current requirements well in excess of other models on the market. However it pays to be aware that tools like compressors have very high (up to three times) start-up current requirements that need to be allowed for.
