EF2400IS – 2200W INVERTER GENERATOR – 2200W Petrol Yamaha Inverter Generator

If you’re looking for a top of the line generator for your caravan or motor home, then look no further than the Yamaha EF2400iS. It’s a powerful unit, delivering a maximum output of 2400W and continuous of 2000W, making it a common choice for those wanting to run some larger appliances on the road such as air-con units, microwaves or washing machines. It is suited to run most caravan air-con units on the market, as many a/c units will peak at more than 2000 watts. In fact, the EF2400iS was the winner of the Caravan & Motorhome On Tour Magazine’s Mega Portable Generator Comparison, whereby they tested 13 portable generators across six brands.

Despite its powerful output, this unit’s sleek and lightweight design still makes it mobile to move around at your convenience. Additionally, the large engine capacity does not mean this is a noisy machine – quite the opposite: the Yamaha noise reduction technology means it only produces a mere 53 decibels! That makes it quietest in its class.

Like all units in the Yamaha inverter range, the voltage produced is pure sine-wave, making it perfect to run all your sensitive electronic appliances such as laptops, tablets, televisions and mobile phones. Also included is the sophisticated Yamaha Smart Throttle technology which controls the engine speed in line with the required output, ensuring maximum fuel efficiency – it will run for 9 hours at a quarter load.

Yet another feature on this model is the Twin Tech capability to give you more power if required: you can simply hook up two EF2400iS generators together and they will produce almost double the maximum power output and provide 3800 watts of continuous power. To complete the perfect package, the unit is equipped with spark arrestor and a low oil shut-off system as important safety features.

Yamaha is one of the world leaders for engines and power equipment, and for your peace of mind their generators come with a 4 year warranty and are backed by a national service network of over 200 accredited service agents. This unit is not only the premium choice to run your Caravan, but many customers also select this model to run their fridges, lights and other small to medium home appliances during a blackout.
