EF1000iS

Who would think a 27-pound generator could deliver so much 
performance and be so quiet? Yamaha, that’s who. Check out the 
Yamaha EF1000iS inverter generator – Yamaha’s Noise Block technology reduces sound output down to a whisper (you’ll hardly know it’s running).   And thanks to its compact, ergonomic design, the EF1000iS goes virtually anywhere. It’s packed with features to make life easier, like a large fuel filler opening, a fuel petcock to shut off the fuel to reduce carburetor contamination during storage , and a built-in 12-volt battery charging system for RV, auto, or marine. And thanks to Smart Throttle, it’s 
good for the long run, providing up to a 12-hour run time without refueling. 
The EF1000iS is ideal for RV AC/DC converters, running small appliances, tools and lights – it’s a powerhouse performer, right at your fingertips. 

EF2800i

Need additional power in a lightweight package for camping? The Yamaha EF2800i 
has it all – high output and quiet operation. In fact, the EF2800i is 
the quietest generator in its class. And, you’ll find it’s a powerful ally, 
whether providing back-up power at home, or electricity for the campsite, 
including powering the air conditioner on your 5th wheel or travel trailer. 
It’s also perfect for recharging batteries or running small to medium appliances, making it suitable for home back up. The EF2800i comes packed with features, like an inverter unit with Pulse Width Modulation (PWM), Smart Throttle, and an efficient overhead valve engine.  And thanks to its multipole rotor and compact stator, the EF2800i tips the scales at a mere 64 pounds, making it the lightest generator in its class. Lightweight and powerful, with clean, high-quality electrical power output– that’s the EF2800i.

EF3000iseB

Strengthening the core of our inverter lineup are the Yamaha EF3000iSE 
and the EF3000iSEB, two of the most revolutionary inverter models 
available today. Ever need a little boost - extra power that gets your 
tool or air conditioner started quickly and efficiently? Well, now you 
can get that "boost" thanks to the EF3000iSEB generator from Yamaha. 
The "B" on EF3000iSEB means it features Yamaha Boost Technology ™, 
which provides additional power when you need it. Perfect for the RV 
enthusiast, the iSEB is an ideal source of power for either a fifth-wheel 
or travel trailer system. The Boost Control Unit in the generator 
automatically senses when additional boost is needed and it uses 
power from the internal 12-volt battery to produce additional amperage. 
In fact, the additional amps boost the alternator's 3000-watt output 
for up to 10 seconds, increasing the output so it's comparable to a 
conventional 3500-watt generator. Supplying that extra boost for 10 
seconds is ample time to power equipment that may need that extra kick 
to start quickly and efficiently, such as a 13,500 btu air-conditioner 
or other trailer appliances. However, if you find yourself not needing 
that little extra kick, you can take advantage of the Yamaha EF3000iSE, 
which includes all the features of the EF3000iSEB but without our 
Boost Technology feature. Both the iSE and the iSEB include Yamaha's 
performance enhancing features, such as Inverter Technology, Smart 
Throttle and Noise Block. So both are capable of producing clean, highquality 
electricity with extremely quiet operation (quietest in the industry). 
Both units also feature a fresh, new ergonomic design with easy 
control access, effortless electric starting and built-in wheels so they're 
remarkably portable - providing convenient power to the locations you 
need it most, whether around the home or at a campsite. The EF3000iSE 
and EF3000iSEB - generators on the leading edge of technology.
