No.1 in Ease of Use.All-in-one Control Panel

EF2000iS is No.1 in ease of use.

As with the popular EF2400iS, all the starter and control functions are gathered in one place on the front panel. You can do all the operations to start and run your EF2000iS from the same position.
We have positioned the re-coil type starter pull and switch panel for easier access.

Retro-modern Styling

Beautiful design to match in any leisure usage.
New retro-modern styled re-coil starter protection ring.

With the new EF2000iS, Yamaha has created a new design identity that fits a handy inverter series.
The aim was to create design that is emotional with reminders of the good old days and new value at the same time.
This is how the new EF2000iS design was born, with a nostalgic round form and functional geometrical design combining to create retro-modern styling.

Parallel Use Function for Wider Range of Uses

This model is outfitted with a parallel-use function as standard equipment to enable the use of two generators to accommodate a wider range of uses (widened range of output needs).
You can connect two units of EF2000iS by using the optional terminal unit assy.
Professional users operating a variety of precision devices sometimes need a little more output.
With the EF2000iS you can connect two units to get the added output for a variety work uses.
