Yanmar Portable Diesel Generators
Yanmar Portable Diesel Generators: Mobility with Diesel Reliability
A Yanmar portable diesel generator gives buyers the fuel efficiency and long engine life diesel is known for, without committing to a permanent standby installation. This collection covers the YDG3700W and YDG5500W for standard 60Hz use, the YDG5500N export model built for 50Hz markets, and two larger options, the 5kW MEC5 and a used 25kW trailer-mounted unit, for buyers needing more capacity while still keeping mobility as a priority.
YDG3700W and YDG5500W: The Core Portable Range
The YDG3700W delivers 3,700 watts in a self-contained portable package, suited to lighter home backup or job site use, while the YDG5500W steps up to 5,500 watts for buyers needing more continuous output. Both remain genuinely portable, movable between a home, job site, or wherever backup power is needed most, distinguishing them from Yanmar's stationary Maspower-branded standby line.
The YDG5500N: Built for 50Hz Markets
For buyers operating equipment or in regions requiring 50Hz power rather than the standard 60Hz used across most of the collection, the YDG5500N export model delivers the same 5,500 watt output configured specifically for that frequency standard. This matters for compatibility with certain international equipment or markets where 50Hz is the expected standard rather than an interchangeable option.
Scaling Up: The 5kW MEC5 and 25kW Trailer Unit
The MEC5 brings a three-phase industrial configuration into this portable-adjacent range at 5kW, while the used 25KW Diesel Generator on Trailer offers substantially higher output in a trailer-mounted format, a different kind of mobility than the smaller wheeled portable units. Buyers needing more than 5,500 watts while still wanting to move the generator between locations should look toward this trailer-mounted option rather than the standard portable YDG models.
Frequently Asked Questions
Do I need the standard YDG5500W or the YDG5500N export model?
The standard YDG5500W is built for 60Hz power, the standard used throughout North America and most of the markets this collection serves, while the YDG5500N is specifically configured for 50Hz, required for certain international equipment or regions. Unless you have a specific 50Hz requirement, the standard 60Hz YDG5500W is the correct choice for typical US-based home or job site use.
Is the MEC5 actually portable, or is it closer to a stationary industrial unit?
The MEC5 sits in a middle ground, it's a genuine industrial-grade unit with three-phase output, but it's positioned in this portable collection because it offers more mobility than Yanmar's larger stationary Maspower standby generators. Buyers wanting true lightweight portability should look toward the YDG3700W or YDG5500W instead, while the MEC5 suits those needing three-phase industrial capability with somewhat more flexibility than a fixed installation.
Is the used 25kW trailer unit a reliable option compared to buying new?
A used unit offers meaningful cost savings but comes with unknown wear history and typically limited or no warranty coverage compared to a new purchase. If budget is the primary concern and you're comfortable with that uncertainty, the trailer-mounted option provides access to significantly higher output than the standard YDG models at a relatively lower price; if warranty coverage matters more, it's worth comparing against Yanmar's stationary Maspower units at similar capacity.
