Overview#
The MQ Power DA7000 WhisperWatt is a compact 7 kW standby (6 kW prime) portable diesel generator built around a Kubota Z482-E3B — a 0.479L 2-cylinder vertical diesel. It's the only WhisperWatt that runs at 3600 RPM, which is a direct consequence of the tiny engine displacement: the Z482 needs the higher speed to produce enough power.
The 120/240V switchable output gives it more flexibility than the 120V-only DCA-6, making it practical for residential applications where 240V circuits exist.
Kubota Z482 — the micro-diesel#
The Z482-E3B is Kubota's smallest diesel engine, commonly found in utility vehicles and small industrial equipment. It's Tier 4 Final certified, meaning no aftertreatment complexity — the engine meets emissions standards through combustion design alone at this displacement.
Common applications#
- Residential emergency backup (120/240V switchable)
- Small construction tools on noise-sensitive sites
- Mobile work trailers and temporary offices
- Remote equipment power
