Generac MLG8K-STD Mobile Diesel Generator
Generac MLG8K-STD Mobile Diesel Generator
The Generac MLG8K Mobile Diesel Generator is built for dependable power, long-lasting performance, and quiet operation. Featuring a Marathon Electric brushless alternator paired with an SE350 voltage regulator, it delivers clean, reliable single-phase output with ±1% voltage regulation.
With a prime power rating of 8.1 kW / 8.1 kVA and up to 9.0 kW / 9.0 kVA standby capacity, the MLG8K is engineered to keep your operations running smoothly and without interruption — wherever the job takes you.
The Generac MLG8K Mobile Diesel Generator is powered by a 1.0L Kubota® D1005 liquid-cooled engine, EPA Tier 4 Final compliant and optimized to run at 1800 RPM for fuel efficiency and long engine life. Paired with a 56-gallon fuel tank, it delivers up to 160 hours of runtime at 50% load or 80 hours at full load — perfect for demanding jobsites and extended use.
Designed for durability and quiet operation, the MLG8K uses rubber vibration dampers and a sound-attenuated 14-gauge steel enclosure to keep noise to just 70 dB(A) at 23 feet. Automatic shutdown safeguards protect against low oil and high temperature, while a powder-coated, UV-resistant finish ensures long-lasting reliability.
The easy-access control panel includes a four-position keyed switch, hour meter, emergency stop, and individually breakered outlets (two 120V 20A GFCI duplex and one 240V 30A twist-lock).
