How many watts do I need to power my whole house?"

The 24kW Generac shown here covers whole-house needs for homes around 2,000–3,000 sq ft — running central AC, fridge, furnace, well pump, and standard circuits at the same time. For a larger home or bigger AC unit, it's worth running Generac's online sizing calculator or getting a load calculation from an electrician to confirm this size fits.

What do I actually get for the price — what's the value here?"

Connectivity/mobile link — monitor and control the generator remotely from a phone app

24/7 customer support — help available anytime, especially useful during an actual outage

Free 5-year warranty — real peace of mind, since standby generators are a long-term investment

Made in the USA — often means easier parts availability and consistent build quality

How does it work when the power goes out — is it really automatic?"

Yes — this is a standby unit, meaning it's permanently installed and wired into the home's electrical panel with an automatic transfer switch. It senses an outage and starts itself, typically restoring power within 10–20 seconds, with no manual action needed.

This is my second generac as i had one in my old house, the piece of mind is priceless. Every week it exercises an every time it does i feel protected

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).
