Need a generator that fires up when you need it and keeps running all day? Maxwatt builds reliable petrol and diesel gensets that tradies, landscapers, and serious DIYers count on for dependable site power. Whether you're running tools on a job with no mains supply or keeping the shed lit during a blackout, these generators deliver the watts without the fuss.
From compact inverter models like the MX4500IS and MX6000IS through to heavy-duty units like the MX8000IS and MX9000ES, there's a genset that matches your power needs. Inverter models give you clean, stable power for sensitive electronics, while open-frame generators push higher output for demanding gear like welders, compressors and site lighting.
Diesel models are built for extended run times and fuel efficiency, making them a smart choice for contractors who need hours of continuous power without constant refuelling. Petrol units offer quick starts and lighter weight for jobs where you're shifting the generator around regularly.

Maxwatt generator FAQ
What size Maxwatt generator do I need?
The size you need depends on the total wattage of the tools and equipment you'll be running at once. Add up the running watts of everything you plan to power simultaneously, then add a safety margin of around 20%. For example, if you're running a circular saw (1800W), work lights (500W) and a radio (50W), you'd need roughly 2800W of continuous output, so a model like the MX4500IS would cover you comfortably. Always check start-up surge requirements for motor-driven tools, as these can spike higher than running watts.
Are Maxwatt inverter generators quiet?
Yes, inverter models like the MX4500IS and MX6000IS run quieter than traditional open-frame units thanks to advanced engine design and sound-dampening housings. Noise levels typically sit around 58–65 decibels at quarter load, which is comparable to normal conversation. This makes them ideal for residential sites, events, or anywhere noise restrictions apply. If you're working in wide-open spaces or industrial zones where noise isn't a concern, open-frame models like the MX9000ES push higher output but run louder.
How long will a Maxwatt generator run on a tank of fuel?
Run time depends on the model, fuel tank size, and the load you're drawing. Here's a rough guide:
Smaller inverter models (MX4500IS, MX6000IS): 8–10 hours at 25% load
Mid-range units (MX8000IS): 6–8 hours at half load
Heavy-duty open-frame models (MX9000ES): 10–12 hours at 50% load with larger tanks
Diesel models typically stretch run times further due to better fuel efficiency, especially under sustained loads. Always check the manual for exact specs based on your specific model and operating conditions.
Can I use a Maxwatt generator for home backup power?
Absolutely. Models like the MX6000IS and MX8000IS work well for home backup, covering essentials like fridges, lights, phone chargers, and even some heating or cooling depending on your setup. Inverter models are ideal if you're powering sensitive electronics like computers or medical equipment, as they produce clean sine wave power that won't damage circuits. Make sure you use a transfer switch to safely isolate your home from the mains grid before connecting the unit; never backfeed into your switchboard.
What's the difference between petrol and diesel Maxwatt generators?
Petrol models are lighter, start faster, and suit jobs where you're moving the generator around regularly or running it intermittently. Diesel units burn fuel more efficiently, run longer per tank, and handle continuous heavy loads better, making them the go-to for extended site work or commercial applications. Diesel engines also tend to last longer under regular use, but they cost more upfront and require slightly more maintenance. If you're after portability and convenience, go petrol. If you need endurance and fuel economy, diesel's your answer.
