Compare Silent Diesel Generators by Power, Price, and Features

Every setup is different — so choosing the right silent diesel generator depends on how much power you need, how much you want to spend, and how quiet you want it to run. Our range covers everything from compact 5kVA silent diesel generators to heavy-duty, high-output models used on worksites and farms. You'll find performance specs, decibel ratings, and real silent diesel generator reviews to help narrow down your shortlist.

Choosing the Right Power Output (kVA) for Your Needs

Start with how you'll use it. A 5kVA silent diesel generator is ideal for small homes, sheds, or caravans, handling essentials like fridges, lights, and small tools. For businesses, workshops, or job sites, step up to 10kVA or higher for dependable backup or full-day operation. The key is matching the load to your usage — too small and it strains, too big and you waste fuel.

Silent Diesel Generator Price Guide

Silent doesn't have to mean expensive. Prices vary depending on size, engine quality, and added features like auto-start or weatherproofing. Entry-level silent diesel generators for sale start around the low-thousands, while industrial-grade models with super-silent casing and extended runtime will sit higher. Always balance price and reliability — it's worth paying for proven brands and after-sales support.

Silent vs. Super Silent: Understanding Noise Levels

Not all "silent" generators are created equal. Standard silent units run between 65–75dB — like normal conversation — while super silent versions drop closer to 55dB. That's quieter than a lawnmower and perfect for silent diesel generator for home use where noise matters most. If you're working near others or running it overnight, check the decibel rating before you buy.

Finding the Best Silent Diesel Generator for Your Application

No matter where you need power — from a family home to a remote site — a silent diesel generator gives you steady, efficient energy without the racket of petrol models. Below are two main categories to help you pick.

Silent Diesel Generators for Home Backup

Perfect for blackouts, bush properties, or off-grid living. These generators are compact, efficient, and designed to run household essentials with minimal noise. Look for automatic start features and fuel-efficient engines for peace of mind when the power drops.

Heavy-Duty and Industrial Silent Diesel Generators

Need something that can handle tools, pumps, or site cabins? Industrial units are built for endurance and safety. They're designed for reliability in tough conditions, offering excellent noise insulation and large fuel tanks for extended runtime. A best silent diesel generator here means one that works hard, day after day, without fuss.


Silent Diesel Generators FAQs

What are silent diesel generators used for in Australia?

Silent diesel generators are built for situations where you need reliable power without the racket - think caravanning, camping, job sites near residential areas, or running essential gear at a remote property. True Gear stocks models suited to everything from RV trips to worksites that need single or three-phase power.

How quiet is a silent diesel generator?

Standard silent (or 'enclosed') diesel generators typically run at 65-75dB - roughly the noise level of a normal conversation. Super-silent models drop to around 55dB, which is barely noticeable in the background. The enclosure is what makes the difference compared to open-frame units.

What size silent diesel generator do I need for home or RV use?

For a caravan or RV, a 6-8kVA unit is usually plenty - enough to run air conditioning, a fridge, lights, and charge devices simultaneously. For a home backup or larger worksite setup, you might want 8kVA or more, especially if you're running power tools or a 3-phase setup.

What brands of silent diesel generators does True Gear stock?

True Gear stocks silent diesel generators from Macfarlane Generators and Gentech, including Yanmar-powered models. The range covers 6kVA through to 8kVA and includes inverter, AVR, and welder generator options - with both single-phase and three-phase units available.

How much does a silent diesel generator cost in Australia?

Prices vary depending on output and features. At True Gear, silent diesel generators range from around $6,900 for a quality Yanmar-powered 6.8kVA unit up to $20,999 for a premium 8kVA RV-grade inverter generator. Diesel units cost more upfront than petrol but are cheaper to run long-term and better suited to continuous use.
