Why Choose Diesel For Home Backup?

A home diesel generator gives you a practical way to keep selected essentials powered during an outage. Our range includes Hyundai and Gentech portable models, with several silenced options, electric-start models and one remote-start option.

Run Time And Fuel Economy

Diesel engines are commonly chosen where a generator needs to run for long stretches. Actual run time depends on the model, tank and load, so always check the details of the diesel generator for home use you're considering.

Keeping Noise Down Around The House

Noise matters, particularly in a suburban street. Several diesel backup generators in this range are silenced, giving you options to consider when noise is an important part of your decision.

Sizing A Diesel Generator To Your House

Wondering what size diesel generator to run a house? Start with what you actually need to keep powered rather than choosing on size alone.

Essentials First, Then Start-Up Loads

List the essentials you want to power, such as your fridge, lights, router and fans. Add up their running watts and starting watts, then leave headroom for start-up loads.

This gives you a clearer idea of the output you need when comparing the best diesel generator for home backup for your requirements.

Single-Phase Or Three-Phase At Home

Many homes have single-phase power, while some larger properties, sheds and workshops have three-phase. Check your switchboard or ask a licensed electrician which you have. Two models in this range are three-phase.

Using It When The Power Drops

These are portable generators designed to be started when the power drops. Some have electric start, while one model includes remote start.

Starting It And Connecting It Safely

Follow the maker's instructions when starting your generator. A licensed electrician should connect a generator to your home's wiring.
