Generators for Home and Property Systems

Generators for Home and Property Systems

A backup generator is close to essential for home and property stand-alone solar. You can choose to down without but doing so may triple the cost of that system.

Generators for home and property systems are often needed as it is rarely feasible to size such a system for a 100% reliable solar supply. It is rare to have no input, but there will be days when solar input alone cannot cope.

Having solar and battery capacity for 95% of the time is readily feasible but extending that to 98% may triple the cost! That 95%, however, still leaves about 18 days a year where solar will not cope. Having a generator also provides emotional comfort.

Generators for Home and Property Systems

The most-used approach is a back-up petrol or diesel generator, but LP gas versions are also available. You need one big enough to run a few essential items directly – but primarily for battery charging. You use the generator’s 110 or 230 volts to drive a suitably scaled battery charger.

For homes and small properties, the larger Honda/Yamaha petrol-powered inverter generators used in up-market RVs are adequate for occasional use. For use to routinely charge batteries, the smaller diesel-power generators last far longer. Where noise is an issue with generators for home and property systems, Onan (Cummins) has a range of quiet units. These include generators that run on LP gas.

A few properties have a large diesel like the 25 kW Cummins Triton unit (below) scaled for massive (but rare) loads. Often essential for the larger outback properties areas but cheaper to hire a big mobile unit for a day or two for those with convenient city access.

Generators for Home and Property Systems – how to find out more

Full details of suitable petrol, diesel and LP gas generators are in our book Solar Success. This, as well as our other books: Solar That Really Works! (for boats, cabins and RVs), and Caravan & Motorhome Electrics for all aspects of the topic are now available in directly-downloadable digital form from our Bookshop. Print versions are available via all bookshops in Australia and many in New Zealand – and via email (right now) from booktopia.com.au.
