Complete standalone power for properties beyond the grid, or where a connection quote costs more than independence. Designed, installed and supported by the same Hunter Valley family.
An off-grid system is a small power station for one property: solar to generate, a battery bank to store, an inverter to run the house, and a generator to cover the week the weather doesn't cooperate. Get the sizing right and you forget it's there. Get it wrong and you're running the generator every winter evening. We're SAA accredited for Stand-Alone Power Systems and it's the work we've built the business on.
The four situations we see most
When the network quote to bring power up the driveway runs to tens of thousands of dollars, a standalone system is often cheaper, and you own it outright. Common around Wollombi, Broke, the Central Coast plateau and the Central West.
Homesteads, weekenders and lifestyle properties that want the house, pumps, freezers and workshop to run regardless of what the network is doing.
You're on the grid at the house, but the shed or the bore pump is 400 metres away. A small standalone system beats trenching cable.
Long outages, storm damage, bills that keep climbing. Some customers cut the cord. Others keep the connection but build a system that could run without it. We'll tell you honestly which makes sense.
Sizing matters more than brand
What actually runs, when, and what surges on start-up. Pumps, welders, air-con and cool rooms decide the inverter size, not the number of bedrooms.
We size the array for winter, not summer, and the battery bank for the number of cloudy days you want to ride through before the generator starts.
LFP chemistry only, from brands with Australian service backing: Pylontech, PowerPlus Energy, Deye. Sized for days of autonomy, not hours.
Selectronic or Victron at the heart, often with Fronius AC-coupled for the solar. A Himoinsa diesel set on auto-start covers the worst week of weather.
Our own crew of licensed electricians, proper enclosures, and a full commissioning test before we hand over.
We walk you through how the system runs, what the generator does and what to keep an eye on. After that, you call the same family that installed it.
Off-grid-grade equipment we'd run ourselves
The heart of the system. Selectronic is our default for jobs that absolutely have to keep running. Victron when the site needs something bent to fit. Fronius AC-coupled for serious solar input. Deye when budget matters.
See the inverters
Off-grid banks cycle hard every day and hold through cloudy stretches. We only fit LFP chemistries with proven Australian service, and we size for days of autonomy rather than a brochure number.
See the batteries
On a well-sized system the generator runs a handful of hours a year. When it does, it has to start first time. We fit Himoinsa exclusively, integrated with the inverter so it starts and stops itself.

Almost always yes. A generator is cheap insurance compared with oversizing the battery bank to cover the once-a-year worst case. On a properly sized system it barely runs, but on the day you need it, you really need it.
It depends on your loads and how many cloudy days you want covered, not on the size of the house. The honest comparison is against the network connection quote and the bills you'll never pay. We'll give you a written design and a fixed price after a site visit.
Yes. Some customers disconnect entirely. Others keep the grid as a backup and run a system that could stand alone. We'll tell you which one makes sense for your bill, your loads and your patience for generators.
Yes. Tired battery banks, ageing inverters, adding solar or a generator to a system someone else installed: we service and upgrade off-grid systems we didn't put in.

Off-grid country for us means the Wollombi and Congewai valleys, Broke and Bulga, the Upper Hunter around Denman and Sandy Hollow, the Central Coast plateau, and the Central West from the Bylong Valley out to Orange. Pick your area to see what we typically do there.
