When The Grid Stops
Your Costs Start
In Western Australia, many areas lie beyond reliable grid access. Connecting can cost $30k–$200k per km, while running diesel generators is expensive and inefficient. Standard solar alone often isn’t enough for harsh conditions—making well-designed off-grid renewable systems a smarter, more reliable solution.
$30k-
$200k/KM
Grid Extension
Western Power's quoted cost to extend a line to a remote property. Often more expensive than a complete off-grid system.
$55k-
$100k/YR
Standard Diesel Cost
Typical 24/7 fuel + service cost for a remote site running on diesel alone — and the engine wears out faster running at part load.

Renewable Share Possible
Properly designed solar-wind-diesel hybrids consistently deliver 90%+ of energy from renewables, with diesel as backup only.

STAND ALONE SOLAR + BATTERY
The Straightforward Off-Grid Solution
For most remote homes, the ideal setup is simple: a well-sized solar system, lithium batteries with multi-day backup, and a small generator used only when needed. We design based on your usage, use premium components, and plan for worst-case conditions—so the generator runs only a few times a year.

HybridGEN - Patented Hybrid
Power Pack
HybridGEN is Regen's own renewable hybrid power pack — a factory-wired cabinet that combines solar PV, optional small wind, lithium battery storage, and our patented variable-speed generator. It replaces a standard fixed-speed diesel generator with a system that runs the engine only when it's needed, only at its most efficient speed, and only after the renewables have done their job.
The result: 30–60% reduction in diesel consumption versus a conventional diesel system, longer engine life from running at optimum load, stable voltage and frequency across varying solar and wind input, and a system that ships in a fully wired enclosure — drop in, connect, and run.
Why Standard Diesel Fails On A Part-Load Site
Diesel generators are typically sized to peak demand. But for most remote sites, peak demand happens for a few hours a day — most of the time the engine is loafing at 20–40% of its rated capacity. At low load, three things go wrong: fuel efficiency drops sharply (more litres per kWh produced); incomplete combustion causes wet stacking and cylinder glazing (engine wears out faster); and voltage and frequency become unstable as renewable inputs vary. HybridGEN's variable-speed generator runs the engine at the speed that matches the current load — extending engine life, cutting fuel consumption by 30–60%, and stabilising power quality even when solar and wind inputs swing.

SOLAR-WIND-DIESEL MICROGRID
When a single power pack isn't enough — a microgrid that travels with you.
For mining and exploration camps, resorts, remote communities, and fringe-of-grid commercial sites, a single hybrid pack isn't sufficient. A microgrid is. We design and supply fully containerised, portable, and fully operational microgrid systems from 15kW to 150kW per container — and multi-container designs scale to a megawatt or more. Our microgrids combine solar PV, optional wind generation, lithium battery storage, and a variable-speed diesel/gas generator running our patented control technology. They're built for the cyclones, dust storms, and extended wet-weather events typical of northern WA. They've been proven in remote islands of the Republic of Maldives, in Singapore, in resorts in Australia and Sri Lanka, in schools, and in medical centres.

An Off-Grid Story
You Can Verify
Off-grid systems are bought on trust. The site is remote, the buyer can't always inspect the work, and a system failure 800km from Perth is expensive. Here's how we earn that trust — verifiable, documented, decades-long.

Six Steps
Every Step In House
Off-grid projects are engineering jobs more than installation jobs. We run a six-step process from first call to handover. The early steps are deliberately heavy: getting the site analysis and the load profile right is what makes the system reliable for the next 20 years.
FAQ
Entries
Off-Grid FAQs
Often, yes. Western Power’s quoted cost to extend a line to a remote property is typically $30,000–$200,000 per kilometre. If your nearest line is more than a few kilometres away, an off-grid system is usually cheaper to install — and you have no power bills, no demand charges, and no exposure to grid outages thereafter.
