Energy Independence with the Security of Grid Support
An affordable pathway to full off-grid living
If you have dreamed of being fully off-grid, but you currently live in town or are connected to the grid, then our new Independent Energy System (IES) could be the perfect and affordable solution for you.
Pricing starts at $29,500 inc GST for an ‘average’ home.
The Power Station Independent Energy System (IES) is a new concept in independent living. Made in New Zealand, it’s a fully off-grid solar power system that can be installed in an existing grid-connected home. The grid connection is used only as a backup to top up your batteries when required—not to power your house.
With the flexibility to start more affordably and add more batteries and solar panels later, you’re in control of how much savings you want to achieve and how much money you want to spend to achieve it.
At any time, you can cut the cord completely and ditch the power bill! It’s simply a matter of adding more solar panels and battery modules.
If you’re keen to learn more, or even just a bit curious, we’re offering a Free Design Service so you can find out how the IES might work for you. Click below to get started.

The new Power Station Independent Energy System is a new concept in off-grid solar, designed for people living in town or the city.
How it Works
D uring daylight hours, energy from the sun passes through your solar panels to your Power Station Independent Energy System (IES), which is then sent back to your home’s fuseboard as usable AC power. At the same time, the battery bank inside the IES is filled by energy from your solar panels. This battery power can be accessed by your home after dark or on dark days.
Before installation, you can choose to either take power from the grid or to go fully off-grid by connecting an approved auto-start generator.
You’ll need to select one of the two backup options to top up your batteries because they’ll need it, particularly on consecutive dark days in winter.
Utilising grid power as backup usually costs 30–50% less than going fully off-grid. That’s because a full off-grid system requires extra solar panels, batteries, and an approved generator.
Need an estimate? No worries. We can usually give you accurate pricing for either option after only 15 minutes on the phone or via video call. Every Power Station Independent Energy System is customised to your situation based on your goals, your local sunshine hours, and the level of savings or independence you seek.

Pricing
Start small and grow your savings, or ditch the grid completely!
Pricing starts at $29,500 inc GST for the components for our Medium Home System (for the ‘average’ home). But for a tiny house, pricing could be as low as $15,995 inc GST.
As an example, our Medium Home System could save you up to 70% on your power bill, if you programme the grid to fill the battery overnight on low night rates. If your power use is higher than the ‘average’ home, you’ll need more panels and batteries to achieve similar savings.
Sizing and pricing can increase up to $100,000 inc GST for very large households with high daily power use, who want to be completely off-grid and 100% independent.
Every Power Station IES is customised for you and based on a few factors. These include your goals, your local sunshine hours, your power use for the last 12 months, your budget, and how much you want to save on your power bill.
If you value independence—and like the idea of this new concept as an affordable future pathway to achieve full off-grid solar, our solution could be a perfect fit.
You’re in control of how much savings you want to achieve and how much money you want to spend to achieve it. That’s why the pricing below is a guideline only.
