Cutting Ties to the Grid
What It Really Means to Go Off-Grid in New Zealand
For many homeowners in Wanaka, Hawea and the surrounding regions, the idea of cutting ties to the grid is about more than saving on power bills, it’s about independence, resilience, and control. Going off-grid means generating, storing, and managing your own power completely, without relying on the national electricity network. But is it right for you?
How Off-Grid Solar Works
Going off-grid means your home produces and manages all of its own power, without relying on the national electricity network. At the heart of a modern off-grid setup is the Sigenergy SigenStor system, an all-in-one solar, battery, and inverter solution designed for complete energy independence.
SigenStor intelligently connects your solar panels, battery storage, and backup generation through the Sigen Energy Gateway, which acts as the control centre for your home’s power. During the day, your panels charge the high-capacity SigenStor batteries while supplying household loads. At night or during cloudy periods, stored energy powers the home automatically, and if extended low-sunlight days occur, the system can seamlessly switch to a backup generator for continuous supply, no manual intervention needed.
For remote areas like Haast, Makarora, or rural Hawea, this level of automation and reliability is a game-changer. The system can operate entirely off-grid, manage power flow intelligently, and even provide remote monitoring through the Sigen app, so you can keep an eye on performance from anywhere.
The Benefits of Going Off-Grid
Modern off-grid living isn’t about compromise, it’s about control, resilience, and sustainability. With technology like Sigenergy’s SigenStor and Energy Gateway, you can enjoy seamless, high-performance power even in the most remote parts of New Zealand.
For homes in places such as Haast, Makarora, or the upper Clutha, where grid supply is unreliable or unavailable, an off-grid solar system provides continuous, self-managed power 24/7. Intelligent energy management means your system automatically prioritises solar generation, battery storage, and backup generation in the most efficient way possible.
Another exciting development is the ability to use your electric vehicle battery as part of your home energy system. With bidirectional charging, compatible EVs can discharge power back into your home, effectively becoming an extra battery source during outages or high-demand periods. When paired with the SigenStor system, this creates a flexible, high-capacity energy ecosystem, one that’s fully independent of the grid.
Key advantages of off-grid solar include:
True energy independence - no power bills, no outages, no grid dependency
Smart energy control through Sigen AI-driven optimisation and the MySigen app
Resilience for remote living, with automatic generator integration
Future-proof compatibility with EV batteries and smart home energy management
Sustainable power generation that reduces carbon emissions and improves self-reliance
Off-grid doesn’t mean going without, it means gaining freedom. With the right system, you can live anywhere in the South Island with full confidence your home will stay powered by the sun, the battery, or even your EV.
