Standalone Solutions
Reliable Power Beyond the Grid
Living or working in remote NT locations often means mains power isn’t available—or isn’t reliable. That’s where off-grid solar systems come in. Inland Electrical has been designing and installing off-grid systems in Darwin and surrounds since 2001, providing safe, dependable energy where the grid can’t reach. These systems combine solar panels, batteries and backup generators to deliver consistent power, even through storms or long stretches of cloud.
Every off-grid setup is tailored to the site, with careful planning to meet daily demand, ensure redundancy, and keep costs manageable. Built to handle the harsh Top End climate, our systems give peace of mind that you’ll always have the power you need. Call 0407 798 698 today to talk about an off-grid solution for your property.

Energy Independence Made Simple
An off-grid system isn’t just about being independent—it’s about having confidence that your power supply won’t let you down. Professional design considers everything from load profiling and days of autonomy to weather impacts and maintenance access. This ensures your system is sized correctly and operates efficiently year-round.

Modern off-grid systems use hybrid inverters, lithium battery banks and intelligent monitoring to keep track of performance. Remote access allows you to check usage and receive alerts, while robust hardware and cyclone-rated mounting systems provide durability in NT conditions. With a well-designed setup, you can run household appliances, business equipment or even entire stations without worrying about outages or unstable supply. Off-grid power offers true energy independence with long-term reliability and sustainability.
FAQ
Everything You Need To Know
How do off-grid solar systems work?
Off-grid systems generate electricity from solar panels, store excess power in batteries, and use inverters to run household or business loads. A backup generator is often included for periods of low sunlight or high demand. This combination ensures a constant, reliable supply of electricity without any connection to the main power grid.
How much battery storage is needed for an off-grid system?
The amount of storage required depends on your daily electricity usage, the number of days of autonomy you want (how many days the system can run without sunlight), and your generator backup strategy. Most systems are designed to cover at least 2–3 days of usage to stay reliable during cloudy or wet weather.
Are off-grid solar systems more expensive than grid-connected systems?
They generally cost more upfront because they require larger battery banks and backup generators. However, for remote properties, the cost of extending the grid is usually far higher. Over time, an off-grid system provides significant savings compared to relying on diesel generation or paying for costly infrastructure extensions.
