✅ Premium 10-Year Warranty: Backed by our ironclad guarantee on industrial-strength hardware, our systems are built to last and perform under extreme conditions.
✅ Minimal Backup Dependency: Expertly optimized designs slash reliance on petrol/diesel generators, prioritizing clean, silent solar and battery autonomy.
✅ Proven at Scale: Deployed nationwide and in New Zealand for high-stakes critical infrastructure, our solutions set the benchmark for sophistication and fault-tolerant performance.
Our Mission-Critical Off-Grid System Components
Our premium packages integrate seamlessly for high-availability performance. Every element is selected for redundancy, efficiency, and long-term durability, with static transfer switches enabling instantaneous failover between 50Hz synchronised redundant sources.
✅Microgrid Controller: Selectronics SP Pro The heart of our high-availability architecture – a robust, scalable inverter/charger that orchestrates seamless power management. Learn More about the Selectronics SP Pro
✅ Solar Inverter: Fronius Primo GEN24 SCERT-certified and optimised for Selectronics integration, delivering precise, high-efficiency AC conversion with built-in monitoring. Deployed in dual-redundant configurations for uninterrupted output. Explore Fronius Inverters
✅ Solar PV Panels: Tier-1 High-Efficiency Modules Premium monocrystalline panels from trusted brands like Sunpower, AIKO, Jinko and Trina, engineered for maximum yield and durability in harsh Australian conditions. Scaled for redundant arrays to maintain generation under any scenario. View Rooftop Solar PV Options
✅ Battery Storage: BYD Premium LVS/LVL Managed System Selectronics-approved lithium-iron-phosphate (LiFePO4) batteries with advanced BMS for safe, deep-cycle performance and 10+ year lifespan. Dual banks ensure failover without a flicker. Discover BYD Battery Storage
✅ Static Transfer Switches (STS) Industrial-grade iSTS units provide sub-cycle switching between redundant power sources, guaranteeing zero downtime during transfers. Essential for mission-critical loads like telecoms and defence systems. Learn More about Static Transfer Switches
✅ Advanced Remote Management: Enjoy full diagnostics and control from anywhere, including seamless firmware updates and automated system restarts at every stage. Our redundant alert systems and dual-comm design ensure you'll never miss a critical notification—empowering you to react and resolve issues remotely, or organise service in a flash for faster peace of mind.
✅ DC Patching Enclosures for Ultimate Resilience: In the event of a prolonged outage affecting one half of the system (e.g., exceeding 24 hours), a qualified electrician can swiftly activate the full solar array on the unaffected side of our redundant architecture—maintaining continuous power while minimising elevated risk of interruption.

Frequently Asked Questions
-
Do I need a generator for my off-grid system?
Your solar system should cover your power needs 95% + of the time, however we highly recommend a good quality, automatic start generator to ensure you have energy security and full power capacity throughout the worst days of winter.
-
Are STC rebates available for an off-grid solar setup?
Yes, STC rebates are available where you have a Fronius SCERT inverter coupled with a Selectronic SP Pro micro-grid. This is a standard solution we offer.
-
How much does it cost to go off-grid?
The cost to go off-grid will depend on your expected/anticipated energy demand. With knowledge of your energy demand we can then help you size your battery storage, solar PV, generator, microgrid inverter, etc.
It is worth noting that connecting a new block to the power grid can cost between $15,000 and $50,000 depending on the situation. And a typical energy bill for the average household is around $3000-$4000 per year (or higher in colder areas). Given the cost of grid connection and supply, a well maintained and high quality off-grid system is likely to be cheaper in the long run (20 years +), depending on your particular situation (if grid connection is >$30,000 you can pretty much assume off-grid will be cheaper).
