Off-Grid Solar
Questions, Answered

We design your system based on your property’s expected maximum occupancy to protect its resale value and prevent costly upgrades later. For a typical family home, we calculate your energy needs by allowing 5 kWh per day for the house itself, plus an additional 5 kWh per person.

For example, a fully occupied 5-bedroom home with up to six people would require a system capable of handling about 35 kWh per day. Our systems are built to provide 48 hours of battery autonomy and rely on conservative winter solar estimates so you can live comfortably without relying on a noisy generator

Reliability is our main objective, which is why our larger systems feature a dual-system design. We build setups with parallel components, such as using dual inverters and split battery banks, so there is no single point of failure. If one inverter or battery goes offline, the rest of the system continues to operate independently. While the system will run at a reduced capacity, this redundancy ensures that power to your home is not interrupted while the issue is being repaired

Yes, we offer flexibility in the equipment we install. While we typically supply trusted solar panels from Jinko or Aiko, you can request any alternative brand of your choice. For inverters and batteries, we frequently recommend platforms like Sigenergy, Deye, Victron, and Solis, but we can source other reliable brands if requested. We only recommend equipment that has proven reliability in harsh Australian conditions, such as locally made modular systems from XESS Energy or high-quality lithium batteries from Pylontech, BYD, and PowerPlus

High-voltage lithium batteries (120V–800V) are ideal if you have a large solar system and plan to run heavy loads like air conditioners, pool pumps, or electric vehicle chargers. They operate with much less current than older 48V systems, meaning they require thinner cables, lose less energy as heat, and offer better round-trip efficiency. Because they can handle larger amounts of power without overloading the system, they provide faster charging and discharging during blackouts. However, if you have a smaller cabin setup, a standard 48V system might still be the most cost-effective choice

Yes, off-grid systems still qualify for several government incentives in Australia. Federal Small-scale Technology Certificates (STCs) apply equally to off-grid solar and battery installations, giving rural and off-grid households the same upfront discounts as grid-connected homes. Depending on your location, you may also be eligible for state-specific support, such as the Cheaper Home Batteries Program or zero-interest loans and battery rebates offered in regions like Victoria and New South Wales
