Battery Storage Systems
Store your solar energy for use anytime - day or night - with premium battery storage solutions
Explore Battery Options
Complete Energy Independence
Battery storage systems allow you to store excess solar energy generated during the day for use at night or during power outages. This transforms your solar system from a daytime-only power source into a 24/7 energy solution.
With battery storage, you can maximize your solar self-consumption, reduce your reliance on the grid, and gain protection against power outages. Modern lithium-ion batteries offer high efficiency, long lifespan, and smart energy management capabilities.
Whether you're looking to achieve energy independence, reduce your electricity bills, or simply have backup power for emergencies, battery storage is the key to unlocking the full potential of your solar investment.
Benefits of Battery Storage
Backup Power
Keep your essential appliances running during grid outages with automatic backup power from your battery storage system.
Maximize Savings
Use stored solar energy during peak rate periods when electricity from the grid is most expensive.
Energy Independence
Reduce your reliance on the grid and increase your self-consumption of clean, renewable solar energy.
Future-Proofing
Prepare for time-of-use pricing, demand charges, and potential grid instability with your own energy storage.

- Victorian Solar Homes Program: Interest-free loans for solar batteries
- South Australia Home Battery Scheme: Subsidies of up to $6,000 for home battery installations
- Small-scale Technology Certificates (STCs): Financial incentives for installing eligible renewable energy systems
Note: Incentives and rebates vary by state, territory, and individual circumstances. Contact us for a personalized assessment of available incentives for your specific situation.
Frequently Asked Questions
How long do home battery systems typically last?
Most premium home battery systems are designed to last 10-15 years, with warranties typically covering 10 years. The actual lifespan depends on usage patterns, depth of discharge, and environmental conditions. Modern lithium-ion batteries can typically handle 6,000-10,000 charge cycles while maintaining 70-80% of their original capacity.
Can I add battery storage to my existing solar system?
Yes, in most cases you can add battery storage to an existing solar system. The complexity depends on your current inverter setup. With a standard string inverter, you may need to add a hybrid inverter or a battery-specific inverter. If you have microinverters, you can typically add AC-coupled battery storage. We can assess your current system and recommend the best approach for adding battery storage.
How much backup power will I have during an outage?
Backup duration depends on your battery capacity and what appliances you're running. A typical 10-13 kWh battery can power essential loads (lights, fridge, internet) for 12-24 hours. With careful energy management, you could extend this to 2-3 days. Larger battery systems or multiple batteries can provide more backup capacity. During an extended outage, your solar panels can recharge the batteries during daylight hours if the system is designed for island operation.
Are batteries safe for home use?
Yes, modern home battery systems are designed with multiple safety features and undergo rigorous testing. Premium brands like Tesla, LG Chem, and Sonnen use lithium iron phosphate (LFP) or other stable chemistries that are much safer than earlier lithium-ion formulations. Safety features typically include thermal management systems, overcharge protection, short circuit protection, and fire containment measures. All our installations comply with Australian standards and are performed by certified installers.
