HOW IT WORKS
Smart Energy Storage
Solar battery systems store excess energy your panels generate during the day, allowing you to use it in the evening or during outages.
Instead of exporting all your unused power to the grid for a small feed-in return, a battery lets you keep that energy and use it when electricity is most expensive. Depending on your setup, you can also run essential appliances during blackouts or operate more independently from the grid.
We install AC- and DC-coupled battery systems, advise on single- or three-phase compatibility, and help you understand the pros and cons of popular options like lithium-ion vs. lead-acid batteries.
Every install starts with a clear discussion about your energy habits, home layout and future plans — whether that includes EV charging, expanding your solar, or simply increasing self-sufficiency.
FAQ
Everything You Need To Know
Is a solar battery worth it in NSW?
For many households and businesses in NSW, yes — especially if you're home during evenings when solar panels aren't generating. With energy prices rising and feed-in tariffs dropping, storing your own power often delivers better long-term value than exporting it. A battery also offers added benefits like blackout protection and energy independence. The return on investment improves further when paired with the right usage habits and system design.
How long do solar batteries last?
Most modern lithium-ion solar batteries last around 10 to 15 years, with warranties typically covering 6 to 10 years. Lifespan depends on how often the battery cycles, its depth of discharge, and the environment it’s stored in. Systems designed and installed by accredited professionals usually achieve the highest performance and reliability over time.
Can I add a battery to my existing solar system?
Absolutely. Many existing solar setups can be retrofitted with a battery, either using AC-coupling or inverter upgrades. The process is straightforward, but it’s important to have your system assessed by a qualified installer. They'll check your current system’s compatibility, suggest the right battery size, and ensure everything meets current standards and safety requirements.
