Continuous power is the amount of power delivered while the battery has enough charge. One of the most promising alternatives to lithium-ion, this type uses a pumped electrolyte (such as zinc bromide or vanadium ions) and chemical reactions to store charge and release it again. You should probably choose to allow only critical household circuits to operate in that situation, such as the fridge and lighting (and that might require extra wiring work). A storage battery is likely to be drained very quickly if it also has to run things such as a pool pump or underfloor heating, which can draw a lot of power. In addition to the federal initiative, here are the current battery-focused rebates or loan schemes available by state and territory.
That means you can use your own solar energy at night when electricity is usually more expensive. You can even estimate your potential savings with our Battery Payback Calculator.

For example, a Tesla Powerwall (13.5kWh) can cost around AUD $15,500 when installed, while a 10kWh battery from Keheng brand (battery only) might be closer to AUD $2000. Newer brands like BLUETTI and Alpha ESS also offer great value for money, featuring modular designs and IP65 weatherproof protection. A Virtual Power Plant (VPP) is a network of home solar batteries, solar panels, and other energy devices that work together to support the electricity grid—kind of like a team of mini power stations. Thanks to recent federal and state rebates & incentives compounding with the continued falling costs, are solar batteries worth it in 2025? Thanks to rebates and cost drops, many households are finding they are for many homes. If you’re adding a battery to an existing solar system, it might be cheaper than if you need to install a new inverter as well.
Learn how lithium battery warranties work, including end-of-life capacity, energy throughput limits, and how to avoid voiding your home solar battery warranty. Understanding the warranty terms of your battery is essential to ensuring you get the performance and lifespan you expect. Plus, we explain the impact of overnight grid charging and how you can adjust system settings as your battery ages. However, the usable capacity may differ from the total battery capacity. Generally, the usable capacity is limited to 80 to 90% of the total battery capacity to increase the lifespan and avoid a potential battery shutdown at very low charge levels. For example, a lithium battery with a 10 kWh total capacity may have its usable capacity limited to 80%.
