We can install generators and changeover switches for backup power. Another great option for backup power is a battery bank. Not only will a battery bank provide backup power, but it will also pay for itself with energy savings when used in conjunction with solar power.

For many Australian homes and businesses, a solar battery can be worth it, especially as electricity prices rise and feed-in tariffs drop. Without a battery, excess daytime solar is exported to the grid at a lower rate, then bought back at a higher rate at night. A battery stores that unused energy so it can be used later, improving self-consumption and reducing reliance on the grid.

The overall value depends on energy usage patterns, system size and local tariffs. Properties that use more power in the evenings or want backup during outages often see the greatest benefit. While there is a higher upfront cost, long-term savings and energy independence can make battery storage a smart investment.

Most modern lithium-ion solar batteries last between 10 and 15 years, depending on usage and installation quality. Many come with warranties guaranteeing performance over a set number of years or charge cycles. Proper system design and correct installation play a major role in maximising lifespan.

Maintenance is generally minimal. Most battery systems are sealed units with built-in monitoring software to track performance and health. Occasional professional checks and ensuring proper ventilation help maintain safe, efficient operation over time.
