A home battery storage system is the missing piece that transforms your solar panels from a daytime saver into a round-the-clock energy solution. By storing surplus solar energy generated during the day, you can power your home in the evening, overnight, and during grid outages without drawing expensive electricity from the grid.
How Battery Storage Works
During the day, your solar panels often produce more electricity than your home consumes. Without a battery, that excess energy is exported to the grid at a low feed-in tariff. A battery storage system captures that surplus energy and stores it for later use โ so you can power your home during peak evening hours when electricity rates are highest.
Modern battery systems are fully automated. Intelligent software manages charging and discharging cycles to maximise your savings, and many systems can be monitored and controlled from your smartphone.
Battery Technologies We Install
- Lithium Iron Phosphate (LFP): The safest and most durable chemistry โ ideal for home installations with 6,000+ charge cycles
- Tesla Powerwall: Industry-leading integrated battery with built-in inverter, backup gateway, and seamless app control
- Hybrid Inverter + Battery: All-in-one solutions from brands like Sungrow, GoodWe, and Fronius that combine solar inverter and battery management
- AC-Coupled Systems: Retrofit batteries added to existing solar systems without replacing your current inverter
Benefits of Battery Storage
Adding a battery to your solar system unlocks a range of benefits that solar panels alone cannot provide:
- Maximise solar self-consumption: Use up to 90% of the solar energy you generate instead of exporting it cheaply
- Slash evening electricity costs: Power your home during expensive peak tariff periods using stored solar energy
- Backup power during outages: Keep essential circuits running when the grid goes down โ lights, fridge, internet, and more
- Energy independence: Dramatically reduce your reliance on the electricity grid and protect against rising energy prices
- Long lifespan: Quality batteries come with 10โ15 year warranties and are designed to last well beyond
- Increase property value: Homes with solar and battery systems command premium prices in the market
Ideal for Melbourne Homes
Melbourne's electricity prices are among the highest in Australia, and feed-in tariffs continue to drop โ making battery storage an increasingly smart investment. By storing your solar energy and using it during peak evening hours, you avoid the most expensive grid electricity and maximise the return on your solar panels.
Whether you already have solar panels or are planning a new solar installation, we design battery systems perfectly matched to your energy usage patterns and goals.
"Since adding a battery to our solar system, our electricity bill dropped from $400 to under $60 per quarter. We barely import anything from the grid now, and the backup power during last summer's storms was invaluable." โ James & Sarah T., Werribee
System Sizing & Recommendations
Recommended Battery Sizes
- Small household (1โ2 people): 5โ6 kWh battery โ covers evening usage with a modest solar system
- Medium household (3โ4 people): 10โ13 kWh battery โ ideal for most Melbourne families with 6.6kW+ solar
- Large household (5+ people): 15โ20 kWh battery or stacked modules โ for high consumption and full backup capability
- Off-grid or full backup: 20 kWh+ with hybrid inverter โ complete energy independence solution
Installation typically takes one day for a standard retrofit, or can be done simultaneously with a new solar installation. We handle all electrical work, metering updates, and grid connection paperwork.
