Your solar panels generate electricity and power your home first.
Any surplus energy is automatically stored in the battery.
When solar generation stops, your home draws electricity from the battery instead of the grid.
If the battery becomes fully charged, additional solar energy can still be exported to the grid.
If the battery becomes depleted, your home draws electricity from the grid seamlessly.
Get control of your energy with residential battery storage systems - designed for Melbourne homes. Read on to learn how solar batteries work, the difference between AC and DC coupling, and how to size your system correctly to reduce bills and provide reliable backup power.
Many Melbourne households are considering installing home battery storage systems to store excess solar energy and use it when electricity prices are highest. With solar panels, paired with a solar battery system, homeowners are experiencing increased self-consumption, reduced reliance on the grid, and improved protection against rising electricity costs.
How does solar battery installation work? How to size a battery correctly? When does battery storage in Melbourne make sense financially? We often come across these and more such questions when it comes to residential battery storage.
A home battery storage system stores unused electricity generated by your solar panels during the day so it can be used later.
In a residential solar setup, a battery
● Stores excess solar energy
● Supplies power when solar panels aren’t producing
● Works alongside the electricity grid
Without battery storage, surplus solar electricity is exported to the grid at relatively low feed-in tariffs. On the other hand, with a solar battery system, you can use more of that energy within your home, which would help you reduce your energy bills.
Are you considering a battery addition to your system?
If you already have solar or are planning a new installation, we can assess whether battery storage installation will be the right option for your home!
Our team can assess your system and recommend the most efficient upgrade pathway for solar battery installation. Learn more about adding a battery to an existing solar system.
Not all home battery storage systems automatically provide blackout protection.
Standard Grid-Connected Systems: Most solar systems shut down during outages unless backup capability is installed.
Partial Backup: Supports essential circuits such as lighting, refrigeration and internet. Whole-Home Backup: Larger systems can power the entire home depending on battery capacity and inverter capability.
Backup Capability Requirements
● Backup-ready inverter
● Dedicated backup circuits
● Switchboard configuration
Backup functionality should be designed during solar battery installation. Need backup power for your home? Get on a call with a specialist at Enelex for a home battery backup system tailored to essential loads or full-home coverage!
The financial value of home battery storage in Melbourne depends on your electricity usage patterns and tariff structure.
Feed-In Tariffs vs Self-Consumption
Victorian feed-in tariffs are significantly lower than retail electricity rates. Using stored solar energy often provides better long-term value than exporting it.
When Do Batteries Make Financial Sense?
● High evening electricity use
● Time-of-use tariffs
● High electricity bills
● Long-term home ownership
● Energy security goals
When Batteries May Not Be Ideal?
● Very low electricity consumption
● Mostly daytime energy usage
● Short-term property ownership
A professional assessment helps determine whether solar battery installation in Melbourne is financially worthwhile.
Choosing the right configuration depends on whether you are installing a new solar system or retrofitting battery storage.
AC-Coupled Battery Systems
● Connect to an existing solar inverter
● Ideal for adding battery storage to an existing system
● Slightly lower efficiency due to additional energy conversion
DC-Coupled Battery Systems
● Solar panels and battery share a hybrid inverter
● Higher efficiency with fewer energy conversions
● Common in new solar and battery installations
Battery capacity is measured in kilowatt-hours (kWh) - the amount of energy a battery can store.
Cycle Life: Most lithium batteries are rated for 6,000–10,000 charge cycles.
Battery Degradation: Battery capacity gradually decreases over time. Most reputable systems retain 70–80% capacity after 10 years.
Warranty Standards: Most manufacturers provide a 10-year performance warranty.
However, warranty terms may vary depending on throughput limits, cycle guarantees, and minimum retained capacity. Choosing quality equipment and accredited installation ensures long-term reliability.
