Melbourne's Tesla Accredited Solar Battery Installer

A quality LFP battery should deliver 3,000 to 6,000 full charge-discharge cycles before capacity degrades to 80% of its original rating. For a household cycling the battery once per day, that represents 8 to 16 years of useful life before the battery needs replacement. Older NMC chemistry batteries typically deliver 1,000 to 2,000 cycles under the same conditions. This is why chemistry selection matters for long-term economics – a cheaper NMC battery may cost less upfront but deliver a worse cost-per-cycle outcome over time.

We supply and install battery products from manufacturers with proven Australian performance records, locally-based warranty support, and technology appropriate for Melbourne’s climate. Specific brands and models are recommended based on your system size, inverter compatibility, installation location, and budget. We confirm our current product range when preparing your quote. We do not carry every brand on the market – we carry the brands we are confident standing behind.

Yes. A battery-only installation – sometimes called a standalone battery or grid-connected battery storage – can charge from the grid on a time-of-use tariff and discharge during peak-rate periods. Without solar, the economics depend entirely on the spread between your off-peak charging rate and your peak import rate. In Victoria, where time-of-use tariff spreads are moderate, the financial case for battery-only installations is narrower than for solar-plus-battery. We model the specific financial case for your tariff before recommending battery-only installation.

A time-of-use tariff can improve the economics of battery storage by allowing you to charge from cheap off-peak grid electricity overnight and discharge during expensive peak periods – even without solar. If you also have solar, a time-of-use tariff combined with battery storage is typically the most financially optimal configuration. We model your specific tariff structure and consumption pattern to determine the best charge-discharge strategy before recommending a battery product.

True overnight self-sufficiency – covering 100% of your evening and overnight grid consumption from stored solar – requires a battery sized to your total after-dark load. For a typical Melbourne household with 4 to 6 people, this is typically 12 to 20 kWh of usable battery capacity. However, full overnight self-sufficiency is rarely the most cost-effective goal. A battery sized to cover 70-80% of your evening consumption typically delivers better cost-per-kWh economics. We calculate the right target for your household based on your actual data.

Only if the system is configured and installed for backup operation. Standard battery installations are grid-following – they shut down during a grid outage to comply with AS 4777 anti-islanding requirements. Backup-capable systems require automatic transfer switching equipment that isolates the home from the grid and allows the battery to power designated circuits independently. This must be designed and installed from the start – it cannot be easily retrofitted. If backup capability is a requirement, tell us when requesting a quote so we design for it correctly.
