Common questions about home battery storage in Perth.
It depends on your usage pattern. If you use most power in the evening, a battery stores your solar for when you need it. Modelled payback is typically 7-10 years with current WA rebates; actual results vary. If you're mostly home during the day, solar-only may be a better investment first. Use our calculator to compare both scenarios for your household.
Quality home batteries like Tesla Powerwall and BYD typically last 10-15 years and come with 10-year warranties. Most are rated for 6,000-10,000 cycles, which equates to daily cycling for 15-25 years.
Most Perth households need 10-15 kWh of battery capacity. This covers typical evening usage (5-8 kWh) plus some reserve. Larger homes or those with EVs may need 15-20+ kWh.
Yes! Batteries can be retrofitted to most existing solar systems. Some batteries require a compatible hybrid inverter, while others like Tesla Powerwall have built-in inverters.
Yes, but only if your system is configured for backup. Most installations include a backup gateway that disconnects from the grid during outages, allowing your battery to power essential circuits.
