Backup performance depends on both kW and kWh, and in three-phase homes, per-phase inverter limits can be the weak link. Here’s how to design and operate battery backup that works when the grid fails.

Controlled-load hot water can sit outside a solar-and-battery system, despite accounting for around 30% of household energy use. Explore timers, contactors, changeover relays, and dynamic diverters.

SolarQuotes’ 2026 ACT and Tasmania awards used weighted customer reviews from a 12-month period, with a 15-review minimum. Summit + Shore Energy and Degree C Solar topped their regions.

Fox ESS Power Cube: 10.92-49.14 kWh storage, 5-12 kW single-phase, 63 A backup, IP66 and 200% PV oversizing, with three-phase coming soon. We unpack the specs, rebate thresholds and caveats.

AS/NZS 5139 recommends smoke alarms for rooms containing indoor battery systems, but local regulations may make them compulsory. We compare Australian requirements, smoke versus heat detection, and interconnection considerations.

At 28 kWh/100 km, an electric ute costs about $8.40/100 km on grid power, or under $1 on solar, versus $25.65 for a diesel at $2.85/L. The catches: towing range, payload limits and charger access.

Firmware 26.34 lets Powerwall control the Gen 3 Wall Connector directly, enabling Charge on Solar for any EV plus tariff- and forecast-based Low-Cost Charging. Here’s what changed for mixed-brand systems.

Tesla has two new updates for Australian owners, one for solar charging and one for powering devices from your car. Here are the catches.
