Adelaide Hills Residence

Adelaide Hills, SA · 13.5 kWh battery + 10 kW solar

Adelaide Hills home with rooftop solar panels and battery storage

The challenge

The household experienced several unplanned outages each summer due to fire-season network shutdowns and ageing rural infrastructure. Existing solar was undersized for the home's evening load, and the owners wanted assurance that essential circuits, lighting, refrigeration, water pumping, would stay live during an extended blackout.

The approach

Esena's assessment started with an interval-data review of twelve months of grid consumption, followed by a site inspection to confirm roof orientation, shading from surrounding tree cover, and switchboard capacity for a backup circuit.

The recommended system paired a 10 kW solar array with a 13.5 kWh battery configured for backup-critical circuits, sized against the home's typical overnight and outage-period load rather than a generic capacity target.

Installation included a dedicated backup panel isolating essential circuits, so the household retains power to key loads even if the broader system reaches its storage limit during a multi-day outage.

Indicative outcome

Project profile, indicative figures based on comparable Adelaide Hills residential installations. Individual results vary and are subject to site assessment.

Comparable households in this configuration typically see the majority of daytime consumption met directly from solar, with the battery covering evening and early-morning use before falling back to the grid. Backup coverage for essential circuits during an outage is generally sized to last through an overnight event, with actual duration dependent on household load at the time.
