High-Demand / Whole-Home Backup is a residential building-planning choice in the Price Your Build estimator. Solar and backup use cases set the expected load coverage, battery capacity, inverter design and electrical integration.
What this option means
Solar and backup use cases set the expected load coverage, battery capacity, inverter design and electrical integration.
Why it affects the estimate
The estimator uses this selection to establish an early allowance. Final cost depends on the approved drawings, site conditions, supplier system, installation method and contractor scope.
Before proceeding
Confirm the appliance load schedule, essential circuits, roof space, distribution board changes and installer design.
Compare the final specification, exclusions and installation detail against supplier and contractor quotations.
Confirm the relevant professional, municipal and product requirements for the actual project.
Use the estimator
