Load profile
A time-of-day curve that distributes your daily kWh total across the 24-hour window. We multiply this shape by your “Daily load (kWh)” setting to get what the house uses in each step of the day.
How to choose
- Residential weekday / weekend — typical AU home load shapes with morning and evening peaks. Choose whichever matches the day(s) you’re modelling.
- Working from home — flatter midday load, useful for self-consumption modelling.
- Off-grid home / mobile — fridge-only baseline + evening lights / cooking peak.
Personalised profile (measured data)
When you have either a CSV upload (NEM12 / utility export) or a layout-linked inverter with at least 3 days of load history, the “Use my measured-data profile” dropdown above this one lets you replace the generic curve with one trained from your actual usage. In that case this Load profile dropdown is disabled — the measured profile overrides it.
See personalised load profile help for how the training works and what to do if the measured data won’t apply (e.g. too few training days).
When this matters
For grid-tied homes with a battery, the load shape matters as much as the daily total — a home with evening-peak usage needs the battery to hold charge through to sunset, while a home with daytime usage gets more self-consumption from the same solar. The right profile gives you a realistic forecast of imports, exports, and battery cycling.
