Residential.
Homes, estates and apartment blocks. Rooftop PV, behind-the-meter storage and a tariff structure that largely determines the project economics.
Load characteristics
Residential load is small, highly variable and diverse, so the aggregate load behaves very differently from that of an individual dwelling. The platform models both, because the optimal system for a single house differs from the optimal system for two hundred.
- Sharp evening peaks that set the storage size, while daily energy sets the PV size
- Diversity between dwellings; the aggregate peak is well below the sum of individual peaks
- Export limits and network hosting capacity that cap how much rooftop PV is useful
- Time-of-use and feed-in tariffs that dominate the payback calculation
- Shared infrastructure in apartment blocks: common-area load, embedded networks and metering arrangements
- Backup requirements, including the proportion of household load to be maintained during an outage and for what duration
Single household, live
A 10 kW rooftop array and a 13.5 kWh home battery on live Sydney weather, against a household load with a typical morning shoulder and a sharp evening peak. The battery supplies the evening load after PV generation has ceased.
Engine configuration for this application area
Standards and criteria applied
- Wiring rules for domestic and residential electrical installations
- PV array installation and DC-side safety
- Grid connection of inverter energy systems, including export limitation and inverter settings
- Battery energy storage installation, siting and safety separation for domestic premises
- Metering and embedded-network arrangements where a block is served collectively
The applicable set is confirmed at kick-off and depends on jurisdiction, connection point and the reliability target agreed with you.
