How the systems actually work, how they're sized to your usage, what the leading brands do differently, what rebates apply in South Australia — and how a VPP can pay you back.
Use this as a rough starting point. Every recommendation we make is checked against your actual bills, roof orientation and future plans (EV, pool, heat pump).

| Large / all-electric home | 30–45 kWh/day | 13.2 kW | 16–24 kWh |
| Home + EV + pool | 45–65 kWh/day | 13.2+ kW | 20–30 kWh |

These prices are accessible to households and businesses through Amber's VPP offering.
This is an example of how live wholesale market data can support smarter battery and energy decisions. Amber gives customers access to live wholesale electricity prices instead of a fixed feed-in tariff, with battery automation through SmartShift.
VPP and automation benefits depend on retailer availability, battery compatibility, network approval and the final system configuration. Bond Energy Solutions can recommend suitable hardware and explain whether Amber-style wholesale optimisation is appropriate for your site.
