Good decisions start with clear information.

Often, yes. The suitable approach depends on your existing inverter, solar system, switchboard and energy use. Share the inverter model and an electricity bill so we can discuss the options and whether any equipment changes are needed.

Only if the system is designed and configured for backup. Ask which circuits can operate, the available power and whether additional switching equipment is included. Battery size alone does not tell you how much of the home can run at once.

Kilowatts (kW) describe power: how much equipment can deliver at a moment in time. Kilowatt-hours (kWh) describe stored or consumed energy. Compare usable battery capacity as well as the power available to your chosen circuits.

Start with your evening and overnight consumption, available solar generation and future plans. An EV or electric hot-water system can change the calculation. A larger battery is not automatically the most useful or economical choice.

Joining a VPP is optional under the federal battery program, although eligible on-grid equipment must be VPP-capable. A separate VPP offer has its own contract and access conditions. See our rebate guide for official sources.
