Questions

How is the federal rebate worked out?

The Cheaper Home Batteries Program pays small-scale technology certificates (STCs). A battery gets 6.8 certificates per kWh of usable capacity for the first 14 kWh, 60% of that from 14 to 28 kWh, and 15% from 28 to 50 kWh. The factor drops to 5.7 on 1 January 2027, so the same battery gets less after that date. The date on the battery's electrical safety certificate decides which factor applies, not the date you sign a contract. Your installer claims the certificates and takes their value off the price. The government clearing house pays $40 per certificate before GST, which is why each figure says "up to": certificates also trade on a market, usually for less. Rules checked 28 September 2026.

How is the rebate chart drawn?

The lines give the federal rebate at every half kWh of usable capacity, taking nominal capacity as equal to usable. The dots and the table use each configuration's own capacities from the approved list, so a dot can sit slightly off the line.

Which states add their own rebate?

Western Australia pays Synergy customers $130 per kWh of usable capacity up to $1,300, and Horizon Power customers $380 per kWh up to $3,800, if the battery joins an eligible virtual power plant. New South Wales pays certificates for joining a virtual power plant, which your VPP provider buys at its own price, so no dollar figure is shown. South Australia has a virtual power plant offer for concession holders whose amounts we could not confirm from an official source, so it is not shown. Victoria, Queensland, Tasmania, the ACT and the Northern Territory have no household battery rebate open.

When does the rebate reminder arrive?

About a month before each drop in the federal rebate, starting with 1 January 2027: one email with what the rebate is worth before and after. You stay signed up for the next drop, and every email has a one-click unsubscribe.

What happens when a battery's approval ends?

A battery gets the federal rebate only if its model is on the Clean Energy Regulator's approved list when it is installed. Installed after its approval ends, it gets no rebate, even if you bought it before. A model can be approved again later, so ask your installer before you sign.

Which configurations are listed?

Every SolaX Power T-BAT-SYS-HV-S3.6 configuration on the Clean Energy Regulator's approved battery list whose approval hasn't expired. A battery must be on the list to get the rebate. Usable capacity is the figure on the list, not the model name.
