\"Home<\/p>\n

The Cheaper Home Batteries Program is still booming, but long waits for installation are persisting \u2014 and it\u2019s not because of battery stock shortages. Installers tell SolarQuotes the main bottleneck is having enough accredited workers to fit them. Inspections and approvals play a smaller role; the real limiter is installer capacity.<\/p>\n

How Long Is The Wait For Home Batteries?<\/h2>\n

There’s been a surge of customers seeking to get a battery ahead of May changes to the federal battery rebate. According to the latest Sunwiz data, a record 1.2 gigawatt-hours of home batteries were registered through the Cheaper Home Batteries Program in February. Most reputable installers are now booked out until well into May, with new customers set to wait two months or more.<\/p>\n

Installers Are Reporting Long Waits<\/h2>\n

Graeme Galletly, General Manager at Goliath Solar & Electrical<\/a>, says his team is booked well into May 2026:<\/p>\n

\u201cWe have 8\u201310 weeks lead time \u2014 we\u2019re currently booking installations into May. Installation capacity is the main constraint. We\u2019re comfortable with our own team, but inspections and service work also factor into timing.\u201d<\/p><\/blockquote>\n

In Queensland, Caleb Davey from Expert Electrical<\/a> reports a similar story:<\/p>\n

\u201cWe\u2019re fully booked through to mid\/late May. Our main constraint is installer capacity \u2014 we\u2019d love to hire another qualified electrician, but finding the right person is tough.\u201d<\/p><\/blockquote>\n

Another installer told SolarQuotes that stock isn\u2019t an issue, and customers seem more patient than before Christmas, highlighting that workforce capacity is the central constraint rather than product supply.<\/p>\n

Stock and Brand Availability Are OK<\/h2>\n

According to installers, battery supply is not a limiting factor and popular brands are generally available.<\/p>\n

\u201cWe haven\u2019t seen supply issues with Tesla,<\/a>\u00a0Sigenergy<\/a>, Fronius<\/a>\u00a0or BYD<\/a>,\u201d says Galletly.<\/p><\/blockquote>\n

A recent development \u2014 Supply Partners Group securing a new distribution deal<\/a> for Tesla Powerwalls in Australia \u2014 should help keep stock flowing for one of the most sought-after batteries, with Powerwall 3 soon to be compatible with Powerwall 2.<\/a><\/p>\n

Why Installer Capacity Is the Bottleneck<\/h2>\n

Installer capacity is constrained by accreditation requirements and practical limits:<\/p>\n
