Since its launch, the Whispr, PowerPlus Energy’s quiet, intelligent, all-in-one home battery, has quickly become the go to choice for installers and homeowners alike. Designed and engineered in Australia, the Whispr combines simplicity, resilience, and performance in a sleek, stackable format that reduces install time and eliminates the complexity of traditional residential battery systems.

“The Whispr was designed to simplify energy storage without compromising on reliability or performance,” said Rick McKenzie, National Sales Manager at PowerPlus Energy. “Since launch, the response from the market has been incredible, people appreciate having a smart, robust solution that’s easy to install and even easier to live with.”

A Smarter Way to Store Energy
The Whispr was built to address the real-world challenges of energy storage. From blackout protection to smart power scheduling, its intelligent design eliminates many of the headaches typically associated with traditional systems. And as a Clean Energy Council (CEC) listed product, it’s fully eligible for relevant government rebates and subsidy programs, like the Cheaper Homes Batteries Program.

Key features include:

• 20ms transfer time for seamless backup
• Up to 30A load support for essential circuits
• Zero electrolytic capacitors: fewer failure points, longer lifespan
• Internal AC & DC breakers, generator input, and PV black start

• IP65-rated and ready for VPP participation

“We’ve removed the usual pain points, no external transfer switches, no separate inverters, no fan maintenance,” said Edwin Cotter, Lead Engineer at PowerPlus Energy. “It’s the kind of product that just works. Installers know what to expect, and homeowners can trust it to quietly do its job.”

Like all PowerPlus Energy products, the Whispr is supported by expert technical assistance from our Melbourne-based team. Designed, engineered, and manufactured in Australia, it reflects our commitment to delivering high-quality, locally made energy solutions.
