Features

Why choose
AlphaESS.

All-in-One Design

The SMILE series integrates a hybrid inverter and LFP battery in a single unit. Fewer components, a cleaner install and a tidy footprint for the garage, laundry or an outside wall.

LFP Chemistry

Lithium Iron Phosphate (LFP) cells are inherently safer, longer-lasting and more thermally stable than NMC alternatives. Built for Australia's climate with IP65-rated outdoor models.

VPP-Ready Income

AlphaESS supports a wide range of mainstream VPP integrations in Australia. Earn from exporting stored energy during peak demand while the app keeps you in control.

Backup Power

Built-in UPS-style backup keeps essential circuits running when the grid goes down, with fast switchover so you stay powered through outages and storms.

Modular & Scalable

Start small and add modules as your needs grow — no full replacement required. SMILE scales for homes; the StaX range stacks to commercial-grade capacity.

Established Specialist

AlphaESS has focused on energy storage since 2012, backed by local Australian service specialists and partners. A storage-first brand, not a generalist.
