AlphaESS SMILE. All-in-one energy.

AlphaESS is a reliable, storage-focused battery brand for Australian homes and businesses. Founded in 2012, AlphaESS is an established storage specialist rather than a generalist, and its SMILE all-in-one systems are backed by local Australian service specialists and partners plus a large global fleet. The SMILE series uses long-life LFP (lithium iron phosphate) cells, a chemistry that is inherently safer, more thermally stable and longer-lasting than NMC alternatives, and it integrates a hybrid inverter and battery in a single unit to reduce components and simplify installation. Every SMILE system carries a 10-year warranty, and IP65-rated outdoor models are built to handle Australia's climate. Because AlphaESS concentrates on energy storage as its core business and Mission Green works with SAA-accredited installers to fit the SMILE range, it is a proven, well-supported choice for households and commercial sites wanting dependable battery backup and solar self-consumption.

Yes, the AlphaESS SMILE works with a Virtual Power Plant (VPP). AlphaESS SMILE systems are VPP-ready and support a wide range of mainstream VPP integrations available in Australia, so once your battery is enrolled you can earn from exporting stored energy back to the grid during periods of peak demand, when wholesale prices and network signals are highest. A VPP effectively pools many home batteries so a provider can dispatch stored energy when the grid needs it, and you share in the value that creates. Alongside VPP participation, the SMILE series provides UPS-style backup power that keeps your essential circuits running during a grid outage, switching over quickly so you stay powered through blackouts and storms. The AlphaESS app keeps you in control of how your stored energy is used, letting you balance self-consumption, backup readiness and VPP earnings to suit your household.

Yes, you can scale an AlphaESS system from a single home right through to commercial sites. The SMILE M and SMILE G3 series are modular for residential needs: SMILE M is a single-phase all-in-one that stacks in parallel for roughly 5-30kWh, while SMILE G3 offers single and three-phase hybrid systems with built-in inverter and backup, including rebate-friendly 14kWh and 28kWh tiers popular with Australian families. For larger requirements, the StaX commercial range stacks plug-and-play modules from 30-50kW output, scaling well beyond 100kWh for businesses and high-demand sites. Across the SMILE series the overall capacity range spans roughly 5-200+ kWh. Because the design is modular, you can start with a smaller capacity now and add matching modules later as your energy needs grow, without replacing the equipment you already own, which makes AlphaESS a flexible, future-proofed choice.
