AlphaESS batteries are engineered for high performance, safety, and flexibility, making them ideal for solar households that want lower bills, backup power during outages, and smart energy management.

    Why AlphaESS is a great choice

    Modular &
    Scalable Storage

    AlphaESS systems let you start with the capacity you need today, and expand up to ~60–80 kWh as your energy needs grow — perfect for homes planning EV charging, higher night-time use, or future electrification.

    Robust
    & Safe

    Using Lithium Iron Phosphate (LiFePO₄) chemistry with IP65 weatherproofing, AlphaESS systems are safe, long-lasting, and suited to Australian climate conditions.

    Smart Monitoring
    & Control

    Use the AlphaCloud app to view generation, storage, and consumption in real time — optimise charging for time-of-use tariffs and reduce grid import costs.

    Built-In Backup
    & Resilience

    With backup capability and fast switchover protection (UPS-style), AlphaESS batteries help keep your essential circuits running when the grid goes down.

    Save with Government Rebates
    in NSW & Federal Programs

    From 1 July 2025, eligible solar battery systems installed with solar can attract a Federal upfront rebate worth roughly 30% of eligible battery capacity — potentially reducing your installed cost by thousands of dollars.

    AlphaESS batteries

    • CEC-Approved for the Federal rebate
    • VPP-Ready for grid-interactive programs
    • Installed by accredited providers like Soltech Solutions

    This means a 10 kWh AlphaESS battery could attract around $1,860+ in rebate value in 2025 — and more for larger systems.

    Your battery could earn
    up to $1,500 more

    While direct NSW standalone battery rebates have changed, many households with eligible systems can still earn additional VPP payments — often up to $1,500+ — by participating in grid support programs.

    Step 1

    Connect your
    AlphaESS battery to an
    approved VPP provider

    Your battery securely connects to a Virtual Power Plant provider, linking your home to the wider energy network.

    Step 2

    Receive regular incentives
    for supporting the grid
    during peak demand

    During peak demand, your battery shares stored energy with the grid, helping keep the lights on for everyone.

    This further lowers your cost of ownership and increases lifetime value.

    Have any questions?

    We’ve got answers.

    Solar panels generate electricity during the day. If your home doesn’t use all of that energy, the excess is stored in the solar battery instead of being sent to the grid. You can then use that stored energy later — such as in the evening or on cloudy days — reducing the amount of electricity you need to buy from the grid.
