    What this does and doesn't tell you

    • Compare the payback with the warranty years.
    • Rebates, VPP payments and backup value aren't included.
    • Safety: in Australia, any work on 240V AC wiring, including connecting an inverter, battery or solar system to a home's switchboard or fixed wiring, must be done by a licensed electrician.
