      "q": "Where does the Andersen A3 cable go?",
      "a": "The A3's 5.5 m tethered cable is stored inside the housing when not in use. Andersen calls this hidden charging cable technology."
    },
    {
      "q": "Can the Andersen A3 charge from solar?",
      "a": "Andersen lists the A3 as solar compatible. Its installer manual describes a basic solar mode that uses the supplied grid CT clamp, and an advanced solar mode that needs an additional solar CT clamp. In the Andersen app you can set how much grid power to add to solar."
    },
    {
      "q": "Does the Andersen A3 need an earth rod?",
      "a": "Andersen says the A3 has no earth rod requirement. The installer manual lists PEN fault detection conforming to BS 7671 regulation 722.411.4.1."
    },
    {
      "q": "Does the Andersen A3 work with Intelligent Octopus Go?",
      "a": "Yes. Octopus lists the Andersen A3 as supported for Intelligent Octopus Go, and OVO lists Andersen for Charge Anytime (both checked 4 October 2026). Andersen says all A3 chargers have been integrated with Intelligent Octopus Go since September 2025."
    },
    {
      "q": "What warranty does the Andersen A3 have?",
      "a": "Seven years of Andersen Care Cover following installation, subject to Andersen's warranty terms."
    },
    {
      "q": "Which chargers are similar to the Andersen A3?",
      "a": "Andersen Quartz, Cord Zero and Hypervolt Home 3 Pro share the most charger types with it (such as solar charging, cable type and smart tariff listings). They are listed by how many types they share, then A to Z; this is not a ranking. Compare any two side by side on our compare page."
    },
    {
      "q": "Does the Andersen A3 support V2H or V2G?",
      "a": "No. Andersen does not publish vehicle-to-home (V2H) or vehicle-to-grid (V2G) support for the Andersen A3, so it charges the car only."
    },
    {
      "q": "How much does the Andersen A3 cost?",
      "a": "We do not list prices, because they change often and most people buy a charger fitted, so the price depends on the installer and your home. Ask two or three installers for a fitted price for the Andersen A3 by name. If you rent, or own a flat with private off-street parking, the EV chargepoint grant can cover 75% of the cost of buying and installing a chargepoint, up to £500."
