    Bidirectional charging guide

    1. Below are questions based on your ownership of a solar PV and/or battery system and having a single-phase electrical arrangement at your home, or business premises (with a connection <=100 Amperes), followed by guidance around your options to connect a single-phase bidirectional charger:

      1 Does your premises have existing inverter capacity, i.e. solar PV and/or battery?

      Yes

      No

    2. 2 Will the combination of the existing PV inverter capacity and proposed bidirectional charger inverter capacity exceed 10kVA, e.g. PV inverter capacity >3kVA and charger inverter capacity >7kVA?

      Yes

      No

    3. 3 OK then. Does the premises have existing battery-only inverter capacity, i.e. not a hybrid inverter capable of serving PV and batteries?

      Yes

      No battery

      No, I have a hybrid inverter <=10kVA

    4. 4 OK then. Will the sum of the existing battery inverter capacity and planned bidirectional charger inverter capacity exceed 10kVA, e.g. battery inverter capacity >3kVA and charger inverter capacity >7kVA?

      Yes

      No
