    • all new and existing inverters are balanced across supply phases to Western Power’s requirement as outlined in the Network Integration Guidelines.
    • the setting for “sustained operation for voltage variations” does not exceed 258 V as per AS/NZS4777.2:2015 clause 7.5.2
    • this inverter system has been designed for a maximum voltage rise within the installation of less than 2% or 4.8 V as per AS/NZS 4777.1:2016.
  5. In commissioning equipment the User must verify that:
    • approved import/export metering is in place
