  • Does anybody have experience with the new Hawaiian Electric GTI requirements?

    I was just browsing the Fronius Primo data online and noticed a section on meeting HI Elec's new requirements.

    These apparently include:
    1. Setting the inverter to source current with a fixed non-unity power factor (apparently either to make PFC requirement for POCO less costly or to increase system stability when a high percentage of generation comes from residential PV.
    2. Setting the inverter, once it has qualified the grid power, to ride through for a specified time any sort term frequency or voltage excursions of the grid outside what UL requires for anti-islanding. With different higher tolerances still applying, I think.
    Also apparently to try to increase system stability when operating next to its performance limits. Any short term grid upset will not cascade into a catastrophic upset by taking all of the PV instantly offline at once. If the grid goes away completely normal anti-islanding still applies.

    Is this already being enforced for new installations?
    What other inverters can meet the new requirements?
