February 14, 2020 update

Hawaiian Electric and Enphase Energy, Inc are working on an upgrade agreement regarding the replacement of legacy inverters through Enphase’s Legacy Product Upgrade Program.

Subject to the terms and conditions of this agreement, Enphase’s IQ7PD inverter model will be allowed for use in one-for-one warranty replacements of legacy M-series and S-series inverters. These replacements will need to be reviewed by Hawaiian Electric by way of submission of a DER Amendment form (PDF). The technical requirements will need to be agreed to when the upgrade agreement is finalized.

In the interim, customers with executed interconnection agreements who have already purchased and/or installed Enphase IQ7PD inverters from Enphase will be given conditional approval to interconnect upon the submission of a properly completed DER Amendment form reflecting the use of Enphase’s IQ7PD inverters, which will (1) need to activate advanced inverter functions under Hawaiian Electric’s Source Requirement Document V1.1 standard, except for the Volt/Var function, and (2) be validated through the normal interconnection review processes. Please work with these customers to submit DER Amendment forms documenting the applicable equipment changes. If you have questions, please email us at
