Yes Mark,
Enphase sets the alternate grid parameters for HI remotely, and will send a
letter of confirmation directly to the utility on your behalf. We have
preset grid parameters for HECO and MECO.

Take it from someone in the trenches out here in the Aloha Stateyes, we
have to jump through these hoops. The utilities here-HECO, MECO, HELCO and
KIUC-vary as far as what they require regarding verification and
documentation. It's been my experience that HECO and MECO are more lax

We had the same request in NC by Duke Energy. The inverter mfg. says they can
do it but it'd be outside of the values on the label that the inverter is
