[RE-wrenches] HIQ Inverter Experience?

[Patrick Shortell]

Hi Chris,
My experience with microinverters rated NEMA 6 in a salt environment was an
absolute disaster. I have a 50KW ground mount, Enphase M210's, Sanyo 220's
and within three years more than half failed.
The system is approx a 1/2 mile from the Ocean and about 300 Yards from a
bay and is also on an island.
We removed the microinverters and installed SMA string inverters.
We have similiar installations in the immediate area and the SMA product
has held up for 12 years.
My microinverter experiment ended badly and as an electrician for over
thirty years, the enphase product was the only product I ever saw with a
NEMA 6 rating.
My Opinion, you cant beat an SMA product in this environment.
