Hi Patrick I would add that the NEMA 6 rating is for dust/water intrusion, not corrosion resistance.
I don’t know what the metallurgy of the Enphase was/is or the HIQ. But I would not make the assumption that whats bad/good for one is the same for any other. jay Peltz power > On Mar 11, 2016, at 9:29 AM, Patrick Shortell <pshorte...@gmail.com> wrote: > > Hi Chris, > My experience with microinverters rated NEMA 6 in a salt environment was an > absolute disaster.
