Hi Dave,
The Isc issue is true because the Evergreen is a 12v nominal module, so won't
work with the current version of the enphase anyway.

I also live in a area without much lightning, however I install one in most
systems for the simple reason of insurance.

Hi Ray,
Specialty concepts makes a sealed 48v unit that I'm trying to find who I can

vehicle and possibly get wet.
thx,

use a buck/boost transformer to bump it up the voltage.
This trick has the advantage that it doesn't have the hz be too high.
