Uni-Solar laminates [RE-wrenches]

[matthew tritt]

Daryl and Marco again,

Just re-read your post Daryl, and thought I should clear up a couple of your
statements: The connections for the front mounted output wire format are not
done under the roof sheathing, they are made on the outside, under the
ridgecap. Also, if you are doing installs using SunnyBoys, the negative is
not bonded to ground on the DC side. If you did that, the inverter(s) would
probably see it as a ground fault and (at least) blow the inverter fuse.
