[RE-wrenches] Tying XW MPPT-80 controller into XW PDP

[Glenn Burt]

Even though that use is not a listed method for using that disconnect?
In order to be in compliance with its listing for use up to 600VDC, you have
to run a string through two blades in a disco.

I use the 3 phase 600vdc  disco from SquareD. It does have a fuse kit but I
try to keep 2 strings max on each mppt-80-600 to avoid fuses. With that
disco you could have 3 mppts. Use one inside the building and one outside.
There is a picture on my picture link on my webpage.
