[RE-wrenches] Adding Charge Controller(s)

[jay peltz]

Hi Jeffe,

I don't know the specs on those Kyocera, but if they are the same VOC then they are fine together.

As to a enclosure for the CC's, I'd look at Midnight.
They have about a million different boxes, you'll find one that will do the job for you I'm sure.

Depending on the area, you might look at a midnight 150v, or  200v or 250v controller, as you can then run all in series.

There are fuses in the combiner boxes on the array, but no disconnects inside at the charge controller.  So adding 3 charge controllers, and now needing to add GFDI, means a box of some kind needs to be added to house these breakers.

It will of course allow for all the DC OCPD  and allow for the landing of the output of the charge controllers.  Or is there another enclosure/OCPD solution I should look at?
