[RE-wrenches] Adding Charge Controller(s)

[Jesse Dahl]

Jay ,

The modules have different electrical specs... 

I'd like to use the midnight because the new array in series is at 148V. We see -40F.  He already has the Outback 60 on site. That's why with 2 existing outback products I figure the Flexware route would work best. 

Thanks!

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?
