I have a quick tech related question.
I am trying to determine if my current combiner box to charge controller wire run is appropriately sized for a proposed PV expansion. My current run of #6 AWG ANCOR Boat Cable with (105 degree C insulation), technically can carry higher current than typical #6 AWG (rated at 60 degrees C). However that seems to be dependent on IF the terminal connectors in a) my Midnite combiner box and b) my FM80 are also rated at a higher temperature than the usual 60 degree C connector.
So my question for Midnite is, what are the termination ratings for the pre-wired Midnite combiners (I have the MNPV4). Are they 60 degrees C or 75 degrees C rated, or something different??
This technical bulletin from Cooper Bussman explains exactly what I am referring to:http://www.cooperindustries.com/content
ps. I've asked Outback a similar question.
