What are you using for bus bars for systems in excess of 48 volts DC?
48 VDC max seems to be the magic number where companies like BlueSea cap out their lower amperage busbars.
For my situation, I want to build a combiner box where each string of panels could be pushing 66 VDC.
I had got Gang Box connectors rated at 60 amps, 600Volts and 8 AWG wire before. I could use this again, but am looking for something smaller. I used these in my last combiner box I built:
I would like to use something like these from midnite solar, but they give an amp rating of 180 amps, which is plenty, but mention nothing of votlage. Its pretty common to list max amps, but have not seen a max volts even for the some type of product listed by other companies.
