Will do the sig.  Looks like most of the ones in the combiners are the newer 150Vdc designation anyway.  They have a confusing 125V sticker still on the side but the visible ends have the EMI 150Vdc sticker.  Looks like they are the newer ver.  This gives me another 25V to work with out there so I think the batteries will be the cold weather limit rather than anything else.  These AGM batteries aren't rated to accept charge below -10C, if I remember correctly, and I worked this all out last year when I built the bank, but they will discharge at that temp & below, however, though I don't think it happened last winter.  The inverter is rated down to -20C.  The panels are rated down to -40C and so are the breakers (at 150Vdc with this configuration).  Yes, there are some big panel mount breakers, (one is the 250Amp protecting my 0000 AwG battery + to inverter) in the power center that are likely 125Vdc.

QuoteIN 20 YEARS TIME FROM NOW , WE MIGHT HAVE 72vDC OR 96vDC iNVERTER from Midnite B19 !!

:D  I hope to be on here asking about configuring in a couple Classic 300s.   ;)
