We’ve installed many Midnite BHs with the disconnecting combiners (and battery disco modules pre 2017 NEC.) Recently we set up a roof mounted array with the disconnecting HV combiner along with the SOB for the PV Side of the CC. Worked well. I’d be interested in the OB gear as well. Jeremy

I think you would make a huge mistake to not use an all Outback or Schneider system! No mixing because the web portals are excellent from a monitoring sense. Much of my income is from monitoring so as they say, I'm a fan! Dave Angelini Offgrid Solar "we go where powerlines don't"

Ray, Do you feel that these are different from the microfractures or snail trails that were  reported widely across the industry a couple of years ago? Glenn Sent from my 'smart' phone so please excuse spelling and typos. -- Original message--From: RayDate: Tue, Aug 14, 2018 10:24 AMTo:

I am changing out an off-grid AC coupled SMA SB3000TL inverter tied to a dual stack VFX3648 system with a Mate (original - not Mate3) and an FNDC, making into a DC coupled array. It was set up as AC coupled originally because of the distance the array was from the system (about 500 feet) and high

Hi All; Its time to beat this poor dead horse again:  What is the latest, greatest ways to comply with 690.12 for lower voltage 150 Voc array with a charge controller in an off grid system?  At the moment, we are planning on using Midnite's new SOB system, and were told that while it won't

My cohort here that used to make PV modules thinks that something may have hit the back of the module ?  Maybe somebody weed-eating around the array and something hit it ? We notice the cracks in Ray's cells are white. Are the backs of these modules white too ? Interesting if they still

I had a module engineer tell me these are often a static discharge issue which happens during the lamination process. It’s not effecting the cell surface but the encapsulate above it. It’s not cracking but it looks like it. Jay Peltz power. > On Aug 14, 2018, at 7:31 AM, Dave Tedeyan

Ray, I just saw the same sort of thing on 2-year-old Peimar modules. In my case, there were visible hot spots that had burned through the backsheet in several places on several modules. In some places it was just small blisters, in others there was a clearly melted area of the backsheet. The
