I need to do a repair on this system, but cannot figure out what brand/type of mounting rack they have....ideas? I'll do a follow up post with a closer up pic of the top clamps.
anyone know what type of roof racking this is?

My advice, don't work on it until complete darkness. Opening an operating DC circuit could produce
an arc that will destroy the connectors, and the voltages on a series string system are quite dangerous.
Here the disconnects get opened and I break a string in 2 or 3 places plus its fuse, plugging the open
MC4s with some dummy sealed mates. Then I could work on it in the day, usually use lights instead.
good luck, Bruce Roe -

Looks like possibly Iron Ridge rails with some non-IronRidge lame bolts and way too small washer as a clamp. Hopefully, there is a copper wire bonding all the panels to ground...
The cable is an Enphase trunk cable that has AC power flowing not DC.BSEE, R11, NABCEP, Chevy BoltEV, >3000kW installedComment

Thanks Emartin! As soon as I read your post and reviewed your link, I remembered installing those racks for a bit back in 2012.Comment
