Kelly: I see one problem: the inverter on the roof. Makes servicing and replacement a real pain.

I think it is the first inverter made to sit freestanding on a commercial roof. It looks like it has some super interesting features, including “String Failure Detection”. (Why is this feature deactivated by default?) I’m not sure how well it will satisfy the rapid shutdown requirement when the roof array areas are broken up, but on one with a contiguous array area, it looks like it’ll work for the 2014 NEC. Any bugs or issues I should know about? Thanks in advanced for your replies!
