[RE-wrenches] Help understanding 690.12/Ul 3741 and Ironridge

[Zeke Yewdall]

My understanding of UL3741 is that you need to have the racking system, the
shutoff units (often string level shutdown units), and the inverter all
listed to work with each other.  So far, I have been unable to find any
combination that does what I need (specifically, any battery based
inverters other than Tesla that are listed with shutdown units and
racking), so I've still been using module level shutdown.  ul3741.com has
lists of what is cross listed with what else.
