[RE-wrenches] MLSD module level shutdown

[Solar Energy Solutions]

Dear All,
I have been an outspoken critic of module level shutdown for all the reasons folks do.  However, I have come around.  We have witnessed too many systems where rooftop wiring has been chewed up by critters... mostly squirrels.  We have seen everything from residential fires to holes in metal roofs caused by a DC arc.   I never thought I would see the day when I would not only be thinking MLSD is a good idea but advocating for it.

Smiles,

 So far the module level shutdown requirements have been a real blow to our industry. The reliability and cost from a maintenance and installation standpoint has been very hit or miss so far. It feels like this requirement was rolled out far too quickly without enough forethought to its impact on the industry. We are constantly going out and fixing problems with mlsd installed by other contractors. Thankfully the problems have nothing to do with the quality of the installations. The problems are almost all due to premature failure of the products or some inherent defect in them. This is a serious issue costing the industry time and resources and making our installers less safe. It just doesn’t really accomplish the intended goal of the requirement. 
I’m curious how other wrenches are dealing with this issue. I recently became aware of fixMLSD.com which appears to be focused on bringing a more sensible approach to this requirement. 

Your thoughts are appreciated,
Sky Sims
