Phil, Do you find that the DC optimizer adds to the amount of time on an install?
Thanks, Will From: RE-wrenches [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of Phil Forest Sent: Tuesday, May 20, 2014 1:26 PM To: RE-wrenches Subject: Re: [RE-wrenches] 2014 NEC Will, No problems with inspectors for us in MA, regarding rapid shutdown, since we recently switched to using SolarEdge central inverters with optimizer under each module, for roof mounted installs. So far so good. They seem well made and engineered. Tip: you have to enable the arc fault protection when commissioning, ships disabled.

In Mass we’re having all kinds of issues with inspectors requiring/allowing an array of different things for 690.12 rapid shut down ranging from roof top disconnects, disconnects on the side of a house 20’ up, disconnects in attics, or only disconnects that can be activated on the ground. It varies between inspectors. We’re also having problems with one inspector requiring arc fault breakers on Enphase even though there are no UL listed arc fault breakers that can be back fed or he wants us to run the trunk cable in a raceway. It’s getting very difficult to install in Mass.
