William, This is new for the 2017 code: 2017 NEC 690.13(D) An equipment disconnecting means shall simultaneously disconnect all current carrying conductors that are not solidly grounded. Yet Schneider, Outback, Midnite, Magnum, and ... all still have a single PV wire disconnected at the charge

[RE-wrenches] Experiences working with SMA SBS 6.0 battery inverters

Hello Wrenches, I would like to hear from anyone who has had recent experiences dealing with installation and tech support of SMA-America SBS 6.0 battery inverters, ABU's etc. We have done three installs this year and would like to discuss the installation and follow ups with SMA tech support. Than

Re: [RE-wrenches] Floatovoltaics

Hi Corey, Yep I have seen them up in Napa on a small lake. It seems very risky in the Caribbean. The only thing I want on a roof is gutters for rainwater. You can tell I am biased. Maybe someone else has better info. Dave Angelini Offgrid Solar "we go where powerlines don't" http://members.s

Re: [RE-wrenches] White wire for DC- after ground fault breaker

It also seems like there should be some sort of wire marking to indicate functional grounding.  This code change makes sense, but it unleashes many new questions as well.  My vote is that is that PV is already current limited, so I don't see good reason to add fusing to the "functionally ground

Re: [RE-wrenches] White wire for DC- after ground fault breaker

Wrenches: Well now that the NFPA has acknowledged that GFDI protected circuits do not solidly ground the “grounded“ conductor, and we know they can’t be white in color, it begs the next question: Should these sort-of-grounded grounded conductors be switched and over-current protected? The

Re: [RE-wrenches] Floatovoltaics

Hi Dave, I was actually referring to a growing trend in the PV industry (particularly in Asia) to attach PV arrays - and also inverters in some cases - to floating pontoons and then install them on bodies of water. The systems are often referred to as floating PV (FPV) or "floatovoltaics". Here's

Re: [RE-wrenches] White wire for DC- after ground fault breaker

James, where is the CT located? If it’s in a panelboard/loadcenter, I understand that they are not “certified” to allow CT’s inside so the work-around is to pass the conductors thru a jbox before the panelboard and locate the CTs there. Benn Kilburn SkyFire Energy 780-906-7807 > On Jun 14
