What happens in the case of removing a module permanently for whatever
reason? Is there a coupler to splice the home run wire, or do you have to
install a j-box?
Either way, I can see how leaving little slack in the home run wiring
could be a good idea.

I remember from a project we were doing that required Romex that it is
listed for damp locations such as outdoor areas likely to see some rain,
wet locations are literally underwater rated and designate conduits running
underground likely to flood.

The NEC 100 definition for a wet location includes unprotected
locations exposed to the weather. Obviously the roof is a wet location.
NEC 334.1(A) says NM cable is permitted in normally dry locations and
334.1(B) says it shall not be used in damp or wet locations. That said,

Next question: Should a 3R rated box like the SolaDeck, or an Outback or
Midnite combiner box, or even a bell-type box be used on a rooftop that
normally has snow on it in the winter?
Here's the NEMA description for various enclosure
Hi, Wrenchies~
I've been remiss in failing to send props to Larry Crutcher regarding his
clarification on how battery charge regulation really works. See his post
copied below. I see my error in that current is not directly reduced by the
charge device, but the controller pulses get shorter and
I agree that this list is *the bomb*.
I think back to the old days of PV, where arrays and gennys were either
mostly on or off, and the Absorb phase was mythicalbut really it is
the only thing that actually brings a battery bank to 100% SOC, and the
controller just lets it happen, rather than
6 matches
