I will try to explain one of the times when I choose to use the male cable. The site had 28 modules on one roof, but due to fire access walkways, and limited space, we had to place on module on a different roof. The main array was on a roof with skylights that broke up the rows of modules, so our Enphase strings travelled along the peak of the roof, then down to a lower row, then back up to the row by the peak (with a gap in the top row.) The end of that 8 module sub-circuit was located across the hip, and 15' from a single module that did not fit on the main roof. So at the end of the 8 modules we wanted a male cable, so that we could tie the end of the string into a
j-box, transition to 3/4" conduit and then run to the other roof, where we could use a female whip to pick up the single module. We did not want to have to run 40' of conduit and wire for the one module, which would have had to jog down to the middle row and back up to stay under the modules, and would have had to cross rails. The other option would have been to use an extension cable (assuming that the 15' cable was long enough), but that would have required a 1-1/4" emt chase between the roofs to fit the extension cable end. With bends in the conduit, we question if we would even need a 1-1/2" chase. We decided to cut the extension ends, and transition to conduit in between.<br> Essentially, this was just an extension cable, with 3/4" conduit and 2 j-boxes in the middle of it. I guess you could argue that we never need just a male cable, because we will always need a female on the other end. That
is why I am not really complaining about the lack of male cable options, because the Enphase extension cable is a good solution. <br><div> </div>Nick Soleil<br>Project Manager<br>Advanced Alternative Energy Solutions, LLC<br>PO Box 657<br>Petaluma, CA 94953<br>Cell: 707-321-2937<br>Office: 707-789-9537<br>Fax: 707-769-9037<div><br></div><div style="font-family: arial,helvetica,sans-serif; font-size: 12pt;"><br><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><font face="Tahoma" size="2"><hr size="1"><b><span style="font-weight: bold;">From:</span></b> Kent Osterberg <kent@coveoregon.com><br><b><span style="font-weight: bold;">To:</span></b> RE-wrenches <re-wrenches@lists.re-wrenches.org><br><b><span style="font-weight: bold;">Sent:</span></b> Fri, January 21, 2011 11:20:18 AM<br><b><span style="font-weight: bold;">Subject:</span></b> Re: [RE-wrenches] EnPhase male whips<br></font><br>

Could you post a diagram showing when a male whip is useful? I'm
having a really hard time envisioning a need for one.<br>

Your diagram is one way to do it, in fact, I always divide my
circuits into 2 sub-circuits, to minimize voltage drop on the Enphase
wiring, and then parallel the sub-circuits at the j-box. However,
there is a value to having a male cable. They can simplify some
installations, such as the situation that Eric described. As mentioned
before, the extension cable can be cut, and the other end is used as a
standard whip.<br>

You connect the factory provided termination kit to the Enphase array
on
each roof. All of the Enphase inverters on one array do not need to
be in a daisy configuration.<br>
<br>
I have attached a drawing hat should illustrate<br>

its a funny title but....why
doesn't EnPhase make whips with male connectors? We are having trouble
laying out a system with multiple sub arrays. We need to cable to sub
arrays that are on different roof planes in order to make up our
circuits. From 5 micros on roof one, into attic, out of SolaDeck on
roof
two, grab 3 more micros, back into SolaDeck, into attic for home run.
The
whip from the SolDeck to the last 3 micros needs to be male... any
suggestions? EnPhase does not want us to cut an extension that has
connectors on both ends...<br>
