to you and all the others for the speedy replies. We installed one single
Radian and I will never again buy a pre-wired GSLC. The wiring was sloppy
and it is unrealistic to try and cram the AC and DC switching into one or two of
these cabinets. </FONT></SPAN></DIV>

more frequently we forego using the standard BOS AC Cabinets for AC distribution
and instead go directly into standard outboard AC cabinets. This is true
for FX, SW, MX and Radian installations. Here's how we used to do this

been designing and building our own bypass interlock brackets. With some
aluminum stock, a band saw and a little ingenuity we have been able to build any
interlock we need. For this installation we will back-feed the generator
into an extra breaker in the inverter-fed panel We will interlock it with
the two inverter fed breakers and have a very reliable and inexpensive
bypass. I am fixing to do an article on my web site featuring the various
interlock solutions we have built.</FONT></SPAN></DIV>

off the subject, but one can use a single phase panel to handle the output

<DIV dir=ltr align=left><SPAN class=160444221-05082013><FONT face=Arial>I am
curious about why you would recommend the Petametric. It handles only
three shunts just like the FNDC. I understand you can install an unlimited
number of charge controllers to the FNDC (and maybe the Pentametric as well) as
long as you shunt the combined negatives with any shunt having the correct
amps/mv ratio. The FNDC integrates with the Mate 3 which seems desirable
to me over the Pentametric. Comments?</FONT></SPAN></DIV>

<P class=MsoNormal><SPAN
style="FONT-FAMILY: 'Calibri','sans-serif'; COLOR: #1f497d; FONT-SIZE: 11pt">We
have installed one dual Radian system. We looked at the prewired distribution
boxes from OutBack (MidNite’s wasn’t out yet at that time) but they had no
bypass solution for two inverters. We ended up using an external 100 A, 2 pole,
double throw safety switch for an AC bypass from the generator feed, a little
spendy but the only thing we could come up with. The newer MidNite E-Panel
Master & Slave setup deals with the bypass, I haven’t gone through to price
it out to see if it makes sense yet, but I bet it does, especially since you can
use dinrail breakers instead of all panel mount, as is the case with
OutBack.<o:p></o:p></SPAN></P>

<P class=MsoNormal><SPAN
style="FONT-FAMILY: 'Calibri','sans-serif'; COLOR: #1f497d; FONT-SIZE: 11pt">Not
sure if you like or are planning on using the FlexNet DC, but on our install we
had two inverters and two charge controllers, so the otherwise convenient
triple-shunt-busbar option (OutBack) didn’t really do much for us. Kinda dumb
you can’t use two FlexNet DCs… When I do it again I would probably steer the
customer towards a Pentametric.<o:p></o:p></SPAN></P>

<P class=MsoNormal><SPAN
style="FONT-FAMILY: 'Calibri','sans-serif'; COLOR: #1f497d; FONT-SIZE: 11pt">Ditto
to the comments on the firmware upgrade and spacing the inverters. Next time I
will definitely use a few nipples between the distribution boxes, the doors are
way too tight when spaced right next to each other.<o:p></o:p></SPAN></P>
