[RE-wrenches] retail price lists

[jay peltz]

Anybody know the logic on why some manufacturers don't publish a retail price 
list?
For example, Outback?

thx,

jay

Re: [RE-wrenches] RS 232/tristar

[Glenn Burt]

Hi Jay,

I doubt anyone could say 'all' would work, but I have successfully used one
from I/O Gear on the TriStar.
A couple of weeks ago I taught a SITN class and we came up with three others
out of a box that once we found the right Windows drivers online, worked
fine with the SunSaver MPPT controllers. I suspect the same protocol is in
use in both controllers.

Good Luck!

Hi All,

Any special issues with using a RS232 to USB for programing the Tristar?

IE will any USB/RS232 adapter do?

thanks in advance,

jay

Re: [RE-wrenches] Dual Radian install

[Nathan Stumpff]

Re: FNDC vs. Pentametric, well now that you pose the question, it probably 
really boils down to personal preference and experience. I have installed a big 
pile of Pentametrics and it has been easy and they have worked really well, and 
my few experiences with the FNDC have been messy, although not through any 
fault of the equipment or OutBack. The FNDC just didn't work the way I thought 
it should, and it serves me right for not reading the manual more closely 
BEFORE I installed the thing.

I have always liked the 'fuel gauge' effect of the Pentametric display unit, 
which we typically put out where the customer will walk by it often. I guess 
some people put the MATE3 remote from the inverter room, but I would personally 
probably not ever recommend this. Also, I suppose the LAN/www connection 
options could serve this purpose well, but I don't have as much experience with 
it yet. I don't know, the online connections and monitoring are fun and novel 
for a bit, but I imagine people lose interest pretty quickly. I think having a 
box on the wall that gives you a snapshot into your battery bank's life every 
time you walk by has a lot of value.

Plus IMHO Bogart is just an awesome company. Not necessarily the most 
compelling reasons in the big picture...

Would be very much interested in info on some of your custom bypass solutions!

Nathan:

Thanks 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.

More and 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 
with SW inverters:  
http://millersolar.com/MillerSolar/Portfolio/Inverters/battery_iinverters/full_size_photos/3_input_sw.JPG

We have 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.

(This is off the subject, but one can use a single phase panel to handle the 
output distribution for a 120 only inverter system as well as provide a bypass. 
 One bus is inverter fed and the other is gen fed.  Properly configured 
breakers with an interlock provide the bypass capabilities.)

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?

Again, thanks to everyone.

William

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.

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.

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.

Cheers,
-Nathan

I am bidding installation of two Radian inverters. Anyone out there done this 
yet?  Got any advice?

Thanks in advance,

Re: [RE-wrenches] Dual Radian install

[matt]

William,

We recently finished a quad system.  Having familiarity with Outback, I am
confident you will find little trouble with these inverters.  We did
purchase Outback pre-wired cabinets.  Two minor issues with the install:

1) Regardless of what manual says, space inverters apart - especially if
you are using cabinets and want a functional cover.

2) Be prepared to do a firmware update (they have a Youtube video about
this process).

Good luck,

Matt
