When I've purchased shunts from AEE, they've been the "good " ones, 
solid base, they look like Deltecs.

That series of shunt is pretty cheap in small quantities. Less than $30.

Re: [RE-wrenches] Radian orders hardware problems

[Kienan Maxfield]

I have installed a whole lot of GSLCs and Radians. That is the primary product 
I've installed over the last 5 years. I have always purchased the Radian with 
the GSLC175-PV-120/240 which comes pre-wired with three shunts etc.

I have never had any problems with missing or broken/cracked parts but I have 
seen the wiring come loose in shipping. I saw one shunt that melted due to an 
under-torqued bolt.

I had a Flex-Net that was pre-wired wrong. That issue cost me an extra trip to 
the remote site at over 8 hours of drive time alone because the initial 
misdiagnosis was a faulty Flex-Net. That one took me a long time to diagnose 
because I was operating under the assumption that the factory wouldn't have 
wired it wrong. Of course, tech support never guessed that was the issue 
either. This was the one time that I felt like the manufacturer should have 
definitely compensated me for some of my costs... but I didn't figure that 
they'd go for that idea so I didn't ask.

I have had a lot of warranty issues with the earlier Radians and the old Mate 
3, but so far I've had really good luck recent Radians for off-grid use and 
with the new Mate 3s. The strangest issue I've had (and still have) with a 
Radian is that at one site, every once in a while, the grid-tied radian gets 
stuck in export mode and it'll drain the battery to somewhere around 85% or 
lower, sometimes exporting until 1 A.M. It is very infrequent and impossible to 
predict so that issue has never been solved.

Thanks,
Kienan

We mostly install 8048 inverters.  Regardless, you need all of the hardware for 
installing a 4048 or an 8048 and any GSLC.  Not having them is a huge headache 
and cost.  I can’t believe Outback is still letting this happen.



I would familiarize myself with what is needed and inventory as soon as the 
equipment is received.  Here is a partial list, from memory, and partial photo 
attached.  I can’t guarantee this list is complete, but it is a start.



1. 2 or 4 8 MM bolts and washers for Pos and Neg ports.

2. Remove and check shunt for cracks.

3. All Neg bus bar parts.  Includes two or three bars, 8mm nuts and washers 
(photo below).

4. All Pos bus bar parts.  Includes two or three bars, 8mm nuts and washers 
(photo below).

5. Flat plate with 10 holes for ganging inverter breakers (photo below).

6. Screws to mount breakers and FNDC to panels.

7. Dead-front screws.

8. Cover screws.



[cid:image004.jpg@01D48BC6.14159050]



Some of the above parts ship with the inverters, some with the GSLCs.

Re: [RE-wrenches] mate 3s locking

[William Miller]

Wrenches:



A few wrenches have inquired about the Control-by-Web system I created to
monitor Mates, routers and modems.  Here is a page

I created to outline the general concepts.



I hope this answers all of the questions.



I can share more details and possibly some Lua script on a case-by-case
basis if you contact me off-line.



William



PS:  The heart of the system is a dedicated 24 volt battery array left over
from a generator sync system.  The, CBW, router and modem all float on this
battery bank.  The draw is minimal and the cost of an outboard battery
array or one powered by a converter is justified by the increased
reliability inherent with a battery powered system.

Hi William,



I am interested in your control by web solution for the mate lock up.  Is
that a specific controller that does that or have you modified something?
Could it be used to reboot routers/modems as well?



Thanks

I have problems with all of my Mate3 and 3s controllers locking up.  So
much so that I have implemented the following steps:



1. For most installations I leave the hub wire cover off and label the
Mate lead.  Clients are instructed to unplug and re-plug the Cat5 lead
whenever the Mate locks up.

2. On one installation I have a Control By Web unit ping both Mate3
units every 5 minutes.  If either fails to respond after 3 attempts, a
relay opens and closes the Orange/white leads which power cycles the
Mates.



Locking up of Mates is a fact of life with Outback equipment.  I love the
equipment and I hate the equipment.

Hello All

And

Hello Jay

I just asked the tech support boss on this as I had no idea.

He has a test setup that allows him to switch individuals lines on the cat5
cables.

We can duplicate Jay’s  screen shot below by opening the some of the lines
to the cat 5 cable.



So as a start try replacing the cat5 between the Mate3S and the Hub.

Using the silicone grease that comes with a Mate is never a bad idea.

If your customer does not have a cable on hand I would try removing the
cable several times perhaps that could help to dislodge any corrosion or
dust on the connections.



I hope this helps.

Take Care All

HI All,



I’m wondering if anyone else is having mate 3s locking up problems?



I’ve got 2 systems that have had this happen.



One is a big system ( 2 radians and 5 CC).  Of course its a long ways away
and no there isn’t internet so no OpticsRE.



Its been reprogramed with latest REV firmware.  No change.

Wrenches:
 
I am reaching out to this group to see if anyone is having the problems we are. 
 At least 50% of the Radian inverters and/or GSLC cabinets we order arrive 
missing some part or piece required to install the inverter.  Sometimes it is 
one or more of the bus bars to connect the main DC breaker to the inverter, 
sometimes it is one of the 8mm nuts required on these bus bars, and the most 
recent order, and on our most recent order, one of the inverters was missing 
the 8mm bolts and washers required to connect the bus bars to the inverter plus 
and minus ports.
 
We have been having this problem for years.  Has anyone else experienced this, 
or is it just me?
 
Also, the shunts provided in the GSLC cabinets are crap.  It used to be the 
shunts had a solid base.  Now the bases are hollow.  We use to see these shunt 
bases cracked almost 100% of the time in shipping because the long, 
cantilevered negative bus bar was entirely supported at one end by the shunt.  
Any modest bump on the GSLC cabinet broke the shunt.  Now we receive them 
intact because Alpha has stopped installing the shunt prior to shipping.  The 
problem persists, however, because if you put the slightest pressure on the 
negative bus bar to align the holes to install the bolts (if they arrive), 
minimal strain in the base of the shunt cracks it.  See the photos below of the 
old versus new style shunt. 
 
Each of these problems slows down an install and creates frustration.  This 
persistent pattern is really not acceptable.
 
Lones, please investigate these problems and let us know if they can be 
rectified.  And please, send me a set of the 8mm bolts.
 
Thank you,

Grainger, Digi-Key, Mouser, the WWW, etc. The system I've ended up designing 
with what I have found is a kluge to just have a Morning Star Relay Driver 
disconnect the output of an inverter.. AC coupling 48 V inverters seems to 
always have the glitch of finding a relay. 

Catalogues will show these, but suppliers don't have them.

Re: [RE-wrenches] Radian orders hardware problems

[Michael Morningstar]

William,

I wish I didn’t know what you are talking about. I too have encountered missing 
parts and have dealt with the crappy shunt. I switched to purchasing pre-wired 
power centers built by a company in Mount Shasta. They will accommodate my 
requests for small deviations from standard layout. I’m curious how many 
problems with inverters and boards folks see. 2016-17 saw me swapping out a lot 
of components. One Radian was 1/2 DOA, and another lost an inverter after a 
week.

Re: [RE-wrenches] Radian orders hardware problems

[cwarfel]

I have only installed two so far on the small island I live on and had
none of these problems.  We have installed 4048's and I am wondering if
these problems are with 8048s or 4048s?  Thank you, Chris Warfel
