Thomas,<br>
The SMA inverters do have the SMA combiners you mentioned(see
attached photo). As I said we have only done a walk through but we
did check the string VOC at one of the combiners. With all fuses
open string 1 +/- = 411 and the other string were the same. But
String 1 + to string 5 - also reads 411. It did not matter what
combination you tried they all read 411<br>
Just one more thing that needs to be diagnosed if they decide to
move forward.<br>
<br>
Thanks<br>

Hello Jon.<br>
Another thought??Was the site using the SMA combiner boxes with
the 3 SMA Tripower 15000TL-US -10?<br>
We have had ground faults occur there internally. If it has a
green test button inside the combiner box unit (polarity tester)
?. replace the combiner with a different manufactures equipment.<br>
I believe the model is called SMA 1000-US-11 String Combiner w/
Disconnect.<br>

Thanks Bryan,<br>

I do not know the PV connector types for the modules or
extension cables<br>
we have not started working on it. I need to put a plan together
for the<br>
customer first.<br>
Good to know about the Amphenol H4 issues.<br>

Do you recall which PV connectors were on the modules and what
they used for extension cables?<br>
<br>
Around that time, Amphenol H4 connectors had issues due to the
plastic housings failing and allowing water into the
connections.<br>

Subject: [RE-wrenches] Module snail trails<br>
<br>
Hello All,<br>
<br>
I have a local utility with a 50Kw array installed in 2015
consisting of 200 ReneSola 250w modules and 3 SMA Tripower
15000TL-US -10. They are having Arc fault code on two of the
inverters. This has been going on for a few years now. It
happens a couple times a year generally after a large rain.
They just reset the code and it comes back to life.<br>
<br>
They gave me a walk through and we noticed that a number of
modules have snail trails. I have attached a closeup picture I
took and IR views of affected module and non affected. It was
a 90 deg day when the utility took the IR pictures.<br>
<br>
Causes for snail trails that I found:<br>
<br>
* The difference in chemical properties of EVA foils and the
silver contacts<br>
* The degradation extent of the EVA material<br>
* Water vapor permeability of the solar panel?s backsheet
material<br>
<br>
I did find that if you have snail trails you will have micro
fractures. I did see some info that micro fractures could
cause arc faults.<br>
<br>
Finally my question is can snail trails cause arc faults also?<br>
<br>
<br>
Thanks Jon<br>

Looking at the pictures again, I wonder if there might be a
pinhole in the back lamination that is allowing water into the
module.<br>

<br>
Wrenches,<br>
We have a client that has brought utility power in and we now
have the system hooked up to the utility.<br>
In setting the system up, I've experienced that the inverter
will sell and function fine with all the settings set up as Grid
Tied mode, but it does not play nice when the grid is gone , and
the Generator is brought in as the AC source.<br>
We have installed an external transfer switch to switch the
inverters' AC input, from either the utility or the existing
backup generator ( if the grid fails), automatically.<br>
<br>
The manual states that the inverter's two input selections can
be programmed for seperate input modes, via the Input Type menu.
Ive not been able to get this accomplished.<br>
<br>
When simulating a grid outage, thus changing the AC input to the
inverter being from the Generator, the inverter will not synch
to the AC power to charge the batteries.<br>
The only way that I can get the inverter to synch, is to switch
the input mode to GEN from GRID.<br>
This is not ideal since the client would need to be present to
make the button push, even though the generator will be started
automatically if the grid were to go down (hopefully) , just as
it did before.<br>
<br>
With no way to contact Outback , can someone advise how to
properly program the inverter/ MATE3S for this project?<br>
Equipment onsite:<br>
Single VFXR3648 inverter<br>
Two FM60 CCs<br>
Hub4<br>
MATE3S<br>
ATS with Dual Relays 50A<br>
L.A. Battery bank<br>
<br>
Here's how we would like it to work:<br>
Utility power ON:<br>
Sell excess power once the batteries have gone through the
Absorb cycle. Batteries remain full in case of a utility
failure.<br>
Utility Outage:<br>
ATS now feeds Inv AC input via Generator if needed.<br>
Inverter runs the home as it did , off grid.<br>
If the battery voltage drops and the AGS is engaged, the
inverter will use that input to charge the batteries as usual.
If the grid comes back on and the gen is running, the generator
can still run, with no connection to the inverter. With the grid
now charging the battery bank, and the AGS will enventually shut
off the Gen. Based on voltage.<br>
Contact me off list if necessary<br>

Hi Jeremy,<br>
<br>
We have a client with 4 of the VFXR3648's in the same situation,
GTBB and you've described our solution perfectly although we
installed a manual transfer switch instead of the ATS, so if
someone has figured out a better solution we'd like to know what
it is, thanks.<br>
