Title: Doubled down on FX's..
Post by: TomW on May 20, 2013, 03:07:05 PM
After about 10 years using an Outback FX2524T as a supplement to our grid power we decided to double our capacity to feed loads.

2 FX2524T's 2 Epanels and 2 Classic 150's one for the 1500 watt solar array and one for the 12 foot turbine. and an OB PSX-240 autotransformer:

Installed myself with massive internet help from Ryan and boB at Midnite. Not the most elegant looking system but works and is paid for.

Now we don't have to do the math to see if we can run X, Y and Z together like before.

Still need to neaten up a bit and reconfigure wiring for 240 AC to the house. Our well is on the RE system now. We could easily get by if the grid went away!

Just a share.

Looks fairly ordered with the symmetrical E panels, Classics and inverters. No Clipper there  :)
Are those two small boxes lower centre fuses or breakers to the battery bank(s)?

Dgd;

Thanks for the comments.
Lower center "box" is a dual terminal block with the cover not installed. The breakers for batteries are not in the photo. The clipper is mounted out of the photo, also.

My wall space is limited in that room because of windows, door and cabinets. It was built as an office for my workshop in the garage and ended up being the most convenient (spelled close to the driveway) spot to put the 1300+ AH of traction batteries..

The RE system grew in place over 10 plus years. That is why there are so many holes in that wall the inverters are mounted to.

Tom, I cant see the RTS wires.  Where did you run them?
And what is that long black thing, above and in the middle, with the green wires?

West;

The temp sensor wires are artfully hidden among the conduits for the solar feeds to the Classic.  8) Only use one for Classics. None installed for the FX's as they only kick into charge mode in rare instances just enough to keep the batteries happy..

The green box is the Outback HUB4 that handles communication with the Mate and inverters.

The Mate is mounted remotely so not visible in the photo. There are wires in the photo that are unused remnants of prior configurations

Hi Tom,
I was wondering if you have had firmware problems when you needed to stack these two, old and new units, also did you stack it in serie/parallel? Did you have any issue with your old mate to set the system?
I'd like to add a new vfx3648 to my old one for a 7.2kw 120/240V output on an old FW500.

Erik;

I set them up like explained here:


http://pics.ww.com/v/TomW/Renewables/Clipper/Stacking.png.html (http://pics.ww.com/v/TomW/Renewables/Clipper/Stacking.png.html)

Schematic:
(http://pics.ww.com/d/491353-2/Stacking.png)

So far no firmware issues I know of.

The older FX has been rebuilt with replacement boards twice due to sky sparks and the last time only a year or so ago so I think it is relatively "current" compared to its original commissioning date.

The Mate seems to be doing the job fine. It was swapped out a couple years ago for a factory fresh unit after one of the sky spark incidents just to be sure. It is version 4.1.6 0x244F. Mate2 I believe

I have a herd of MNSPD's in the system now so I hope we avoid the static induced failures now.

It generally runs on the Master providing all loads 120 and 240 VAC and when demand gets above a KW or so the Slave kicks on and supports the load until it goes away for a minute or two. Works great and I am not convinced I actually need the PSX-240 in the system but it probably saves idle power not having to run the Slave all the time. Our submersible 240 VAC pump seems to run fine off one unless other loads are active and put it above a KW.

FYI the older FX is the Master in my configuration.

Good Luck with it.

No worries. Shtuff happens.

Glad to help any way I can.

There is no problem stacking old and new outback inverters, it is however prudent to set the newer one as master. I have a 2003 model stacked with a 2009 model.

DB;

Any particular reason? Or just "seems better"?

I have no clue how to determine firmware version on an FX. Do you know how? Just be nice to know, I guess.

Thanks.

Outback told me the newer firmware has more features and is more stable. Your rebuilt one will have the newer firmware.

Hi all,
I was also planning to set the new one as master to save on the old one as slave. I have the old black oval mate and I afraid of the cost of a refreshed unit to Canada, maybe better to buy a new one. Tom, in my message (that you'll never read  :)), I was talking about a storm we had two days ago, a strike hit very close to the lodge and I was sure the system was burned (my wife saw a ball of fire between the cabins!). I ran and switch all components off, MN-SPD were still blinking on every strike! After a while I re-started the system, ME-RC was blank and Classic had rebooted but was still alive, when I switched the system and loads on, the Magnum was still working!
I had already burned two VFX in the same conditions with delta LA 3 days ago.

Great to know that there are no problems to stack old and new one.
Is there a way to update the old one without shipping it to Outback or do we have to re-board to have the last version?
Thanks
Erik

Outback will send you a complete board set for the VFX for $460, it replaces everything but the transformer. It takes under an hour to do, under 15 minutes after you have done it a few times. Just call tech support and tell them you need a board set.

Erik;

In case you did not know, you can replace the board set quite easily with boards from Outback. They even have a good set of youtube videos showing the complete process.  Just open it up and swap the boards. Leaves only the case and transformer original.

Not sure which board has the firmware on it but they will do an out of warranty full board swap for relatively cheap. Was around $500 my last set. They get more $$ up front but refund it when you return the old boards.Not sure if it would be worthwhile to swap for updated firmware?

I see DB beat me in on the post but here it is anyway..

The firmware is on the "control" board

Tom,
I know, I did it two times and at the end... bought a Magnum and keep the VFX as spare, don't want to stay without electricity for three weeks.
I agree with you as I'm not sure that it would be worthwhile, I will mount it as it is and check first how dual VFX work.
Always good to learn from others experience.
Thanks DB for the info, I'll know which board to change, just in case I'd need it.

Not dealing with split phase, what size is the transformer, and do you have issues with balance across the 2 phases ??

I do have split phase so all I can tell you is this snippet from the manual:

The X-240 can also be installed as an isolation transformer with a rating of 2000 watts

I was assured it can handle more than my system can produce the way I have it installed. It never actually sees the full load as I have it.It is rated 6KVA according to Outback. You can see the specs on their website product pages.

The PSX-240 which is the transformer in a case with terminal blocks and breakers.  It seems to balance loads perfectly and it can start our 240 VAC submersible well pump (from a single 120 VAC inverter)  without kicking on the slave inverter unless other substantial loads are present. It runs 2 freezers a fridge, a satellite TV receiver and Christmas tree light night lites 24/7 so it seldom has "no load" and the Mate thinks it has a 100 watt load always.

The PSX-240 has become noisey under certain heavy loads over time. I contacted Outback Tech Support via email a couple weeks ago about it but they must not read their email. Guess I will have to call them to get some input on what may be the cause of it.

Happy with it so far and hope the noise is a simple thing like a loose screw not vibrating windings that could lead to failure. Time will tell.

Hope that helps

Tom
