Jay:
The back story is sometimes useful. Thank you for filling in the details.
I have a soft spot for community radio. I also have some used, working SB 2500U
inverters on the shelf. I’d be happy to send you one. Contact me off list.
The used inverter offered came from an art-house theater.
Dear wrenches
I did not include the back story as it is not relevant to my inquiry. However
given the comments I decided to include it in that it will hopefully clear up
any confusion.
Where I used to live, the local community radio station ( poorly funded) has a
old PV system with you guesse
Wrenches
I would also be surprised if the old 2500 would last very long.
Better off with a SB5.0-41 and if you need RSD then add that in also.

"IEEE 1547-1" certification is required at least in the New England ISO
document which our utilities abide by. IEEE 1547 does not qualify. My local
utility denied my approval for installation last year of a old SMA2500U
inverter for this reason.

Yes, these should only be used to get a grandfathered system back up and running(no ARC fault just GFDI) or a off-gridder that is not going to have any concerns...Oh, and back when we were doing these at SMA in the test area we had a "special" rom set that made this conversion from 240 to 208v easy
Hi William,
Years ago we were buying ferrules and ferrule crimpers to deal with the
extra fine stranded conductors coming with microinverter trunk cabling at
the time. I think it was PowerOne / ABB. Anyway, if that's the type of
ferrules you need, we got them from ferrulesdirect.com.

William,
I have used various brands of both ferrules and crimp tools. Most of the
ferrules I have used are German-made by the Weidmuller brand, these seem to be
private labeled by Greenlee and others. Highly recommended. I’ve also had good
luck with less expensive ferrules sold through various
Friends:
Do any of you have a preferred make, model and supplier of ferrule crimps
and crimp tool you would recommend?
Thanks in advance,

Probably if it is old it does not have these recent Certifications and
UL requirements. Just gave these to my local AHJ.

I would think the existing LPS, if as extensive as you suggest, would need to
have its interconnections removed, and the LPS installer contracted to
re-evaluate and re-install an LPS that also integrates the new array into its
protection scheme.
I am assuming this is a commercial rooftop instal
Hi Kirk,
Can you elaborate on which UL standards the older SB units don’t comply with?

Dave,
An Alternate solution might be to find two good used VFX3524's. All
circuit boards are available from Zonna if they need repair. I have one if
you could find another somewhere.
Contact me off list if interested.

These older Sunnyboys do not comply with latest UL standards regardless. If its
a new installation, a savvy utility / AHJ will catch this.
