Jeff,
I just went through this. The SI and the US 40s still work together.
They do not use a 485 card. The Sunny Boys are programmed in off grid
mode, and the Sunny Islands take care of the UL1741 requirements.
Tim at SMA gave me this information. The Sunny Boys will taper charge
as shown on the graph below.
I called to ask about the 5.0 and 6.0, so you might want to check to
be certain about other models.

All,
Can anyone confirm for me that the SUNNY BOY 3.0-US / 3.8-US /
5.0-US / 6.0-US / 7.0-US / 7.7-US series is or is not supported by
the Sunny Island in off-grid AC coupling mode? The technical paper
on the subject here
<http://files.sma.de/dl/7910/SB-OffGrid-TI-US-en-18.pdf>http://files.sma.de/dl/7910/SB-OffGrid-TI-US-en-18.pdf
does not list them but I'm hoping it's cause that paper is dated Feb '16.
I sure hope they are because that paper shows they discontinued
support the the SUNNY BOY 3000TL-US / 3800TL-US / 4000TL-US /
5000TL-US / 6000TL-US / 7000TL-US / 7700TL-US series! Why!??
Hope you have good news for me!
Best,
Jeff
