[RE-wrenches] Radian, Blue Planet and SMA 21 series AC coupled

[William Miller]

Friends:



We are setting up our first Blue Planet system.  It is AC coupled with an
SMA SB7-21 back-feeding a Radian 8048.    We followed all of the
recommended settings when commissioning.



The battery SOC is chronically stuck at 90% as displayed by the Blue Planet
BMU.

I think the problem is the grid sell setting is at 54 VDC.  Blue Planet
likes 55.2.  I’m going to change that setting this afternoon but due to
some mysterious Optics bug, I have to drive to the site to do so.



If anyone has any experience with this kind of setup and can offer any
advice, well I’d be mighty grateful.



Thanks in advance.
