[RE-wrenches] SMA Micro-grid

[William Miller]

Friends:



I am working on an AC coupled SMA system in an off-grid setting.  We have
an SB4000-12 that was disconnected for a number of years and we reconnected
it.  The inverter is stuck in the waiting mode and  will not generate
power.  The Sunny Islands and Sunny Boys are connected via an RS485
communication system.



I suspect there is a programming step I have not yet accomplished.  I
recall some years ago I programmed the other Sunny Boys for off-grid
operation.  I can’t find anything in any of the manuals about how to check
the programming.  I also suspect SAM tech support talked me through this
and the information may not be published.



Does this ring a bell with any of you?  Any advice?



Thanks in advance.
