: Grid-Tie Stumper (SMA Data Logging) [RE-wrenches]

[Jeff Clearwater]

<x-flowed>
Hey Kent,

KWHR total is what is need for this temporary situation of looking at 
a problem for the last two months.   Is there that much data in a SB 
inverter that can be retrieved if it's important like in Mo's 
situation?  How far back does KWHr data get stored in the inverter? 
There must be some built-in defaults on logging intervals, right?

I noticed when my Sunny Data Control was accidently turned off for a 
couple of weeks that when we turned it on the inverters downloaded 
the KWhr data so I know there is that much.

thanks,

Jeff C.

>>Mo/Jeff, yes you can do this with the SMA service cable and the Sunny
