[RE-wrenches] SMA SB........ -41 sources, connection box cover

[Bill P. Battagin]

Jay, 

I was told by the owner and the maintenance person that there was an event where some snow that had built up on the lines, had let go during a melt and sprung up to contact other lines above. We've seen every possible type of snow here in the mid-elevation Sierras, it must have been some weird conditions that even allowed the snow to adhere to the lines in the first place......and then continue to build on that? I don't know more detail than that but PG&E is accepting responsibility for the event.

Hi bill. 

I’m just wondering how did you confirm pg&E did the surge? 
I’d like to know for my own education 

Thx

Fellow SMA Lovers, 

I have an installation that has 10, SMA SB-1SP-US -40 and -41's PG&E thought it would be a good idea to send a surge into the service of this install so 3 off the inverters were compromised. 

1) I've gone to Ebay for replacements sometimes as SMA would not consider this a warranty issue. Anybody have a source for new or refurbished other than Ebay? 

2) Also it would be good to know, can the bottom connection box covers with displays be swapped/interchanged between different inverters and between -40 and -41 versions? 

Thanks as always, 
Bill
