[RE-wrenches] Swapping vintage SMA inverter to SB-40?

[Bill Battagin]

Wrenches,

             Earlier post was accidental, incomplete (below). Anyway,  
I've since rec'd a response from SMA (Thanks Mike), despite my lack of 
details of this proposed change-out he offered some valuable tips.

             Yes, I was hoping by splitting this array of 30, Evergreen 
190's into two strings, using 2 of the three MPPT inputs in the SMA 
SB-40 and using the existing wiring which is: "Diesel Locomotive Cable" 
yes, see the picture, leads from the PVs and USE-2 for home runs (in 
conduit), that this would work.

             A couple times I've taken the gamble of purchasing used 
not-to-old inverters off Ebay but as time goes on I'm feeling like my 
luck so far won't hold out.  Sometimes you can find an old inverter that 
doesn't many KWhrs on it and was mounted inside or north side of the 
house with a cooler climate....It depends on the customer and 
situation.  This seems like a solid way to go but would appreciate (+) 
or (-) feedback, experience.

             I wish I'd stocked up on SB-40's and 41's before they 
disappeared.
