SB Disco for 2 strings (was RE: ST XR series, anyone tried on yet? ) [RE-wr

[jberdner at sma-america.com]

Wrenches:

I was just at the MREA show with Chris and we discussed the CB at
length.
I'll try to jump in here with a "pretty well informed opinion".

The segmented breaker in the Outback box are Listed for two wires per
terminal.  Depending on the UL series fuse rating of the module, this
means you can use it for two sub arrays (depends on which inverter).
The negative terminal is a bit too small for two wires but they can put
in two blocks if you ask. 

I am pretty sure there is NOT enough room for 2 6 poles for the dc side
and a separate 2 pole for the AC side. They can do the 6 pole for the
DC, a 2 pole for the AC, and separate fuses in holders for multiple sub
arrays.
In this configuration you can't segment the array but it will still
serve as the 600 Vdc disconnect with individual fuses for each sub
array.

If you have any questions, or if I can be of any further assistance,
please do not hesitate to contact me.

Best Regards,

John Berdner
