[RE-wrenches] SMA DC Disconnect Switch failure

[Jerry Shafer]

Was the switch connected through the center tap bypassing the fuses or did
you use the combiner part using the fuses also.
How big was the inverter and how many modules and strings.
SMA makes different combiners depending on the inverter, you can tell by
the wire size.
