[RE-wrenches] SMA Sunny Island Repair.

[Jim Duncan]

Several years ago I had to replace a 8 year old SI due to a simple 
shorted main DC disconnect. SMA sent a refurbished unit which lasted 
another 5 years or so. Just within the last year I replaced both with 
new units. The other original one circa 2007 SI was not compatible with 
the new ones so both were replaced. As for repairs I don't do 3rd party 
repairs, customers typically see the value in a new or refurbished 
inverter.
