[RE-wrenches] Fronius IG4000 problem

[William Miller]

Bob-O:

Are you installing inverters outdoors near the ocean?  That seems to be the 
biggest issue, corrosion on the IG series circuit boards.  Fronius was 
touting their board coatings at the all day seminar, but now the plus 
series no longer has flow trough ventilation.
