We do lots of bigger systems and our inverter of choice has been SMA, we have seen many manufacturers either fail or be bought out, neither we have any control over but considering issues SMA has had the least of any. We have used fronius, AE, ABB, and satcon some filled with rain water, some just die, so far SMA has been good on all fronts with 15 tripower 24 k`s on line at one location all in the weather 100% on line, we have 50 k at the wetest locations there is and they work well there too.<br>
