[RE-wrenches] Expected Life of SW Inverters

[Nick Soleil]

I have installed a few SW-4024 in Hawaii, 1/4 mile inland.  Those units have had 
issues with Lizards, which required finer screens around all the openings and 
vents.  These units have been installed for about 9 years, and we have had to 
replace one of them twice.  We have seen some rusting and corrosion.

My SW4048 went through 3 boards from 98-04 until I retired it. Blowing salty air 
across a FET rail and mother board that is not conformal coated, created a 
perpetual triage environment.

Sealed units or units that pull air out vs blowing them directly on their boards 
in a coastal environment will increase the likelihood of a longer service life.

Alot of this experience birthed SMA's first generation inverters with the giant 
fins on the top, like my 2500 grid tied unit.

Heat, salt and varying voltage, amperage and watts flowing into these devices 
surely contributes to their longevity as well.

Friends:

Speaking of life expectancy, has anyone had experience with SW inverters in a 
coastal environment?
