[RE-wrenches] Expected Life of SW Inverters

[Dana]

My SW's in Costa Rica had geckos that crawled in to the
circuit boards and died[fried] & as they desiccated they
turn acidic and that really did a number on the circ.
boards.

The salty  environment also did in all aluminum parts and
the interior had a white crust on everything.

 

In the salt environments use a marine & sealed - coated
unit. It is worth it in the long run. Treat it like a boat
on a beach if you want it to work long term.

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?
