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.

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. _____ From: William Miller <will...@millersolar.com> To: RE-wrenches <re-wrenches@lists.re-wrenches.org> Sent: Tue, November 2, 2010 6:51:11 PM Subject: Re: [RE-wrenches] Expected Life of SW Inverters Friends: Speaking of life expectancy, has anyone had experience with SW inverters in a coastal environment?
