Lightning strikes again? Morningstar TS 60
Yesterday there was a violent storm which passed through, major lightning, I was not at home so shutting down wasn't an option, but could see the storm move in from where I was 4Km to the south, was on a tractor so no chance of racing home. When I got home the smell of magic smoke filled the room where the controller, Morningstar TS 60, is located, can't say 100% if lightning was the cause but too coincidental to be anything else. The component(s) that vaporized appear th be the diode(s) nearest the solar input positive terminal, SPD didn't help and appears fine?, everything else in the system still functional, the controller was indicating over voltage shutdown, red/green Led's alternating, remote meter blank but still functional with replacement unit, had a spare on hand, so 30 minutes to get up and running. Last time the inverter got surged and falied, ironically a year ago, May 2017.
