Reasons for Multiplus Powerpack Failure

Hi all


Recently had a Multiplus 48V / 5000 with a powerpack failure. (indicated by the LED sequence). Unit was used in an off-grid application. No Grid connection. Roughly 5 years old.

Replaced the core and the unit works perfectly again.


I would just like to get your views on what might have caused the Powerpack failure. Overload? , Surge? , age?


Thank you.


Kind regards.

there could be a lot of reasons I would think, here are some I have thought of

Lighting strike (I had one this week picture below)

EMP from a close by lighting strike

High DC ripple a lot of the time

Dirt, especially conductive dirt.
Condensation
High ambient temperatures, which compound the dirt issues due to the fans drawing in more air.
