Thanks a lot for your answer, Coulomb

Hello everybody, my first post, so first I want to thank all of you for all the valuable information and advice you share on this forum. I have recently started running an offgrid system with Axpert King I and I would need some advice, I do not want to create a separate thread so I am posting my questions here as it seem a general thread about this model. At the moment I would appreciate your advice on the two issues below: 1. I accidentally shorted the battery +/- terminals on my spare Axpert King I shorty after it was turned off and the battery was disconnected. As the capacitors were charged, there was a popping noise and a spark/arc for a brief moment, as the capacitors discharged. I connected the battery again (through a bulb to avoid too high a current) and the inverted started up and seemed working normally. Could I cause any damage by shorting the terminals? 2. Strange intermittent static noise/clicks coming from the inverter at random intervals, usually once in a few minutes, it is similar to the sound of static discharge or relay clicking - but it is at stable load, no system mode changes, so it is not a relay, the inverter is new and working normally. Have any of you had a similar experience? Is it normal or something to worry about? I have come across a few people reporting this on another forum, but generally it is not something frequently reported. I found that somebody posted the same issue on Youtube, you could hear the noise here Thanks for your help in advance!
