Multiplus 48/3000 not switching on

hi guys…today after using my easysolar for 7 years…it went off. Checked No over-heating, no short-circuits…it couldnt start again. Using VEflash, I upgraded the firmware to 2620552…no change. It makes a continuous clicking sound, unable to connect to AC POWER line in. Victron connect app can see it and change settings. Help

hi guys. Posting a follow up of my easysolar
I sent the inverter to the authorised Victron dealer for analysis and possible repair. The technicians told me the control board wasn’t accepting any firmware and couldn’t be fixed. I doubted the info as I could load firmware via VEflash and Victron connect. I asked them to return the inverter and at the same time bought a new hybrid inverter(Deye 5kva single phase). after I received the ‘dead’ inverter, I reconnected the cables to test as I wasn’t over it and voila, the inverter booted without any issues. Now it is working perfectly well leaving me both surprised by its sudden resurrection and sadden because I had shelled out 1100usd for the new hybrid inverter. Any idea what happened?
