I have a Multiplus 12/3000/120 that I have used for about a month. In the Victron Connect app and VRM, the inverter turns off right away, but then gives a 1 -5 minute delay in turning on. It always does turn on eventually. I am using the V.E. Bus Smart Dongle. I spent the last year using a 24/3000 and it turned on and off immediately. Now that I have gone back to 12volt, all I've done is rewire batteries and swap out inverters. Same dongle, same network in use. Nobody so far had heard of this, so I thought I would try here. Can anyone help? I can post proof, but it's a boring video.
