Inverter stopped working this morning

[njka]

Hi all. I have a Victron Multiplus inverter model 12/2000/80 installed in a motorhome. It has been working fine for the that 10 months. However, the inverter won‘t switch on this morning. When swiched on via the physical switch on the inverter all three lights on the front flash together approximatly every 7 seconds. On the CerboGX the inverter constantly appears breifly then disapears in the device list.

I have replaced the rj45 cable to the cerbogx with the same results. Checked all the cables are tight. Tested the 12v power in and all is ok. (lithium battery working fine).Have turned the device off for at least 5min before turning back on.

The inverter was latst used yesterday evening to power a small hand food mixer.
Currently in Morroco with limited resources. Is there anything that can be done to fix the issue.
TIA

Hi @njka,

Multi doesn’t need the cerbo to work. If you have it, you should probably try to connect to the multi with a MK3 and a computer to see if there is anything you can do. Also, just to be on the safe side, you could try to disconnect all the loads on multi, and try another battery, like the one on your vehicle for example.

Last but not least, rtfm you’ll probably find out some out something I guess with the blinking sequence.

Ok, I think it‘s back up and running. I disconnected the positive terminal for a minute or so and it cleared the LED‘s on the Multiplus. Would still like to know what the flashing LED‘s mean if anyone knows, as they are not listed in the manual.
