I have been dealing with L1 Overload shut downs my system. It appears I am having voltage drops 103-107 range from standard 115 volts. I was trying to find out why and when the voltage from the shore power is dropping.
asked
Can I view and graph AC shore power voltage?
In VRM advanced you can view voltage amps and frequency in graph form. Do you have a GX?
Hello Alexander
Thank you for your response Yes I do have the GX will that graph the AC volts in? I’m trying to see at what point the the L1 overload comes on
Thanks
Are you using a victron Multiplus / Quatro or similar?
Simply go to the 'Advanced Tab' in VRM, click on the 'Widget' selector (three slider icon, top right) select your relevant VE.Bus device.
Select the data you want to graph (in your case it sounds like 'AC Input Voltage And Current'). Just click on it and you'll get a tick to indicate it's selected.
That's it you'll now have a graphical representation of the data from that point forward in VRM via a widget.
You can also insert an sdcard and take your Cerbo offline, the Cerbo will then log to the SDCard.
When your ready (e.g you've duplicated your fault / overload condition) you can use the Victron Connect app to convert the file on the SDCard into xls format and see all the data that would have been uploaded to VRM on a PC / laptop, create graphs and maybe more easily spot any pattern etc that maybe indicate what conditions create the fault condition.
Then when your ready put your cerbo back on line and it will sync all the data it collected when offline with your VRM installation so you also have everything there too.
I've included an example file so you have some idea of the data you can get (it'll be all your system connected device data, and detailed dates/times).

Thanks neptuenuk, that did. I have this long enough that I should have know. Thanks again. TC
