I have a grid-connected system with a battery (Multiplus II, Cerbo-GX). It works perfectly. Now I would like to receive a message or signal when the grid fails and my system is running in island mode. Is this possible and how can I implement it?
@Thomas_Keel You can set up alarms with email and /or push notifications in VRM.
Do you have internet connection when the grid fails
Yes Internet is available.
So the correct criteria is “Active input AC”?
Yes. You can see the exact parameter to select under the VE.Bus heading in the image.
so like this?
I’m not shure that this is what i want. My system is most of the time disconnected, as PV and Batterie can meet the demand.
I want a message when grid is not available and could not support.
My system is an ESS, 6000kms away to be exact, so every time there is a grid failure and the AC disconnects, it sends a notice and cancels the alarm when the grid returns. There are other parameters and devices to consider like L1 voltage etc. so best you experiment to find one that works for you.
On Node Red, there is an email node node-red-node-email
Enabling this will show up on the console, but not message you. Works without internet, but will serve you best if you have a monitor.
ok, thank you. I will try some things.
