Victron 10kva ,cerbox and blue nova battery.
Is there a way to get a signal output when my battery reaches a specific SOC.
Eg: When my battery reaches a 40% Soc then a signal could switch an external bulb * on*
I hope that makes sense of what I would like to do.
One way to do this is on the Cerbo GX, enable generator start / stop function on Relay 1, this can then be set so that it activates when the SOC falls below a configurable level and deactivates when it increases above another higher value. Then connect a positive supply to the relay and on to a bulb and then to negative. You will not need many of the generator functions, details in the manual.
There is probably an inverter assistant that could do this but I am not familiar with this.
You could also use Node Red to control the Cerbo GX relay.
As you have a Cerbo GX, if you have VRM set up you can set alarms on that which send emails or notifications to your phone.
Thanks will give it a try
