question

Did you get an answer to this? Am having the same issue!

Same question here.

I'd like to use this setting as well. When I'm not using the EV-charger the default setting for Self consumption from battery should be "All system loads" only when the ev-charger is turned on I would like to switch to "Only critical loads".

Bump. Same question.

Am now on Cerbo GX v3.30 and @victronenergy/node-red-contrib-victron v1.5.15 and still can't find it

Hello, I am new here. My setup has been powered on few days ago...

+1 for this topic, I having the exact same need with EV charger in manual mode (mostly at night) and should not be powered by 48V battery. I would like to be able to disable automatically the self consuption mode when EV starts charging the car.

Hope it will come soon!

i'm also looking for this option in node red

Hello everyone,

I have tried something: Did only two trial, but it seems to be working (at least if EV power measurement is not too wrong // EV conversion factor topic...)

Basically, I take EV power measurement and report it to the grid setpoint so DC battery of the victron system is not drained to the EV. Update rate @30sec, looks enough to me.

Conditions (can be tweaked in the "EV auto grid setpoint" function) :

- works in schedule or manual mode (not in auto mode then).

- Default grid setpoint is 0W

- if DC battery SOC is > 90%, use grid + 3200W of solar energy (random number, didn't search for available solar energy measure info if any...)

- if DC battery SOC < 90% , use grid only

- if using solar energy and SOC drops down < 90%, move to full grid and wait for SOC > 92% to come back to mix grid + solar

Note 1 : tested with multiplusII in ESS mode.

Note 2 : It's my first Node-Red script, please be nice :)
