Any info? Also the aim would be to use as little battery as possible with the MPPT or RS Inverter and mainly use the surplus PV Energy for car charging. Is this doable?

Good question.
I have my EV Charger wired to the relay output of my Cerbo GX. I can now switch it on / off manually via the vrm portal but it would be great if there was an option to assign it to the SOC or other values such as Battery load and have it switch automatically.

Do you have a Victron EV Charger? Did you check if it supports Node Red?

You can also use the relay on a smart shunt or bmv to achieve the SOC switching.

Or have the charger on AC2 of an inverter that is also programmable on SOC

If you have a GX and the Victron charger this should be possible.

It also already has NodeRed integration so you can very easily setup your own rules to control it.

Also interested to know more about how the ev station can be switched off based on soc, both on and off grid systems. Doesn't seem to be possible now or am I missing something?

I use the relais output of one (I have 3 with 6,78kW total) of my SmartSolar to switch on a 3,6kW EV charger (I have only to switch on a Relays which switch a standard wall socket.


It switch on, if the SmartSolar goes into float.

Maybe it is even better to use Absobtion.
